Audio Power Labs 50 TNT Class A Triode

These are highly advanced vacuum tube amplifiers built to a cost-no-object design objective. They include a highly advanced switch mode power supply for amazing bass control and weight as well as permanently sealed liquid cooling. The parts quality, the circuit, and the execution are all first rank.

Moreover, the exquisite Art Deco chassis made of high-grade aluminum and polished glass was designed to manage vibrations while being aesthetically pleasing in the vast majority of setting.

Sonically, the only superior vacuum tube amplifier in my experience is the Berning 845 OTL amp at $75k.
