Sonus Faber Cremona Auditor - 50 watt tube amp ok?

My local Sonus dealer was recently running Cremona's using a 50w Nagra amp with excellent results. They also heard from Sonus that they use a 50w tube amp when developing and testing their speakers so you should be fine with 50W as well.

great info.thanks!

ive auditioned these speakers in three stores..they need LOTS of power...which is why i am hesitating about whether to buy them...the problem emerges at low volume -- they just don't sound very full, so you feel like you need to keep turning up the volume
