I have the StageDac and the Concerto. I could eventually upgrade to the Classic. Another option is the Violectric V200 as I don't need the crossfeed on the amp (given that I have it on the DAC).
Which one would you take, not considering money :
A - Nothing. The Concerto is as good as any of the other two.
B - The Classic. Why?
C - The Violectric V200. Why?
D - None of the above. What, then?
I use this combo with a range of headphones from Grado RS1i...
