This highest level of resolution and musicality has been accomplished in large measure by all-new audio and power supply circuits, incorporating tube rectification (via one 5AR4) and tube regulation (via one 6L6) of the power supply (also packed with the newest Infinicaps, and one 6922). Gain is provided by eight selected 6922 twin triodes, like the REF1. Redesigned toroid transformers also contribute to improved dynamics.
Mechanically, the REF2 is almost identical to its predecessor, with one significant exception: the input selector now offers a unity-gain A-V processor pass-through, allowing easy incorporation into video systems for both stellar music performance and convenient gain control via the processor's master level control when desired. Now, you can easily have it all in one flexible system. Importantly, the REF2 circuit also effectively prevents any possibility of input-signal overload while preserving incredible sonic purity.
Chassis configuration and size, front-panel controls (with the exception of the processor-input labeling) and rear-panel input / output configuration are identical to the REF1. A total of eight balanced and single-ended inputs are provided, plus two sets of main outputs and record out. In addition, all front-panel functions are accessible from the included remote control. Because of this mechanical similarity, REF1 owners will be able to upgrade their REF1 units to full REFERENCE 2 configuration, complete with new 3-Year Limited Warranty. This is not be an inexpensive update, as the original model is essentially taken apart, then reassembled using new audio and power supply boards, two new toroidal transformers, new front and rear panels, and all new vacuum tubes. MSRP of the factory upgrade is $4495, plus shipping to / from the factory (no field update kit available).Description:
