Tube amp for Sonus Faber Extrema?

I have a pair of guarneris and I would love to try the Extremas one day. My question is, since the Extremas require so much power to control the driver, do you lose the kind of subtle detail and beauty that the guarneris do so well?

I assume you pick up more dynamics and bass. thx, jeff

I move to my pair of Extrema with a Krell KSA-300s power, and really sounds great, great bass, the best midrange that you can hear and above all realism, incredible musicianship, I doubt any current Sonus, sound of this way.

I tell you my experience, require a power Extremely high power and excellent quality, and combine with a wire handle cran amount of current and of good quality, I to mine the probe 1 with a Krell KSA-50S and the sound was really unfortunate that gave, now when you buy the Krell KSA-300s is another world, I realized there that have absolutely crosover current applicant, in short all the electronics associated with these speakers should be of high quality, in order to maximize the enormous potential of a once achieved, is obtained to get the most complete musical nirvana!
