Thanks everyone. Thanks Ivan, for such a great site!

Pass Labs + Wilson is always a good combo. heard it a few times & it shines very well.

My friend drives his Sashas with XA200.5 monos and it's a wonderful combo.

Sasha"s with Pass Xa200.5,it must be magic:banana::banana:. Did your friend compare them with other great amp? Which preamp does he used???

+1 on the XA.5 series and wilsons... prior to going all tubed (VAC) that was the best sound i'd attained.

Down Under
 

I have been using the X260.5 monoblocks to drive the Sashas with ease.The much feared low impedance in the bass region is a doddle.The James Blake track Limit to Your Love which has fearsome bass pedal on Lp shakes the house without troubling the amps at all.
Is the treble sweet? I have found it to be free of harshness and the midrange quite spellbinding.
Worth a try or at least an audition.Like everything else make sure they have at least a weeks worth of use before dismissing them.

Interesting... Too bad that VAC brand is so rare here in Europe. I think it can be found in Belgium, possibly. Jean-Paul, try it :banana:

if you're not averse to tubes, VAC amps and wilson's are the best my rig has ever sounded!

As I see XP-20 & XA-100.5 is considered as a good match for Sasha which is not the easiest thing to drive.

Going step down to Sophia-2, would XP-20 & XA 60.5 make it as matched as XA100.5 for Sasha? In other words is there a point in spending extra $ on XA100.5 if its advantage of XA60.5 would not be noticed by the Sophia 2?

Just got a pair of Sashas to replace my B&W 801s and am driving them with Pass X0.2 preamp + X600.5 mono blocks. The sound is amazingly dynamic, transparent and detailed. Great combination.
