HEllo, I'm trying to find a single rack space power amp. . . used a Stewart, and was dissappointed at the performance. It would shut down periodically due to heat, and I ended up using a 3 rack vented case which defeated the purpose of a single rack amp. The Stewart died prematurely. Recently, I installed some Camco vortex 6 amps now distributed by Ashly in a PA setup, and they are working great for driving Nexo subs. This has re-instilled faith in class D amps. Has anyone tried one of the Powersoft Digam amps? http://pro-audio.powersoft.it/an_series_list.php?use_in=53&id_menu=271&id=2 I've not been able to find pricing on them yet. I'm driving Acme B2 8 ohm so I'm needing something that will bridge with an honest 600-1000 watts.
