My Raven Silhouette is a tube amp and drove my difficult Raidho C3.0 with ease.
I listen to a lot of large scale symphonies. I have tried 6 different amps and the Ravens won out. I also had ARC VT80SE and they were great with easier speakers like the Focals Electra 1038BEs, Tyler linbrook, usher mini dancer, but struggled with sopra 2 and Raidho
NAD C298 was laughably bad. Tried it due to accolades everywhere. Can’t believe magazine reviews.
I might be selling the Ravens to go with SET due to a high sensitivity speaker change.
They never come up for sale because the actual owners hold on to them.
