I had the DAC 7 and I thought it was very musical and super smooth with a nice analog-ish tonality across the spectrum. If you don’t give a crap about having all the latest features, the DAC7 is a home run. It took me awhile to find another Dac that impressed me enough to let it go. In comparison, I found the majority of newer Dacs either too detailed/fatiguing or at a price vs performance that I couldn’t justify. Ultimately I chose the Denafrips Terminator I and I’m quite pleased with it although I’d love to get my hands on the tubed Dac9!
