It is amazing with all these dacs coming out today. For 399.00 bucks the D300 sure sounds like a great deal. The MA dacs are interesting for sure, the Aquarius sounds good from what I gleen on youtube from headphones (I know not really reliable) but not for that price tag. The one DAC that has really peaked my interest is the Ladder Shumann. Right now I am just streaming with Qobuz to my Denon AVR, so I will be upgrading soon.
