Sonus Faber Venere 2.5 amplifier Recommendation


Using a Conrad Johnson MV55 at 45wpc. Feel like I need a little more control of the bottom end. Does anyone have a recommendation for an amp or integrated that is synergistic with these speakers.

Thank you for your responses. I borrowed a friend's roguee audio at 100 wpc tonight. It did tighten the bottom end up but sounded less transparent than the cj and it's el34. Would prefer tubes but is this a speaker that needs solid state for best performance.?
I would say solid state power and a tube pre, would be the magic combo.

Unfortunately I can't pull them into the room as there is no space it is a very tight fit. But this might very well solve the problem.

A wide variety. In heavy rotation now is classic jazz.  But listen to rock as well that is where things get more confused. Vocals on the other hand sound great.
