    Product Description


    The all-triode REX II power amplifier represents a technological tour de force of modern engineering applied to vacuum-tube power-amplifier design. From the plug-and-play simplicity provided by its auto-biasing and electronic protection circuits, to the palpable illusion of recreating the original musical event in your home, the REX II combines high-power output, beautiful midrange texture, and great extension at the frequency extremes. Delivering a robust 80 watts per channel in the stereo version or a compelling 160 watts per channel as a monoblock‚¬?and fully symmetrical from beginning to end‚¬?it is a design without compromise.


    Think of the REX II as two single-ended amplifiers per channel, with their waveforms summed at the output transformer.No direct current flows through the latter, allowing the output transformer to be a truly wide-bandwidth design while reducing low-frequency distortion. REX II extends the benefits of vacuum-tube current sources to include both the first and second gain stages of the circuit design. Hence, the linearity of the gain stage improves, the adjustments for the first and second gain stages become independent, and the tube current source components operate at a lower stress level. You can also fine-tune the sound to best meet your individual needs.


    The REX II‚¬„s advanced design eliminates the constant need to set and readjust the proper bias of the output tubes.An intelligent automatic bias circuit adjusts for changing line voltage and aging tubes.For convenience, LED indicators show the status of each individual output tube. BAT further extends the plug-and-play nature with a novel ‚¬œfuse-less‚¬? protection circuit, which eliminates the power-supply rail fuses to provide both a more refined sonic performance and user-friendly experience. All you have to do in the event of an output tube being over-stressed is to flip the power switch. No tubes to bias. No tube fuses to replace.It doesn‚¬„t get any easier!
