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?  .

McIntosh MA 352 - Hybrid integrated amp 200 W.  I traded in my MA 6900 for it.  Reg $6,500. New model.

@jasonbourne52 i am using Topping D90 AKM 4499 DAC (warmer than ESS 2nd edition D90) from Auralic Aries Mini to Krell via balanced XLR .

I believe Topping PA5 is more suitable for desktop monitor speaker ,  I prefer musical and warm sound.

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