A modern marvel with vintage flair. It’s well established that tubes do something for the midrange that transistors have a difficult time with, bringing a natural warmth that’s very pleasing to the ear. This unit had a few issues we solved by replacing some problematic components. After adding all new hand-matched tubes, she sings beautifully. If you're ready to dip your toes into the world of tubes, here's the pool.

- 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.
