Antique Sound Lab AQ 1001 Mk.II

The Antique Sound Lab AQ 1001 Mk.II integrated amplifier ($1995) did a fine job of driving Reference 3A’s Grand Veena loudspeakers to concert hall levels. The AQ 1001 Mk.II is rated to deliver 50W in pentode mode and 25W in triode mode, and offers manual bias adjustment for each tube. The latest incarnation of this long-standing design incorporates new output transformers with no negative feedback and a choke-regulated power supply for “a faster and more dynamic sound,” Reference 3A’s Tash Goka told me.

Though it doesn't include a phono stage (bummer), the ASL AQ 1001 is a hefty-looking tubed integrated at a not-so-hefty price.
