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 !
i've the Nagra VPA on my Stradivari and they're superb,also i tried the Gryphon Antileon stereo also they're great
I have a mcintosh mc402 now playing on the Strads, but will probably go back to my Mcintosh 2102 when I re-tube. The Strads sound best with my tubes. I just put some Telefunken smothplates in my Pre, C220. The 402 plays louder with more control. The tubes provide more midrange magic, IMHO.
Hate messing with tubes though.
I have the Strads hooked up to Mcintosh MC2301's and rotate between the Jadis DA60, VAC 300.1/Sigma 160i and MC601's. Cabling is Nordost Valhalla/Odin and I also use Kubala-Sosna Elation. Your welcome to come by for a demo, we are located in the Miami,Fla area just minutes from the airport, I am a dealer for all of the above mentioned brands.
Watching this thread with interest. Running a MSB DAC with B&W 803D's and have both the 202's and XA100.5's on my short list. Pre might end up being either attenuator to DAC or the likes of REF.3/LS5/CT5/XP20. Interested to hear how the 202's compare to the XA's after suitable break in.
Hi Doug2507,

After having listened to both the Pass and the MSB´s for a few months now, I must say that MSB is the owerall winner for me. They do everything better, except for midrage warmth perhaps. But if you end up going for the MSB´s, make sure that you get them in the latest version because the earlier models can fail. But if you buy them new today, they will be allright I have heard !
