Cary 805 questions; with Sonus Faber Amati Homage speakers


I just bought a pair of Sonus Faber Amati Homage speakers (92 dB efficient but some impedance dips in bass and treble). Looking for a good tube amplifier. I use a Thor TA-1000 preamp and listen to mostly vinyl (Sota Star Sapphire, Koetsu Rosewood Signature. Half jazz, the rest split between blues, classical and rock. I am quite allergic to any treble brightness but appreciate treble extension if it doesn't create fatigue. That said, I prioritize a rich, real midrange, and like a somewhat laid back stage perspective.

Stereophile described the Amati load as "The speaker is a moderately demanding load, however, as can be seen from its plots of impedance magnitude and electrical phase angle against frequency (figs.1 and 2). With a maximum of 7.8 ohms, but a value below 6 ohms in the midrange and below 4 ohms in the bass and high treble, a good 4 ohm-rated amplifier will be called for."

I appreciate any thoughts about other tube amps that might be good with the Amati's. Also I have questions about Cary 805 monos in particular because I have a chance to buy a pair locally:

1. Do the 805s have a forward presentation?
2. Do the 805 create "larger than life" images? I owned them for a short time quite a while ago and recollect that images were very big.
3. Does anyone know if they would work well with the Amatis?

thanks for any thoughts!

 The Sonus Faber Amati Homage speakers are very nice speakers. You really want around 100 wpc in a tube amp. I know they are 92db. I have Sonus Faber Elipsa SE and use a Ref 110. If you don't have enough power the bass and sound stage can suffer. With less power, the bass of my Elipsa SE sounds less defined and not as crisp.

 You really need to just borrow a few different amps from a dealer and spend a few weekends comparing. The usual paring with Sonus Faber are Audio Research or McIntosh. But I am sure there are others brands that will work just as well. 


Thanks lostbears. I am okay with the bass being a tad flabby so I don't mind using less power. My priority is avoiding any etch/brightness, and having a relatively rich balance with a weighty midrange. 

George's point about impedance mismatch was certainly true of my current amp, a VAC Renaissance 30/30 Signature. I love this amp and think it is one of the best anywhere, but with this particular speaker the treble just did not work... beaming/shouty treble in the 2500-4000 hz range. But the bass is fine for me. So I am hunting for a new amp.
Mac 275? Is that the likely suspect? If so I've heard mixed things about certain versions... any special version you would recommend?
Depending on budget, perhaps consider the Jadis line...the JA80mk2 or the JA200mk2. I utilize the smaller JA30mk2 with my SFGH’s and I think it is a superb match.
