Class AB, 4-Ch — Power 2Ω: 4 x 275W, 4Ω: 4 x 150W
The AP Difference
- The same high-end audiophile electrolytic caps as the flagship LX amps, with WIMA poly caps in the signal path.
- A new low-noise input op-amp and the smoothest available op-amp in the signal path.
-
Doubled output drivers with increased operating voltage; a new aerospace insulator pulls heat off the outputs faster.
-
0.1% precision resistors at the differential input stage for the lowest possible noise floor.
- Patented multi-ground, gold-plated RCA connectors for perfect signal transfer.
- Low-noise gain pots with detents; matt-black finish with an engraved solid-copper serial plate.
