after listening to different hi end setups using among others, Raidho, Rockport, Martin Logan, Reimyo, Gryphon, Wadia, things were just too hyper-realistic for my taste, (although the latest Reimyo solid state amp in spite of being mated with speakers not of my taste, did leave me thinking how to come up with the $$$) .
have not been able to hear either the PS or Hegel and after letting my rig cook continuously for a few days, I was quite content with what I had (dated and all) and ultimately lost the itch.
concerning downsizing, an integrated would be even more practical than a stereo amp as far as saving space but I´d hate to ditch the xp20.
