The best preamp in its class just got better! By incorporating the best elements of the critically-acclaimed ProLogue Three, plus many of the ground-breaking features from the more advanced DiaLogue Series, the next generation ProLogue Premium Preamplifier sets a new benchmark for tubed preamplifiers using the following features:
*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.
As with all PrimaLuna components, the ProLogue Premium Preamplifier 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, Swellong, 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.
Incorporating the best electronic elements of the original ProLogue Three, plus selected ground-breaking features from the more advanced DiaLogue Series, the next generation ProLogue Premium Preamplifier is an engineering marvel — setting a new benchmark in high-performance audio with the following features:
*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 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.

*Point-to-point wiring and premium parts including ALPS Blue Velvet potentiometer, Solen and Swellong capacitors, ceramic tube sockets, gold plated RCA jacks.
*Tube rectification using two 5AR4 tubes, one for each channel. Designed with no cathode followers for a vibrant midrange, creating a three-dimensional soundstage rarely encountered.
*Low noise achieved with DC heater supply and 12 dB of gain. The power supply is perfectly de-coupled with an ultra-wideband, constant source impedance, and low corner frequency of over two octaves below the audio bandwidth (4Hz).
*Non-inverting and has two pair of outputs so you can easily bi-amp or add a powered subwoofer. Fixed tape out included for recording, or adding an external headphone amplifier.
*Hand-rubbed, high-gloss finish with black or silver faceplate and quick-release tube cage.
