Le lecteur SACD multi-sources English description at the end Le MP 2500 R est le plus récent et le plus sophistiqué des lecteurs multi-sources et PCM / DSD DAC série R.  Le MP 2500 R est construit conceptuellement et technologiquement comme le MP 2000 R MKII. Les deux appareils sont spécialement conçus pour la lecture sans compromis de données audio haute résolution. Au lieu d'un lecteur de CD, nous avons équipé le MP 2500 R de notre tout nouveau lecteur SACD du SACD MP 3100 HV haut de gamme. Comme dans le MP 2000 R, nous utilisons notre convertisseur quadruple différentiel double supérieur avec traitement de tous les signaux numériques pour convertir les données PCM. Pour les données DSD, le convertisseur DSD analogique 1 bit T + A True unique est utilisé, qui ne convertit pas les données DSD mais les traite nativement en flux binaire. Cela signifie que même les données DSD jusqu'au DSD 512 provenant de l'entrée USB du tableau de connexion numérique peuvent être reproduites avec la meilleure qualité. En tant que client de streaming, le député a 2 500 R obtenir le T + un conseil en continu de haute résolution, qui permet non seulement la plus haute résolution, mais aussi l'utilisation de différents services de musique, radio Internet et la connexion au réseau domestique via LAN et WLAN, le mode maître USB et streaming HD à partir de serveurs de réseau.L'excellent accordeur sonore est compatible FM, FM-HD et DAB +. Un module de diffusion Bluetooth de haute qualité pour la transmission de musique depuis des appareils mobiles est également installé. Le fonctionnement du PM 2500 R, ou même un système R ensemble, via le FM1000 de commande à distance infrarouge ou au mieux sur l'application de contrôle T + A. Cela a servi, par opposition aux applications de nombreux autres fabricants, notre équipement est complet dans toutes les fonctions et montre non seulement les informations du client de streaming, mais aussi le contenu d'affichage de toutes les sources, telles que le nom de la station et le texte de la radio lors de l'opération FM. En option, la télécommande bidirectionnelle FD 100 peut être utilisée. Il ne représente pas seulement l'affichage de l'appareil, mais couvre également l'art. lecteur SACD drive Précision entraînement linéaire. Système laser double: SACD: 650 nm, CD: 785 nm formats SACD Stéréo, CD / DA, CD-R, CD-RW, SACD / CD Text Réponse en fréquence et dynamique SACD: 2 Hz - 44 kHz / 110 dB, CD: 2 Hz - 20 kHz / 100 dB Streaming client formats MP3, WMA, AAC, OGG Vorbis, FLAC, WAV, AIFF, ALAC débits de données PCM 32... 192 kHz, 16/24 bit; MP3 jusqu'à 320 kbits, débit constant et variable traits Lecture Gapless pour MP3 (Lame), WAV, FLAC T + Une application de contrôle pour iOS et Android normes Contrôle UPnP AV, T + A services: Tidal, Deezer, qobuz (abonnement requis) interfaces LAN: Fast Ethernet 10/100 Base-T, WLAN: 802.11 b / g / n Tableau de connexion numérique Entrées numériques S / P-DIF 1x AES-EBU, 1x coaxial, 2x BNC, 2x TOS-Link USB (mode périphérique) 1x mode périphérique USB asynchrone USB (mode maître) 2 x mode maître USB pour le stockage de masse USB Tuner FM norme de réception: FM, FM-HD gamme de fréquences: 87,5-108 MHz; sensibilité (> 65 dBA S / N) 1 μV Headroom: 103 dB uV THD: 0,1% Signal / bruit distance mono / stéréo 72/62 dB séparation stéréo 50 dB Deemphasis (version Europe / États-Unis) 50/75 nous services de données:RDS / RDBS, nom de la station (PS), type de programme (PTY), texte radio (RT) Tuner DAB norme de réception DAB, DAB + gamme de fréquences 168-240 MHz (Volume III) Sensibilité (BER = 10 - 4) 2,0 μV Headroom 103 dB uV Bluetooth A2DP (audio), AVRCP 1.4 (contrôle) / aptX®, MP3, SBC liens Sorties analogiques haut niveau (RCA):2,5 Vrms / 50 ohms Sortie analogique symétrique (XLR):5.0 Vrms / 50 ohms Sorties numériques:1 x coaxial, IEC 60958 S / P-DIF (LPCM) Convertisseur N / A PCM quad différentiel double convertisseur avec 4 convertisseurs N / A par canal, 32 bits Delta Sigma, 352,8 KSPS / 384 KSPS DSD Convertisseur N / A DSD T + A-True-1Bit jusqu'à DSD 512 (22 MHz) Réponse en fréquence PCM 44,1 kSps 2 Hz - 20 kHz Réponse en fréquence PCM 48 ksps / dsd 64 2 Hz - 22 kHz / 2 Hz - 44 kHz Réponse en fréquence PCM 96 kSps / DSD 128 2 Hz - 40 kHz / 2 Hz - 60 kHz Réponse en fréquence PCM 192 kSps / DSD 256 2 Hz - 80 kHz / 2 Hz - 80 kHz Réponse en fréquence PCM 384 kSps / DSD 512 2 Hz - 100 kHz / 2 Hz - 100 kHz filtre analogique Filtre Bessel linéaire symétrique, phase 3, 100 kHz THD Signal to Noise Ratio 116 dB la séparation des canaux 110 dB Connexion / Accessoires / Dimensions Interface de contrôle R2-Link contrôle à distance FM 1000, T + A Control APP, télécommande d'affichage optionnelle FD 100 raccordement au secteur:100-240 V, 50-60 Hz Consommation électrique max.:40 watts Eco veille:0,3 watts fonction de mise hors tension automatiqueoui (après 90 minutes sans signal audio) Dimensions (H × W × D):16,5 × 46 × 40 cm poids: 11,3 kg T+A MP-2500R Media Player SACD/CD/DAC/Streamer/Radio The Multi Source SACD Player The MP 2500 R is T+A's newest and most sophisticated Multi Source Player and PCM / DSD DAC in the R-Series. The MP 2500 R has the same overall design philosophy and technical facilities like the smaller MP 2000 R MK II player. Both have been developed to reproduce high-res audio files without any trace of compromise. Instead of a CD mechanism T+A have equipped the MP 2500 R with the SACD drive from T+A's High-End SACD player MP 3100 HV which is a completely new development.  As in the MP 2000 R MK II, PCM data is converted using T+A's outstanding double differential quadruple converter with all it‘s sophisticated digital signal processing. DSD data are handled by the unique analogue T+A true 1-bit DSD converter from the PDP 3000 HV, which processes the DSD data in native form as a bitstream rather than converting them. This makes it possible to reproduce DSD data up to DSD 512, as delivered by the USB input of the digital connecting board, to the highest level of quality.  The machine’s streaming client takes the form of the new T+A high-res streaming board, which provides maximum resolution as well as the facility to access various music services, Internet radio, inclusion in the home network via LAN and WLAN, USB Master Mode and HD streaming from network servers. The digital tuner offers FM, FM-HD and DAB+ capability, and delivers excellent sound. The T+A MP 2500 R also includes a high-quality Bluetooth streaming module for transferring music from mobile devices.  The machine is controlled using the FM1000 infra-red remote control handset, or – ideally – the T+A Music Navigator App. In contrast to many manufacturers’ Apps, this is capable of controlling every element of every function of T+A's machines. Not only does it display the information pertaining to the streaming client, but also the screen content of all sources, such as the station name and radio text when used in FM radio mode. As an option the FD 100 bi-directional RF remote control system can be used as well. It displays the full content of the device screen and coverart as well. Technology It is only natural that the SACD and CD continue to lose significance, as they are increasingly superseded by streamed content; a trend reflected very clearly in the huge success of T+A's multi-source players with their extensive streaming facilities. However, it is clear that T+A audiophile customers still wish to be able to play music from CD and SACD, because none of us wants to throw away our old collection, and in any case there is an undeniable charm in owning a tangible data medium. Infact the SACD is currently experiencing what we can only term a renaissance all over the world. Therefore T+A decided to develop a completely new, modern SACD mechanism incorporating the latest decoder technology, offering very short access times and outstanding error correction. It is capable of reading CD (PCM 44.1 kSps) and SACD (DSD 64 2.8 MHz) discs at the highest possible quality. T+A have invested a huge amount of effort in the mechanical design of the drive unit, incorporating a high-quality drive, double laser optics and heavy-duty motors. With the aim of eliminating all traces of interaction between the moving parts of the disc drive and the remainder of the player T+A's disc mechanism features a mechanical isolation. A heavy aluminium plate and a solid case, which act as a mass damping devices, thereby preventing any structural sound from the mounting surface finding its way to the electronics and the disc mechanism. The disc drawer runs on two accurately machined stainless steel pushrods, while the disc rests in a specially coated, high-quality ABS cradle.

Rare paire Luxman C300 et M300:Amplificateur et préamplificateur (avec phono). État : "Occasion" En excellent état de fonctionnement, notez qu' il faudra remplacer une ampoule du voyant Led  "classe A". Voltage 220V. Les deux appareils sont visibles chez Jefferson Hifi à Pérouse où je les ai déposés. Livraison possible en France, en Europe,etc nous consulter pour les frais d'envoi internationaux. Le M300 a été produit en même temps que la série C300. Je crois qu’il n’en a été produit que 2000 dans le monde. C’est non seulement une paire de collection, mais le haut de gamme des luxman des années 1980. Ils sont les dernières combinaisons pré/ampli, à avoir été fabriquées sans implication de Alpine(qui a ensuite  modifié sérieusement la qualité Luxman  hélas.). ils ont été primés "produit de l'année" au début des années 80.  Le M300 se laisse utiliser soit en classe A, où il développe 2x42 w sous 8 ohms en classe A, ou alors 172w en classe AB sous 8 ohms. Comme toujours chez Luxman, on peut espérer une dizainede watts supplémentaires dans chaque modes, vu qu'ils utilisent unsystème de mesure très strict sur leurs fiches techniques. Il faut surtout savoir qu’il ne faut basculer de classe AB en classe A que à l’arrêt, en redémarrage à froid.  Voici  les caractéristiques techniques (https://audio-database.com/LUXMANALPINE-LUXMAN/amp/m-300-e.html) et https://audio-database.com/LUXMANALPINE-LUXMAN/amp/c-300-e.html 1)Préampli C300: Frequency response: 0.5Hz to 140kHz   Total harmonic distortion: 0.005% Input sensitivity: 0.09mV (MC), 2mV (MM), 140mV (line)      Signal to noise ratio: 80dB (MM), 100dB (line) Output: 140mV (line), 1V (Pre out), 20V (Pre out Max)  Dimensions: 478 x 163 x 384mm     Weight: 9kg 2)amplificateur M300 Form Duo beta plusX poweramplifier Succession effectiveoutput (20Hz - 20kHz, both channel simultaneous operation) Class-A: 40W+40W (8ohms) AB class: 270W+270W (4ohms) 170W+170W (8ohms) THD (8 ohms) 20Hz- 20kHz-3dB Class-A: 0.005% or less AB class: 0.005% or less Cross modulationdistortion (8 ohms) 60Hz: 7kHz=4:1, -3dB Class-A: 0.005% or less AB class: 0.005% or less Output bandwidth Class-A: 10Hz-100kH-3dB(0.015% of distortion) AB class: 10Hz - -100kHz three dB(0.04% of distortion) Frequency characteristic 10hz-100kHz-1dB (aClass-A and AB class) Input sensitivity Class-A: 0.45V ABclass: 1V Input impedance 50kohm (a Class-A and ABclass) SN ratio (IHF-Acorrection) Class-A: 115dB ABclass: 120dB Remains noise (IHF-Acorrection) 30 microvolts (a Class-Aand AB class) Dumping factor 120 (1kHz, 8 ohms, aClass-A, and AB class) Protection network DC drift detectionspeaker protection network Overcurrent detection amplifierprotection network Attachment Circuit operationswitchpoint (indicator) Peek indicator Inputattenuator Headset jack Speaker-off switchpoint(indicator) Line phase sensor Supply voltage AC100V, 50Hz/60Hz Power consumption (Electrical Appliance and Material Control Law) Class-A: 420W ABclass: 430W Dimensions Width 478x height 214xdepth of 484mm Weight 30kg Stereo power amplifier which adopted the Duo beta plusX circuitry. In order to control NFB of an amplifier circuitry appropriately, the Duo beta circuitry was developed and it is adopted as M-300. After this makes amplifier to the extent that it is used also from a nakedness property as it was, it adds proper-quantity NFB and DC servo as finish of a tone quality, and is suppressing the transitional distortion of a supression of play sound, TIM, etc. by superfluous NFB etc. Furthermore, in M-300, the thought of a suitable control is introduced also into a power circuit, and it is considered as the power-source Duo beta plusX. At plusX, the stability of a comfortable tone quality and an operation is reconciled because the bottom gives controlling force calmly on the assumption that a generous power-source part. M-300 can change and use a Class-A and AB class. The Class-A operation has a structure which amplifies a signal wave form as it is. Therefore, it becomes unrelated to switching distortion or crossover distortion, and does not have the cause that it is distorted in addition to an element's own linearity. In M-300, the Class-A operation excellent in adopting a Duo beta as LAPT which excelled [element] in the high region property, and an amplifier circuitry, and adopting plusX as a power circuit is realized. In AB class, Oide power which drives transitional distortion below into a limit of measurement in pursuit of a nakedness property also in an operation, and is not made in a Class-A operation on it is realized. At the time of a switching of a Class-A / AB class, in a performance, sound does not break off and a noise is not generated, either. Circuitry constituted all the amplification stages from a push-pull circuit from the input stage to the output stage, and the amplifier which was excellent in the nakedness property which will be the requisite for a Duo beta circuitry is realized. The pre-driver stage is making the input stage the transistor which was excellent in the high region property with the cascode interconnection with the stream composition of the cascode bootstrap and the differential push pull by complimentary FET of a Pch type and a Nch type. And the driver stage and the power stage are considered as the push pull stream composition by a three-step Darlington connection. A linearity makes an output element high speed power transistor linear arithmetic processor-T which was well excellent in the high region property with a triple push pull stream composition, and the electric current is sent. In this way, the static characteristics and the dynamic behavior improved. And proper-quantity NFB and DC servo are added. The power-source part had the twin monophonic stream composition of right-and-left full independence, and has acquired the merit of a linearity covering all the bands, and the outstanding crosstalk property. The power transformer is performing and using the coil mandatory adopted and put into practice among the object for Rch, and two Lch. First, the power stage and the drive stage were made into another coil, and also the primary side and secondary side has unified the orientation of a coil. This is because it is checking having influence on play sound with the potential (polarity) which a transformer begins to roll, rolls and the last each has between opposite groundings. Moreover, four right and left adopt the type only with a capacity of 12,000 micro F for an audio as a filter capacitor, and low-impedance-ization of the power-source part is attained to it. In order to cope with the rush current which becomes large as the capacity of a power-source part becomes large, the rushes current preventing circuitry is adopted. The speaker protection network and the amplifier protection network are carried. The internal organs of the speaker protection network which detects DC output in an output-terminal and separates an output are carried out. Furthermore, when the speaker code etc. short-circuits, even if there is a big input, an amplifier circuitry is protected or the electric-current preventing circuitry is carried. After the elements currently used examine, it is using it, carrying out a tone-quality mandatory strictly uniquely. The film capacitor generally called non-polar is also arranging a polarity etc., and the capacitor is carrying out the tone-quality mandatory strictly. Moreover, the precision succession good transformation Detent volume excellent in the tone quality and a feeling of an operation is adopted as input attenuator. Furthermore, in terminals, the small gilding pin jack of contact resistance was adopted as the input terminal, and the large-sized screw type is adopted as a speaker termination. The product line was packed into the shortest distance, and also it has chosen high materials of the tone-quality effect, such as a shielded cable of oxygen free high conductivity copper and 500 core. Moreover, in order to suppress an elevation of the source impedance of the pattern side of a substrate, the power bus by a copper plate was adopted and the performance of a power source is employed efficiently. The line phase sensor is carried, by the functionality which detects this polarity, the polarity of the equipment was unified and the tone quality is improved. The indicator turned on at the clipping point of an output is carried, and a peek can be supervised.

I'm selling this MATRIX X-SABRE PRO MQA DAC, one of the best sounding dacs I have ever owned, and i have owned quite a few in my lifetime !  It is in perfect condition, just as new (i take very good care of my audio gear), and comes with a usb cable and a power cord. It also comes with a remote control. I'm selling it with regret, but i am going to upgrade for a much more expensive dac/streamer. I hope the one i get will sound as good as the Matrix !  It is one of the best rated dacs by the audio science review ! (See article below) It can read any audio files, including mqa from a lot of sources (streamers) with a musicality that will put chivers to your spine ! You can ear each instrument very clearly and with a lot of detail but no harshness. It retails at 2200 euros, i'm selling it at 1400. It's a bargain for music lovers ! Cheers ! Service de livraison : Colissimo The Matrix gets a lot of positive reviews in the audiophile community. Just check it out: https://www.audiosciencereview.com/forum/index.php?threads/matrix-audio-x-sabre-pro-mqa-best-audio-dac-in-the-world.8729/ Steve Guttenberg's video review: https://www.youtube.com/watch?v=IUZCGOoxLSU Unboxing video: https://www.youtube.com/watch?v=4qIvDWqPN9o The Matrix Audio X-Sabre Pro MQA is beautifully made, putting to shame many products in its price range. It oozes class and quality. That beauty runs deep when it comes to performance as Matrix Audio X-Sabre Pro MQA unseats its own brother to take the crown of the best DAC I have ever measured. Considering that the list now includes nearly 160 DACs, this is an incredible achievement. I met the team behind Matrix Audio at the last audio show and you have not seen a more soft-spoken, unassuming team of engineers than them. None of the ego that is so prevalent in high-end audio. The company is active here and on some other forums. And of course volunteers to have its products tested by us, rather than hiding in the bushes. So they score high on both product and customer service. Needless to say, it is my absolute pleasure to recommend the Matrix Audio X-Sabre Pro MQA. We are here to find the best engineered audio products and the Matrix Audio Proves that it is among a handful of companies to produce such trophy class products one after the other. It put a huge smile on my face after testing it, one that will be hard to erase! Description Matrix Audio, in partnership with MQA Ltd., has created the MQA-supported X-SABRE Pro audio DAC to let you experience the abundant music details in the artists' recording room. X-SABRE Pro is an MQA-enabled DAC which can fully decode the original MQA files without any assistance from third party software (MQA Core Decode). Powerful Hardware Platform X-SABRE PRO (MQA) used the ES9038PRO advanced 8-channel D/A chip, and its inner DSP unit and analog circuit have the high performance and better user experience. The new generation XMOS XU216 USB asynchronous transfer interface and new AK4118 S/PDIF receiver chip, with powerful computing performance and multi-channel processing performance, make X-SABRE Pro (MQA) has excellent digital audio conversion capability. IIS Port X-SABRE Pro (MQA) is equipped with the most complete input ports of this series, in addition to optical, coaxial, AES/EBU, USB ports, we even added a IIS·LVDS input via a HDMI connector to differential transmit IIS signal, maximize the transmission performance of the IIS port, to make the data from the short-distance transmission between the chips into high-speed interconnection between the devices, get rid of the USB transmission or S/PDIF transmission re-encoding, and let the original digital audio stream directly into the D/A chip. More Sampling Rate Supported X-SABRE PRO(MQA) can support the Master Quality Authenticated coding technology developed by UK MQA Limited which can decode the MQA audio s

Les nappes et câbles LVDS (Low Voltage Differential Signaling) d'une TV LG, comme le modèle LG 43UH603V, peuvent parfois être compatibles avec d'autres modèles de téléviseurs, mais cela dépend de plusieurs facteurs: 1. Modèle de la carte mère et de la carte T-Con: Si les cartes électroniques (carte mère et carte T-Con) de deux modèles de TV sont identiques ou très similaires, il est probable que les nappes et les câbles LVDS soient compatibles. 2. Résolution de l'écran et technologie d'affichage: Les nappes LVDS peuvent varier selon la résolution de l'écran (Full HD, 4K) ou la technologie (LED, OLED). Il est essentiel de vérifier si les caractéristiques d'affichage sont les mêmes entre les modèles. Article Garanti En savoir plus Collaboration commerciale.
