The highest rated stereo tube amp in its class just got better! By incorporating the best elements of the critically-acclaimed ProLogue Fourand Five, plus many of the ground-breaking features from the more advanced DiaLogue Series, the next generation ProLogue Premium Series, is an engineering marvel — a single, power amplifier that sets a new benchmark in high-performance audio with the following features:
- Innovative, new Adaptive AutoBias circuitry. By simply flipping a switch, users can re-calibrate the amp for optimum operation of EL34s or KT88s. Every ProLogue Premium Series amplifier can be ordered with either set of power tubes installed. And remember, this circuit continuously monitors and adjusts each tube to run in its sweet spot. No biasing—ever!
- New output and power transformers. Modeled after those in the DiaLogue Series, these heavy-duty, high-efficiency transformers offer better control over challenging speaker loads, as well as increased detail and musicality.
- New front-end circuitry. Optimized to use two 12AU7 tubes per channel. With the improved transformers, produces lower distortion.
- Zero negative feedback - as with the ProLogue Series power amplifiers, the ProLogue Premium Power Amplifier uses a zero negative feedback topology for greater tonality and better overall musicality.
- Conservative design parameters: Though PrimaLuna amplifiers are powerful, tubes run well below their maxim ratings.
Next, the ProLogue Premium Series introduces four innovative circuits that protect the amp at every level:
- BTI-circuit. BTI stands for "Bad Tube Indicator." On the chassis’ deck in front of each power tube, is a small LED that lights up if the tube goes bad. This circuit works hand-in-hand with the new Adaptive Auto-Bias circuit.
- PTP-circuit. If the power transformer should overheat, this "Power Transformer Protection" circuit cuts primary power, allows the amp to cool down, then resets itself.
- OTP-circuit. The "Output Transformer Protection" circuit protects the output transformers in the event of a massive tube failure or user error.
- +B relay. Replaces the plate fuse and works in conjunction with the OTP-circuit to protect the amp against tube failure. This method is less intrusive sonically and the relay resets itself once the faulty tube is replaced.
As with all PrimaLuna components, the ProLogue Premium Stereo Amplifier is made by hand with the finest point-to-point wiring and quality equal to—or better than—any product you can buy at any price.
Built using premium parts featuring: ceramic tube sockets; Solen and Nichicon capacitors; WBT-style solid core speaker terminals; ALPS Blue Velvet volume control; gold-plated RCA jacks; toroidal power transformer. All packaged in a high-gloss, hand-rubbed finish.
