Integrated amplifier below 1.5K for Sonus Faber?

@Vangoughear: I would make some study on MF A3.2 then, thanks.

@Groovybassist: Nait5i is very analytical but not musical, it works best for fast rhythm music, my music taste more towards classical, jazz, new age music. Appreciate your recommendation though. I am looking for int. amp which is tube-like solid state giving warm, neutral, clear soundstage.

Auronthas: I don't consider the Nait analytical at all. Typically analytical gear spotlights detail and bleaches tonal colors. While the Nait isn't tube-like, it isn't bleached either and is surprisingly warm in terms of tone. In terms of detail, Naim gear (including the Nait5i) isn't known for retrieving the last layer of detail on a recording. Timing is important to all types of music and you might find the Nait is a perfect foil to the slower, more relaxed presentation of the Sonus Faber's. I only commented as you listed it under options you're considering and I have experience with it. Good luck finding what you're searching for. I'll continue to enjoy my Nait5i for all genres of music.

You might want to add a used Arcam fmj A32 to the list. I find it an amazing value for the money. Plus you get so much more than most standard integrateds.

Groovybassist: Thank you for sharing experience. I will make some audition on Nait, Cambridge Audio 540C and Sonus Faber. I see your CD player is also Naim as well as interconnect, probably its make your system sound great.

I have the AA Primo Settanta integrated amp and in many ways it is the best amp I ever had. It is not quite as refined as my YBA Design integrated or as powerful as my Classe CA100, but it is more engaging. It is extremely tubelike yet clear sounding, yet it is more engaging than my Pass Labs Aleph 30. That is its strength...engaging...it draws you in to the music like a good tube amp.

You can look up my system to see it. If I ever upgrade I can say this amp will be used in a bedroom system, as I'm not parting with it.

The key to its beautiful analogue sound is the use of power packs - the same ones Jeff Rowland and 47 Labs use, but at a budget price. AA doesn't advertise these facts as the other manufactures do, but they are there. Here are some brief thoughts on this amp that I posted: forum.audiogon.com/cgi-bin/fr....

As far as the other AA amps, here is the basic facts:
The Cento VT is the same Primo Settanta integrated w/ a tube preamp. It is a smoother and not as dynamic.
The Verdi Settanta has the same powerpack amp section with a much better two tube preamp section.
The Puccini Settanta uses a typical SS amp section w/ a SS preamp section, with a different sound.

The magic of the Primo, Cento, and Verdi is the LM3886 powerpacks. Do research on these National Semiconductor gain cards and you will find that they are awesome chip amps and contribute to its warm, fast, and dynamic sound.
