Yep, after nearly a year with the Dac-19 10th anniversary/Amanero Combo I'm still enjoying it. That said, I have two nagging issues left to conquer specifically with respect to the DAC (since external factors such as amp, headphones/speaker, and RCA interconnects are not directly related):
A) I'm still curious what it would be like with a really high end transport as source into the coax, versus the USB... But I may never know, unless I fork out some dough for such a transport.
B) Still trying to figure out how to get really amazing streaming quality, since I find that supposedly lossless sites like Tidal and Classics Online HD*LL both sound slightly less good than regular bit accurate methods of listening to flac or wav files on my computer (i.e. by bypassing any kind of OS filter with ASIO or KS).
