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?  .

Leema Acoustics Tucana II - exemplary sound, richer and less technical than Luxman 507uxII

 

Too clean, too analytical, it sounds dry thus boring and fatigue over time. Thus, prefer slight warm, analogue and musical soundstage.  I was thinking about tube hybrid amplifier but it could be too warm and need maintenance on tube or tube rolling … 

I have a Luxman 505uxii paired with Dynaudio Special 40s and a REL sub. Absolutely love it---friends that stop by can't get over how rich, warm and detailed they are. You can't go wrong with a Luxman. Just my 2 cents. Good luck. 

I had a PrimaLuna HP w/ SonusF Guarneri’s. It was a tad underpowered. Replaced w/ a Rogers HiFi KWM 88 and am very happy. I’d consider massive seperates as the next step up. As EBay takes 12.6% using the phone to the mothership you could negotiate that from the price. It’s a monster of a class A amp. 

PS Audio makes great stuff. 
 
Budget? Rest of system? Room?  Roon?
