Since nobody mentioned it, RWA Isabellina NOS non-upsampling, non-oversampling DAC for $2500 or $1500 option for Isabella preamp.
I am not what you might call "DAC expert" but after hearing quite a few fine DACs lately, I believe that Isabella is on par or above competition......at least in its asking price range.
I can not recommend it or guaranty that it will be to your taste ....but if digital reproduction shortcomings like edginess and lock of body/emotions are what stopped you from enjoying your favorite music, I would at least give it a shot with 30 days money back warranty.
There are probably better choices out there but I would seriously doubt if I could afford it.
After a long while, I am starting to enjoy my digital ones again.
If that isn't the the sign of a really great product, I do not know what is.
