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 ?

I'll try...but my local dealer told me to not push the tubes to hard..and that the powers needs to get the signal to amplify it...so i will run like 12-14h a day unfortunately. Do you think i can run it with the powers switched off ?

The 160.5´s are in.... yhaaa ! The 600.5 are also here, so I have had some very interesting evenings. The 160.5´s have only had about 60 hours of burn in so far. The 600.5`s are pre owned, so they are in a ready to rumble state.
My impresions so far, are that the 160.5´s sound sweeter by a small margin, but the 600.5´s have better low end control and slamm. Thy are deffenetly brothers.... the over all tonallity is the same and the X 600.5´s are sonically very close to the XA´s.
But I will have to say that I have also compared the Pass amps to the MSB 202 monos I have been playing on for the last 6 months, and so far they sound better ower all. First and foremost they are more neutral to my ear. They sound more airy in the top end, and imaging and body is better than the XA´s even. There is no doubt that the 600.5 has more brute power, but they sound like a welding machine in comparison ( = less finess ). It might be that the XA´s will surpass the MSB´s when they get more burn in time, but so far it seems to me that MSB are the winner.
There is also something about the timing of the MSB´s that surpases the Pass amps.. very hard to explain, but the timing is very "natural" and organic. A bit like the sound of the Atmasphere OTL amps, if you know what I mean.

I will get back when the 160.5`s have had more time to settle.

Hi Johnb30

i would have thought if you run signal on infinite repeat thru preamp with power amps off, that should be fine.
