The new Micromega MyDAC is the perfect link between your computer and your hi-fi system. It’s an asynchronous 24/192 DAC that delivers a world-class performance/price ratio. It delivers a wide soundstage, well-controlled bass, and accurate high-frequencies. Your desktop or nearly any other digital system will sound demonstrably better with the MyDAC. With both USB and TosLink inputs, virtually any digital source can be improved by the addition of the MyDAC. A 4- position horizontal rotary switch with anodized aluminum wheel allows easy selection between STBY – USB – COAX – OPTO.
The MyDAC's USB input works in asynchronous mode up to 24-bits/192kHz and accepts USB audio class 1.0 and USB audio class 2.0 modes without any driver implementation for Mac, and a with a custom Micromega driver for PC. USB asynchronous mode means practically no jitter thanks to two very low jitter master clocks (22.5792 MHz for multiple of 44.1kHz and 24.5760 MHz for multiple of 48kHz), with dedicated low noise power supplies, for the optimum performance from your digital files.
This is the only DAC at this price with a low-noise, designed-for-audio power supply.In fact, there are two dedicated power supplies -- one for the digital section, and one for the audio section -- which deliver customized currents tailored to each section's needs. And the MyDAC uses no capacitors in either the audio signal path or the power supply path, so there is minimal electrical interference.

iFi iDSD Nano
There's just something about the MyDAC that stands out from that crowd. If you're thinking about the Peachtree unit, be sure to give this one a listen first. While the iFi unit really shines with DSD streams, the MyDAC wins with PCM.
Oh, and none of the clicking or popping reported by others appeared on this unit. Hooked to Mac via USB, it's flawless.
Just for info, you have to provide the serial number on the back of the unit to download the drivers and a firmware upgrade. Their online directions want you to install a 1.2x driver, then firmware upgrade (always scary) then a 1.5x driver to take full advantage of the DAC's bitrate (USB 2). The 1.2x driver loaded fine, as did the firmware. I kept getting errors on the 1.5x driver, and finally went into the device manager of windows, and manually pointed to the downloaded 1.5x driver which then installed correctly. That's a lot of work if you aren't familiar with windows gobbledeegook. No driver downloads necessary if you are using a Mac.
Windows 8 is not 'unknown driver' friendly. Either is the Mydac. Hold the Shift key during restart to access ability to install unsigned drivers. I am dinging this dac another star because of usb drops at 24/192 settings (pops and static). This on multiple computers, 3 operating systems, and various cables. Troubleshooting this, I have learned a lot about digital audio and the myth and potential harm to sound at these settings. The static disappears at rational settings. The article on xiph '24/192 music downloads are very silly indeed' is quite enlightening.
I stand behind the sound of the Mydac (at rational rate levels) but it can't perform as advertised because of USB dropout. After reading this article and performing some of the tests there, however, I see no point in those settings anyway. Judge for yourself.
myDAC is very sensitive to the input. You have to use a very good interconnect for digital input if you want to play high sample rates audio. You will experience pops and clicks if any part of your audio transport/interconnect introduces jitter. This includes your audio player. If you are connecting the DAC with your computer and your software or drivers upsample the sound in real time with mediocre quality, you will hear pops. Make sure you use a player that can get exclusive access to audio out and switch the physical sample rate to match the file specification. If you want to use myDAC with iTunes on OSX, you have to go in Audio MIDI Setup and manually switch the physical sample rate of your audio device to one matching your input file.
Also if you turn the DAC on and then turn it immediately off, it will make a noticeable, although not very loud, pop noise. This won't happen if you turn the DAC on, use it, and then turn it off. I must concede this is an engineering error, but given the sound quality I am getting out of 250$ of material, I couldn't be any happier with it.
