It actually might not be the best quality source, but it certainly can sound extremely good and the convenience factor is off the charts.
Given that digital is my third string quarterback behind analog tape and vinyl I find myself feeling the same way about computer audio. Having just set up a wired Ethernet network for playback I can say that it bested my previous USB converter setup and comes pretty close to my former reference which was a CEC transport slaved to my Lessloss DAC. The convenience factor is definitely a plus.
I had a chance to meet the Lampizator folks at Newport and I have to,say their transport is enticing, but given how my digital setup,sounds now I may just leave well enough alone.
