    iFi Audio Micro iDSD DAC and Headphone Amp - with Pre amp Variable out. There is nothing like the micro iDSD. It is literally, out of this world. It is the only DAC in the world (at any price) to play True Native Octa-DSD512/PCM768/Double DXD. Its Perfect-Match means it can be fine-tuned to any headgear from IEMs all the way through to large headphones. Its 8v/4000mW output makes it one of the most powerful headamps to drive even the most hungry of headphones with ease. iFi has forged an enviable reputation for being at the forefront of computer audio technology. The micro iDSD has just made another leap, an Octa-Leap to be precise. With its special Dual-Core Burr-Brown native DSD/PCM chipset at the heart, the micro iDSD is capable of True Native PCM768, Octa-Speed DSD512 and 2x DXD; it is simply out of this world. The micro iDSD has 3 different power modes Eco, Normal and Turbo. Capable of 4000mW, 1000mW or 250mW, the micro iDSD is able to drive the full gamut of headphone and amplifiers alike. With iEMatch there to dial to suit any IEM, the micro iDSD has redefined the headphone amplifier class. Used along with the analogue volume control, the diminutive size of the micro iDSD belies its uncanny ability to drive virtually anything and everything! SmartPower® is the micro iDSD’s onboard recharging feature for Smartdevices. Its 4800mAH battery is able to fully recharge an iPhone two-times. Compatible with Apple and Android, phones and tablets, it is another example of iFi’s commitment to customer needs – enjoy high-end audio on the go without worrying about the phone going flat. iFi’s iCAN and iTube have already achieved widespread acclaim, so much so that their core features including 3D Holographic and XBass have become renowned in their own right and imitated by others. In the micro iDSD, for the first time in an iFi product, it features XBass and 3D Holographic for Headphones and Speakers. All these features are still executed in the analogue, not digital domain to preserve the original music format. And so much more….with the amazing Crowd-Design program, we are over the moon that you, the customer was central to the development of the micro iDSD. The micro iDSD is literally bursting with features – such as Direct/Pre-Amp, 3.5mm input, SPDIF Input/Output and much, much more. You will have to see it to believe it.   Specifications:     Item Description Remarks Inputs/Outputs     Inputs (rear) USB 2.0 type A “OTG” Socket (with iPurifier® technology built-in) Compatible with computers (Apple/Win/Linux), iPhone, iPod Touch, iPad and Android Devices, camera kit or USB-OTG cable required.

"The A-3s are the most perfect embodiment to date of my ideal loudspeaker system. Never in my life have I lived with a speaker that has brought, and continues to bring, as much pleasure, excitement, and satisfaction. In short, I am madly, passionately in love with their sound, and I hereby give notice to Roger West that he is going to have a hell of a hard time prying them loose from me." J. Gordon Holt - The founder of Stereophile I'm selling a beautiful pair of Sound Lab A-3 electrostatic speakers in better-than-new condition. New mylar membranes have been installed the last year. Electronic parts have been upgraded by Roger West himself to Toroid 2 level one month ago. I've made a custom wood frame to accomodate new transformers (which are too big to get inside the original frame). Speaker's impendance has been raised as well.   This is the only pair of A3 upgraded to Toroid 2 level worldwide (as Toroid 2 upgrade has never been made before for A3 speakers). New toroidal transformers and higher sensibility make them easy to drive with any decent amplifier. So, this particular pair of A3 is not only in a virtualy new condition, they also sound better than new. The sound can be described by one word only: glorious !  I have compared Soundlab A3 to Quad ESL 2912 and Stax ELS 8X in my room. Soundlab are MUCH better in every possible way. They have completely different sound dispersion pattern, which makes them sound more lively, more organic, more life-like, and more dynamic. They will create in your room a spectacular gigantic immersion-space, much bigger and more lively than any other speaker regardless of the price. I have original crates so I can ship anywhere (on two pallets). Please contact me to discuss about shipping options and costs. If you live in Paris, you are welcome to test them in my home. After hearing them you will immediately sell your Quad, Martin Logan, Apogee, Magnepan... or any other speakers you currently have. Keep in mind that the current line of Soundlab speakers starts at 22.000 $ price tag.
