I used to love integrateds:
went along those lines:
Perreaux i150 (early model with Audiostatics)
Bow ZZ1
Krell iL300
then a step up:
Einstein light in the dark (OTL based on mosfets, changed to Merlin vsm mxe by then)
Accuphase E550
Pathos TT
Both of those two are absolute wonders in sound, I could imagine that the Inpol2 ist an amazing amp, as both Accu and Pathos did run a bit out of steam..
Since then I moved to Berning,that does it for me, but its not strictly integrated ;-)
