I am curious if anyone can give me any good feedback on soundstream rubicon 600-4 and xtant x604 amps i have run eclipse before and was pleased but have found good deals on the other amps and can't find any real good deals on the eclipse the reason i am asking about those amps is they are roughly in the power range i am looking for 75 to 100 watts rms/by4 and are there any other amps out there that would compare sq and build quality wise to the eclipse for around $200.00
