After 2 years owning the Dave I finally tried to go singleended (rca) from Dave to Diablo. Quite a step up. Then I changed Dave to preamp mode and set input 3 in Diablo to AV - connection, thus skipping the Diablo preamplifier. This also a step up and now I really understand how good the Dave is. Should have done it long ago.
The conversion in Dave from unbalanced to balanced is not good enough. Better to use singleended.
I moved the xlr-cables from Dave to the Scorpio cd-player, so going directly to Diablo. But it doesn’t provide the rhythm, attack, speed and 3-d like the Dave does.
