After a lot of research on Power Amps, I decided to go with a Crown CE1000 for my Tempest based sub. After experiencing the fan noise, and the 1.4V input sensitivity that is difficult to drive I am looing into other options to see if I can solve those issues. I first thought about getting two plate amps and building a rack mount chassis for them(I need a rack/shelf sub amp with level control). But I keep getting recommendations for these Ausiosource Amps. I always thought Audiosource was the "cheap" brand that Best Buy carried, but based on recommendations and reviews I have read this seems to not be the case. After reading all the near perfect reviews of these amps on audioreview.com, these amps have sparked some interest. Many of the reviewers are comparing these amps to much more expensive ones such as parasound, etc... Now they also state they are not Krell quality, but what amp this cheap is??? With the price being just right, has anyone had experience with these amps? What is the quality like? The amp will be used for subs only so mid/high sound quality is not an issue. Also, how would they compare to pro amps such as my entry-level crown? Thanks all!
