Wilson Sabrina X ... oh my God! and Jadis... or?

@newton which principal was this as I tried it for 3 weeks and returned. Didn't have enough meat. Mimas is much better. 

I own SabrinaX speakers and use VTL tube amp and pre-amp. Have a Ayre CD player w a card to use it's DAC for streaming. I've been listening to high end systems since the early 60s when my dad had BIG Bozak speakers and Marantz tubes. I prefer listening not-loud, but loud enough that my ears start ringing after 2+ hour sessions that take me out of this world. To quote my friend (who owns SashaDAW's w a ConradJohnson amp) my system sounds "F---ing glorious" and I agree. My room is decent sized, but not big - about 15'x16' with a funky ceiling. I auditioned lots of solid state amps and none were remotely close to the VTLs. The amp has a switch in back to toggle between lower and higher power modes. Honestly, I think I could fool experienced listeners with an A-B comparsion, it's hard to differentiate. Surprised these can sound great w/o the power you'd think is necessary. BTW, speaker placement and sound treatments are very important. 

For a limited budget, my Wilson dealer recommends the Michi amps (Rotel's high-end amps). The list includes the S5 (500 wpc) and the X5 and X3. I heard the X3 with the Sabrinas last week and it sounded very nice. 

Just to make everyone jealous, I had a once-in-a-lifetime opportunity to hear the SabrinaX at the Wilson factory last week -- driven by D'Agostino mono blocks, dCS Streamer, and dCS DAC. I've heard many systems and have been to several audio shows, but that was the most spectacular sound I have ever heard. Period! If you have $200k for electronics (wink, wink), I highly recommend this gear!

riche569 -   On another board a Wilson Audio principal mentioned that the Audio Research i50 is a very special (read excellent) match with the SabrinaX.

A little birdie tells me that SabrinaX and the new ARC i50 Integrated is a match made in heaven.
 

Looking at the comments above, VAC does not sound solid state.  It is a modern tube sound so it won't sound flabby, but is not sterile.  Bigger concern is the miserable impedance values based on the measurements I have seen for Sabrina X. Min impedance is 2.43 ohms in a beefy part of the frequency range. This is not a good profile for most tube amps.  

I would look at amps that can deliver current which will give you the cleanest, clearest bass response.  This tends to be SS but some tube designs will work.  

I have no idea what your budget is but the AVM Ovation 8.3 is amazing with a tube input stage and oodles of power.  I have people driving a lot of great speakers and it is a GOOD match for the Sabrina X.   

Naim is a nice match.  Top line power isn't huge but Naim products basically thrive at 2 ohms and will handle the impedance issues well.  You would need separates but at least they have stopped with the stupid DIN connectors and moved to XLRs.

AGD would be brilliant as it is capped more by your home breaker in terms of current draw than by the amps power supply.  Efficient and sweet sounding, this is my go to when folks are moving away from tubes but want to maintain a liquid sound.  Separates again though but all extremely small components.    

The other really interesting integrated would be the Riviera Levante.  30w in Class A, 150w Class AB and a tube input stage.  I had someone move from a VAC Master Preamp and Allnic Monos and they did not feel this was a step back as they downsized.  

Octave with the Super Black Box will do the job well.  Tube choice really matters though and I would need to check with my rep to be reminded of what he suggested.
