Jtnn, might I suggest you contact Sonus Faber directly and ask them about this particular combination in regards to the Amati Homage, they know this amp well. I have heard many amps and speakers, which amplifers were you wondering about specifically?
My recommendation is not based upon pure assumption but rather upon personal opinion and experience. Does this mean only those who actually own the Amati and experimented with nearly every tube and SS amp in their own home may provide opinions here? Well, I think thats fine if that was the intent but this was not expressed by the person who began this thread.
The one thing a 70W tube amp lacks is the power to drive every large full range speaker on the market(room size is also a big factor), the reason I suggested the Berning is because this individual is looking into other tube amps like the BAT and Nagra (yes, I have heard both).
