Ok, my US acoustics amp was lost by UPS, so now i am looking for something else. Found these eclipse amps for pretty cheap on ebay. This amp will be powering DLS R6A's (80 watts RMS). I am still looking at the soundstream rub 300-2 as well. The 3640 will do 120 x 2 at 4 ohms. I can't seem to find anything on the 3322 other than it does 160 x 2...but i don't know at what ohm load. The rubicon does 75 x 2 at 4 ohms. Go ahead and list other suggestions that are cheap.
