*New power transformers. Heavy-duty, dual-mono, power transformers increase control and detail. Addional windings were added to each transformer for improved synergy with the optional PhonoLogue MM Phonostage. The preamp weighs in at a substantial 37.5 pounds.
*Home theater pass-thru. Straight from the critically-acclaimed DiaLogue Series, this direct-line circuitry means less noise and coloration over unity gain circuits.
*New front end circuitry. Optimized to use two 12AU7 tubes per channel. Combines with the improved power transformers to further lower distortion, dropping by a factor of 20 at output levels above one volt! This in turn dramatically improves sound quality.
*PTP-circuit. If the power transformer should overheat, this innovative "Power Transformer Protection" circuit cuts primary power, allows the preamp to cool down, then resets itself.
*Full-function remote. Slim, anodized aluminum remote, controls volume, mute, and source selection, as well as Play/pause and Stop/eject functions of the new ProLogue Premium CD Player.
