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.
- 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.
- 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.
