Know before you buy
This feature allows you to change the amplifier's sonic character on the fly using the remote. Triode mode offers a warmer, more intimate sound, while Ultra-linear mode provides greater power, punch, and a more expansive soundstage.
Adaptive AutoBias eliminates the need for manual tube biasing, which is often a tedious and technical process. It continuously monitors and adjusts the tubes to ensure they operate at their optimal point, which reduces distortion and significantly extends the lifespan of your tubes.
Yes, the unit includes a dedicated, transformer-coupled subwoofer output. This allows you to integrate a subwoofer into your system seamlessly without compromising the signal integrity of your main speakers.
If a tube fails or reaches the end of its life, a small LED light will illuminate directly in front of the problematic tube. This takes the guesswork out of troubleshooting, letting you know exactly which component needs to be replaced.
The headphone section is a dedicated, transformer-coupled circuit designed to drive a wide range of headphones effectively. It utilizes the amplifier's main power tubes to deliver a rich, detailed sound that outperforms many standalone headphone amps.
Point-to-point wiring avoids the use of fragile printed circuit boards, which can degrade over time due to heat. This construction method is more labor-intensive but results in a more durable, reliable, and better-sounding amplifier that is easier to service in the long run.
