I personally own a Chord QBD76 and have no urge to replace it with anything else since it sounds splendid in my system, for the money. I may be setting up another system and was wondering if there is a DAC in the lower price bracket that punches way above its price point, sounding close to if not better than the costlier designs @mryder
If you are enjoying the Chord ($5,000 give or take?), my personal opinion is that you may not be content with any $500 DAC.
I worked my way through all sorts of delta sigmas, and until I heard an R2R, I was not happy with my system. My first R2R was a Theta DS ProBasic III and I loved it. The sterile and analytical sound was mostly gone.Cost me like $500 a couple of years ago and retailed for about $2500 when new.
I decided to explore R2R a bit more and bought a Sorekris single ended just to try it. In my system, it is more detailed and analytical, while the Theta is more full and organic.
My most recent DAC purchase was a Mojo Audio EVO 3 ($3000 used) and it is a definite large step above both the Theta and Soekris. A general comment would be that it provides the detail of the Soekris and the body of the EVO. I can hear emotion in vocals better than before and no treble sterility.
I am waiting on a new Mojo Audio Mystique B4B and am counting on the higher quality parts and stronger power supply to get me closer to my version of nirvana.
While I am waiting on the new DAC, guess what I am listening to in the meantime? The Theta.
FWIW and YMMV
Thanks for listening,
