Amps for Sonus Faber Stradivari Homage

I have a pair of Stradivaris that I love, but I´m having a little trouble finding the right amps for them. My system consists of: Emmlabs CDSA SE latest version, Clearaudio Champion Level two/ SME V/ Benz Ruby, ARC REF3, MSB 202 monos.
I have driven the speakers with a set of Pass XA 100.5 before, but they sounded compresed quite quickly. The MSB´s offer more power than the 100.5´s and sound more detailed and airy, but also leaner and brighter.
I love detail and air, but I also crawe bass slam and body in the midths and highs. I absolutly hate lean and bright sound, no matter how detailed it might bee.
I have owned quite a lot of Krell gear in the past. I liked the bass of the ols stuf like the KSA s series + the first FPB stuff. The rest of the frequency range however, sounded rough and "solid state" to me. I liked the detail of the MCX 450´s, but they sounded to lean in the low frequences to me. I have tried tube amps as well, but I have not yet found a pair that did´nt sound like tubes in the bass region
So I am dreaming of a set of amps that delivers a full bodied, warm but detailed sound with bass slam and bass detail as well.
Any recomendations ?
NB: English is not my native language, so I hope for your understanding if my spelling is off !
My friend uses Nagra VPA tube amps on his Strads and it's quite nice.
I'll second the McIntosh recommendation, either 501s or 2301s. Wonderfully listenable and can really jam when called to do so. Burrmester 911s in monoblock configuration also do very well.
Anybody heared the Jadis JA200 monos on the Strads ?
Hi 0461.

I owned STrads for a number of years, but i have not heard them with Jadis...however, i have heard the Strads with a number of different tube amps (2 CJs, ARC Ref, Pathos, Unico) and have not been disappointed once. Based on my experience, I would definitely be prepared to bet it is a remarkably good sound in the areas where the Strad is strong - voices, spaces, life, musicality. I do not know the Jadis and their ability to control bass...despite the bass on Strad being very good, it responds extremely well to high current to control its drivers.

Good luck and please report if you hear them. even though i no longer own the Strads, i would be curious to know about how well they pair with Jadis.
Jadis is a good idea, can can listen to them naked...pure tone will touch your skin :-) another excellent sounding amps are the old Jeff Rowland Model 8 and 9
