" the best Tweak ever in the entire audio industry"

I put in the ss2590 and was very pleased with the results. I agree with Danny that this may have been the best tweak I've ever done.

@lanx0003   Head phones, over Youtube, doesn't do it justice IMO. Heard on a proper system it has deeper/wider soundstage and incredible seperation of instruments. It's somehting I'd never heard before. Bass was also better defined and had more texture. SS2590 is what I have. 

There are people who spend far more money on a DAC in an effort to achieve a tiny bit better. This is the LEAST amount of money I've spent with the greatest return by FAR!. I agree with Danny.
