@tomthiel A friend of mine who owns the DAC3B told me that it is thin on the bottom. He is a musician and knows more than me on how instruments and voices should sound. I also own the DAC3B and like the sound, it is clear, powerful, and fatigue free for me. I can see why people think it does not have a rich thick sound.
My Gustard X26 Pro was preferred by my friend over the DAC3B. He says it has the bottom that the DAC3B does not have. I like both DACs. I tend to listen to the DAC3B with my more warmer gear, such as KRELL which also has a lot of bass.
The Gustard is $1500 and a bit lower in cost to the DAC3B.
