Amp / Pre-Amp for Sonus Faber Serafino

This is what the OP wants (warm) and what is the right amp for his speakers to drive them to what they’re capable of, and sorry that doesn’t include Mac’s.
I’m sure having this caliber of speaker $33K aud he doesn’t want them compromised with inadequate amplification.

Serafino bench measurments:

Impedance phase angles at LF means that the Serafino’s minimum EPDR (equivalent peak dissipation resistance) is 1.9ohm at 272Hz, 0.2ohm higher than the Amati’s.

Thanks everyone for your suggestions. Appreciate everyone's opinion and knowledge. I hope, i did not start a debate here. I am sorry if i am responsible for the confusion here.

I have been listening to music for more than 2 decades and started using professional audio equipments only since 2017. I am happy with the music quality i am getting in my existing system (Marantz + PrimaLuna Prologue + Martin Logan), placed in a small room.

We moved to a new home few months back and the new speakers (SF Serafino) will be kept in the living room (40 ft long and 20 ft wide) (larger room). The living room interiors have been chosen with the acoustics in mind.

My music preference is Jazz and Classical on the western and tons of Indian classical (variety of instruments and vocals).

An example for my preferred music would be (sorry for posting the songs, if that is not required / inappropriate)

I would like to get the best out of SF Serafino for the music i listen to.

Thanks again...

CORRECTION

I stated above I never heard a Krell I liked, but it isn't so.  I once was loaned a 50wpc Class A Krell in the early 90's time or so.  The amp was warm sounding with a lot of oomph behind it.  I had forgotten about that amp.  If I had the dough at the time I would have bought it.  I was using a Classe' amp at the time.  Sorry for the confusion.

In that case, you may want to try D'Agastino Momentum M400 Monoblock amplifiers. They not only sound excellent but will also add a lot of "sparkle" to your listening room. I've heard them paired with the SF Aida speakers and the sound was truly exceptional. I think they were paired with Audio Research Reference6 preamplifier but I'm not sure.
Good luck with your search.

True they would be nice also, but the price for the OP is way too much compared to say the Gryphon 120 or 300, and I’d say they would be warmer sounding as well which he wants..
