i fully second the original poster and i confirm: the SSL X Comp is totally unique with beyond OVERKILLING and unique capabilities of processing sound, NO WORDS can explain the what it does, you really have to try it and hear it on your own.
also, as speaking strictly within the domain of SOFTWARE/DSP POWERED processing filters, and from everything i own and i have tried out (waves, tc, uad, psp or whatever is out there) NOTHING is ever comparable to the SSL X-Comp (could have been even said it is issued from alien technology, who knows? lol )
its gonna be certainly the future legend of the new virtual/digital music ages.
i got 9 precious hours of demo time left on mine..
im fine with this SSL X COMP PRAISE POST because i understand the what experienced the guy who started this post
