I got rid of my CAL Alpha for an Audio Alchemy 3.0 and love it. It was less hassel, very clean and no tubes. The Alpha constantly searched for input if I was using a different source than digital. Also, getting up off my butt to chose toslink/coax or ? defeated the purpose of relaxing to music. All CAL d/a's are nice but usually come with garbage chinese or russian tubes. For around $250, you can't beat it.
CAL Sigma tube DAC question....
Contemplating adding a tube DAC to my existing player...are there any significant sonic benefits to this?...I am not made of money, so any honest feedback would be appreciated...also,if there is a better,cheaper option...by all means...let me know..thanks...
