LINER NOTES

The AQ1001DT was dead quiet, with no annoying hissing to be heard from my speakers. It sounded warm, textured, smooth, and dimensional, and was a good match—although not a great match—for my soft, lush-sounding Dali Grands and Arcam CD player. It would probably sound awesome in a system that is slightly leaner than mine. The Margules that I reviewed earlier is in the same price range, but I would pick this amp every time. Although the Margules was more flexible, the ASL sounded better in my system.
