Wilson Audio Sasha 2 vs Sophia 3

Thanks again, George. 

I do know that my ARC does not increase/decrease W according to impedance/ohms.  

I should have my Sasha's here in the next week or so.  It will be quite the comparison; going from very efficient and quite easy Focal 1027S to the Sashas.  I don't think the Focals have pushed my amp much, but I expect the Sashas to lay it out.  
I know the Sashas can do much more - in the bass for example - than my Focals.  Something like ~15 Hz lower or more before -3db, for example.  I'm not sure if the little VSi60 (KT120s) can power up the Sashas enough to be a significant improvement over the Focals, Or if I'll need much more amp to hear real gains.  
My guess is: The Sasha's will sound much better than the Focals, immediately, all around, but they will still be far from giving me their all with the VSi60.  

Next step is a step up in the ARC line via separates.  

Thanks again!

Wow! Where were you guys on my best headphone thread?? Wilson, Levinson! True dyed in the wool audiophiles! While I'm here, looking for Levinson 535h amp! Used if possible! Thanks!

It's been awhile, but figured I'd do a brief update in case anyone stumbled upon this. 
System is now:
Sashas
Ref 3 pre
Ref 75 amp
Lumina T1
Transparent ultra cables

@georgehifi I've really enjoyed the system with the 75 for a year.  I did drop in a SimAudio Moon 860A just to see what the Sashas can do with more power.  It exposed, as you produced, much more to the recordings.  But, over all I'm a tube guy, and prefer my 75 over the bigger Moon.  Having said that, I'm considering moving up to the ARC 150 now to get a bit more base grip on the edges without (hopefully) giving up all the rest - which is perfect for me.  

I owned a pair of Sophia 3's for five years and are very familiar with the Sasha's. The Sophia's are much closer to the sound of the Sasha's vs the Sabrina. However, the Sophia's are a lot more easier to drive than the Sasha's and work a lot easier in acoustically challenging rooms than the Sasha.

Thanks! for the update- jo1mtb

Happy Listening!
