BEST AMPS FOR WILSON SASHA

i am running Sasha wit Xa 100.8  and beginning to think I need more power .  Bass needs more impact and midrange more projection.  i am looking at the Burmeister 911 mk3 or Xa 160.8

Thank you David. i recently installed Furutech GTX D NCF R.  An improvement over  the Oyaide R01.  will the Synergistic Research be better?

thank you Charles .
 Hoping for other Sasha owners who tried either of OP's 2 amplifier choices to share their experience.  I would imagine a few  Audiogon members have Wilson / Pass Labs combination, and either have not seen this thread or busy at the moment.
Maybe Charles does not have the opportunity to audition these amplifiers with his speakers and relying on opinions.

I am patiently hoping somebody (singular and plural ) could answer the original question precisely and in a manner that would settle the issue for orionpcgames.  Allow me to repeat his question "hi, i have in this moment a ayon cd5s cdplayer with built in preamplifier , pass x250 amps and wilson sasha speaker ( i love sasha), i want a new and better amplifier, the options are two, pass xa100.8 monoblocks or cary 211fe monoblock, what is the better option for the sasha?, your opinion please"
and i would also benefit

orionpcgames.   What amp did you finally purchase for your Sasha.
