Wyred4Sound µDAC

Mines #181, so I know it's rare and hardly been viewed. The software was simple and almost effortless to begin, with included CD. The box and unit was small, but heavier than it looks. The included USB cable is nice and long, looks like 5-6 foot and works perfect for my use. My set-up: From iTunes lossless files on laptop to USB on W4S Micro Dac to Monster interconnect cable to V-Can headphone amp to AKG K701, and also out of my V-Can to my receiver with Monster interconnects (which is a hella nice option on a headphone amp, and very useful in my current setup to let me run all my stuff through this dac.) So far I instantly noticed detail that I didn't notice from a CD player through the same amp/headphone combo, even though the CD player was claimed to have a good DAC. On the W4S DAC inputs I have my computer in the USB, my TV hooked through the Coax, and CD player hooked through TOS, and all input signals can be changed by a switch on the Dac. As far as DAC burn-in I think that just having the AC plugged in for 200 hours will complete it. Also, I think using the included AC adapter gives for the best sound quality, though there is a switch to use either USB or 9V AC power. I have not tested the difference and why wouldn't I just plug it in anyway? About 2 hours into listening and so far nothing but good. Even if you have a DAC 1 or 2, or other high-end DAC, this thing could go with you to the office or anywhere your laptop goes to get that sound you expect from home.
