I happen to have a pair of ASL AQ1006(845) monoblocks. They sound absolutely wonderful. They are built very solid. I have the anodized black-faced units. These amps sound so good, I listen for HOURS on end!!!. The company is very consumer-friendly and will assist you with your decision regarding component compatability. Very good warranty. Also, ASL has been awarded the Golden Ear Award from a prestigous audiophile magazine recently for the 1006 monos.
