Here's my decision. I've put together a really great sounding little rig. F1-X into either a Stew 1.2 or PV 1400X into Bergi Ht112/EX112. I really can't decide which power amp to get. The rack I'm using has a computer fan mounted in the back that should help keep a little Stew cool enough at 4 ohms but, the PV has a built in fan. Is the cooling fan the only real difference between these two fine amps. The cost is almost 2 to 1 with the PV being over 1000 (new) and the Stew at about $550. Which one would you get? The Dynacord in the pic won't bridge into 4ohms and is only 250 watts into 8 ohms bridged. It works fine with one Bergi but just won't cut it with 2.
