Modded

For sale iBasso DX90 portable audio player, very well taken care of (used only with case and screen protector), boxed and with original accessories, in excellent condition - almost as new. The amplifier stage has been modified in order to achieve superlative performance. Tested with a professional dScope audio analyzer, the modded player measures 0.00079% (-102dB) distortions under a 16ohm load and at a 500mV output! This is pretty much state of the art in professional audio territory, let alone for a portable device. For reference, under same conditions original schematic achieves 0.022% (-73dB), which is pretty good already but much below what the DAC chips can support and what can be squeezed out of this gem. Note that the power consumption increased by around 10-15% following the mod. Rockbox open-source alternative firmware has been installed (parametric EQ, dithering, gapless playback etc.). The player can be booted either with the original firmware or with Rockbox, should you prefer to use only the original firmware send me a note and will reset the player to factory defaults before shipping. Main Features: - Bit for bit playback, Support up to24Bit/192kHz - Dual ES9018K2M DAC - Built-in 10V Voltage Swing Headphone AMP - 2.4" IPS Screen (320*240) with Capacitive Touch Panel - Up to 24Bit/192kHz Mini Coaxial Output - 3.5mm Headphone Output, and Line Out - Three Physical Buttons (Previous,Play/pauses, Next) on The Top Panel - 256-Steps Digital Volume Control - 8GB Onboard Flash Memory - Support for SDXC and SDHC MicroSD Card,up to 2TB. (as They Become Available) - 3-Setting Gain Switch - Audio Formats Supported: APE, FLAC, WAV,WMA, AAC, ALAC, AIFF, OGG, MP3, DSD - Support for M3U Playlist - User Replaceable Battery (compatible with S3) The player comes with the following accessories: - USB cable - Jack to RCA SPDIF digital output cable - silicone case - velvet pouch - spare protective screen (NB: one already applied on the player) - original battery + spare Samsung battery; both in very good condition The item will be carefully packed and shipped with a tracking number.

For sale iBasso DX90J (Japan Edition) portable audio player, very well taken care of and in excellent condition. This is a great player that has developed quite a fan base given its quality, size, usability and versatility. In its Japanese incarnation (DX90J), it is supposed to have undergone additional tweaks and presumably it sounds a tad better than the international version (DX90). However, both DX90 and DX90J deliver rather modest performance with IEMs/low impedance headphones in their original form. Therefore in order to unlock the full potential and achieve superlative performance under any conditions, the player has been extensively modified. Tested with professional dScope audio analyzer, the modded player measures -101.3dB (0.0006%) total harmonic distortions under a 16ohm load at a 500mVrms/16mW output (compared to -58.5dB / 0.1189% before modding)! This is pretty much professional audio territory performance from a portable device, measured under real use conditions. Note that as a result of the modifications, power consumption increased by approximately 10-15%. Rockbox open-source alternative firmware has been installed (parametric EQ, dithering, gapless playback etc.). The player can be booted either with the original firmware or with Rockbox, should you prefer to use only the original firmware send me a note and I will reset the player to factory defaults before shipping. Main Features: Dual ESS Sabre ES9018K2M DAC Chips 2.4" IPS Screen (320*240) with Capacitive Touch Panel Up to 24Bit/192kHz Mini Coaxial Output 3.5mm Headphone Output, and Line Out Three Physical Buttons (Previous,Play/pauses, Next) on The Top Panel 256-Steps Digital Volume Control 8GB Onboard Flash Memory Support for SDXC and SDHC MicroSD Card,up to 2TB.

This is my own built Grado. This headphone are made from rose wood with leather headband with high end nhoord driver. It's cabled with high pure copper cable from France for a total of 8 core (0,35mm each) cable ended in 4 core for each channel. The built of the cable are made for provide the best conductivity and the best quality possible without sacrifice the flexibility of it. For finish the plug is a popular Viablue Jack. The headphone is entierly made with lot of care for the best durability and performance possible. Compared to an original grado PS500 the sound is lot of more fun, more warm and round with more bass/sub bass. For my self i will compare it between a PS1000 and a HD600 without lost the grado energetic feeling. It's your chance to get a really rare and unique headphone built to their highest spec ! I ship in France, europe and worldwide with insurance package. Take in mind that i'm not responsable for any custum fee tax for shipping. If you had any question i will reply it. Thanks !

For sale iBasso DX90 DAP, with original box and accessories, in excellent condition (has always been used with protective screen and case), working perfectly. While pretty good in its original form, iBasso engineers did cut some corners and the player does not reach its full potential. As such, the player has been extensively modified in order to improve performance:  - power supply and DAC stages have been redesigned in order to reduce the overall distortions and noise level, in particular at lower frequency where the original suffers the most (around 5dB THD+N improvement at 1KHz, 30dB (!) improvement at 20Hz)  - output buffering stage has been modified in order to improve performance with lower impedance earphones (with 16ohm load THD+N is improved by approx. 30dB) Measurements with a professional audio analyzer show that the modified player is reaching excellent performance under real life test conditions (line out: -105dB THD+N across pretty much most of the audible frequency spectrum, headphone out: -102dB THD+N while delivering 500mVrms under a 16ohm load). Included:  - DAP  - Original battery (in very good condition) + new spare battery  - USB cable  - Coax SPDIF out cable  - Burn-in cable  - Silicone case  - Spare screen protector (one already applied) The item will be carefully packed and tracking number will be provided. Shipping out of France, fast delivery and no taxes for destinations within EU.

ENGLISH VERSION AT THE BOTTOM Bonjour, je vends mon kit audiophile nomade: Ipod classic avec adaptateur interne pour accueillir 2 cartes sd. L'ipod est équipé de 2 cartes SD de marque PNY de 256go chacune, pour une taille de stockage nominale de 512go. (477 effectif, voir photo). Dans la vente il est inclus également l'amplificateur Toppping NX2 et l’adaptateur Fiio qui permet un branchement direct sans passer par la sortie jack de l'ipod qui est de moyenne qualité. Le Topping nx2 peut également faire office de audio DAC pour d'autres appareils (ordi, téléphone avec la fonction OTG, etc) Il tourne sous rockbox, mais il est possible de réinstaller Itunes en le branchant à l'ordi et en suivant la démarche de restauration. Conditions extérieures moyennes, mais en parfait état de marche. Envoi Colissimo avec assurance HI, I'm selling my modded Ipod Classic. It has an internal adapter with 2x256gb PNY SD cards, for a total of 512gb (477 real, see picture) I also sell my Topping NX2 amplifier which allows to bypass the output jack and have a clearer sound. The topping NX2 also works as audio DAC to use with a pc or an OTG smartphone. It comes with Rockbox installed, but you can revert to Itunes if you follow the restoration process from your pc. It has not very good cosmetic condition, but it works flawlessly Shipping all over Europe with insurance

I am selling my Creative ZEN X-tra (Nomad jukebox) audio player. It is the blue backlight version I am the original owner. It has some minor traces of use on the body, but it works like it was just bought (please see the pictures for more info). Over the years it had some modifications, which include: - Bought new original battery (three years ago - still holds charge pretty well) - Changed the HDD to a new one (two years ago). It can be modded to take Flash memory cards very cheap. - Bought an additional 3rd party battery (6 months ago) - Bought a USB charger for convenience and safety (6 months ago) All in all, the player is in very good working state, as it was taken care of. The player will be packaged alongside with original case (some scratches, but does the job), 2nd battery, USB powered charger and KZ ZST earbuds (used as spare - good condition). Please feel free to contact me if you have any questions!

Vintage 1981 Ibanez TS808 Tube Screamer Overdrive TrueBypass modded

Clone de la TB-303 modifié par Circuitbenders, en parfait état, hormis les stickers qui se décollent un peu. Fonctionne nickel. Moded by Circuitbenders clone of the famous TB-303. Fully working. Demo here: https://youtu.be/GSebDXf9rP4 Here are the specs: The MAM MB33 Retro is the latest version of the MB33 / FAT FREEBASS clone of the infamous Roland TB-303. As standard it features all of the original TB-303 controls, and also has an external audio input through the filter and VCA. Overlapping midi notes gives you that essential 303 note slide, and any midi note with a velocity of 120 or more will trigger the note accent. Realistically if this synth was programmed correctly, you would be VERY hard pressed to distinguish between this unit and a real 303 in a mix. In a side by side comparison i'd say it sounds a little meatier than the Behringer TD3, with a little more girth and analogue weight to the sound. We have modded this machine with our circuitbenders Acid FM mods to give a huge range of extra sounds, without diluting the essential TB-303 character. MODS INCLUDE: VCO On/Off Switch: Normally when you plug a jack into the external VCF input, the MB33's VCO is automatically removed from the mix. As there may be occasions where you don't want this to happen, or situations such as when you're using the filter lock mod (see below) when you want to be able to turn the VCO on and off yourself, we've added a switch to add manual control of this. VCO Drive: The MB33 retro seems to be designed to slightly distort the output stage at full volume, much like the TB303 did. The Drive mod boosts this distortion savagely for some grungy acid techno sounds. This mod increases the maximum amount of distortion at maximum volume. The intensity of the distortion can be set using the normal volume knob. Resonance Boost Switch: An annoying issue with these machines is that the resonance never reaches self oscillation (but then neither did the TB303) and also drops off considerably when the cutoff is over 3/4 of the way up. We've solved this problem by adding the resonance boost switch. With this switch activated the filter starts to squeal with the resonance about halfway up, and then just screams with self oscillation at any higher settings. The resonance boost is especially effective when used with the VCF FM mods. VCF FM: Essentially VCF FM (Frequency Modulation) allows you to modulate the filter cutoff at audio frequencies to create all kinds of clanging cross modulation and bizarre alien splatters & sweeps. This effect works best with the resonance cranked up into self oscillation which is where the resonance boost mod comes into play. The FM controls allow you to select one of four sources for the FM signal. The first is the normal filter input socket round the back. This means you can run a sound through the filter section, but also use that sound to modulate the filter cutoff at audio frequencies at the same time. The second source is a new FM input jack on the right hand side of the case. Using this source allows you to run a sound through the filter from the VCF input or just use the internal VCO, and at the same time modulate the filter cutoff with an entirely independent sound source at the FM in jack. The actual audio from the FM in jack is not heard. The remaining two sources are the sawtooth and square wave signal from the main oscillator. These can be selected as sources completely independently of the setting on the VCO waveform knob The FM source select knob also has an 'off' setting. The amount of FM applied to the VCF is controlled using the VCF FM knob. VCF CV input: This mods adds 3.5mm jack on the right side of the machine that will accept an external CV to control the filter cutoff. The CV input should range from 0-5v. Higher voltages, or negative voltages are NOT recommended. This mod also adds a switch on the front to toggle between internal and external cutoff cont

Le John Tucker (exemple audio) Modded Oppo UDP 205 est le meilleur lecteur numérique que j?ai jamais entendu parler. C'est la chose la plus proche que j'ai entendue d'une platine haut de gamme (15K et plus). Il a égalé ou surperformé les lecteurs numériques de la gamme 15K. La scène sonore vous enveloppe comme le ferait une plate-forme analogique. C'est tellement dommage qu'Oppo ait cessé de fabriquer ces unités. Voici votre chance d'en obtenir un avec très peu d'heures. L'unité a environ un an et est dans la boîte depuis près de six mois alors que ma salle d'écoute était reconstituée.
