Recommended integrated amplifier for upgrade


Hi, i am searching for suitable integrated amplifier to match/pair with my Sonus Faber Concertino Domus, my current integrated amplifier is Krell KAV-400xi.which is about 15 years old.

My sound preference is towards slight warm, wider stage with music genres of jazz, classical, new age music, and few jazz vocals.

Shortlisted few integrated amplifiers like Accuphase E-280, Luxman L-505uxii, McIntosh MA5300, 

What is your recommended integrated amplifier which is 'best pair' to provide Sonus Faber house sound?  .

@auronthas, not familiar with your speakers but seems they are 4 Ohm jobs. As such, I would be very wary of the MAC MA5300. Nice amp but not sure its power supply is up to the task with those speakers. It'll drive them OK, I think, but not sure it will really make them sing. I've done serious seat-time with the MAC MA5300 and the Moon 340i that overthemoon mentioned. I'd recommend you check out that amp paired with speakers as similar to yours and/or 4 Ohm nominal load speakers of similar sensitivity to see what you hear. In short, if  you are considering Class A/B amplification for those speakers, you should listen to stuff that has a robust current supply.

I run a MA5200, the predecessor to the 5300 in my office system and it has run all the speakers I've connected to it just fine, including Concertino's and Concerto's from SF.  The Luxman, Accuphase or the McIntosh the OP listed would be great.  Just flip a 3-sided coin and pick one. 

+1, As was suggested above, the Ayre Acoustics AX-5 Twenty amp is excellent. BTW, there is an Ayre AX-5 Twenty amp listed for sale on Audiogon.  Please see:

Another less expensive alternative is the Ayre EX-8 2.0 integrated amp. Please see this link:
