Integrated Amplifier with the Good Bass and Extended Highs


Looking for an SS Integrated amplifier with the NAD's or Simaudio's deep bass but with the extended highs
for the PSB Synchrony speakers. I listened PSB with the Accuphase E-470 (which I shouldn't) and since then I can't find the right amplifier. I tried Belles Aria but I didn't like the bass.

I am curious about Wells Audio- have any of you guys taken a test-drive?

Happy Listening!
THANK YOU ALL FOR YOUR OPINIONS
List of the amplifiers:
Accuphase E-270 (new) Hopefully similar sonic signature as the E-470
Simaudio 600i (used)
Hegel H160 (new)
Which one?


I had read  great stuff about the Aria. I use Belles Soloist 1. You really have picked great gear, just now personal preference and system/room synergy. Maybe also speaker placement.
