Conrad Johnson Premier Act 2 Tube preamp with remote

Good day. I bought this unit from the original owner and the age is about 6 years old. I have the original box and packaging and really like the sound of this preamp but need to sell off my toys due to a major home repair needed. This is definitely a reference line-stage preamplifier and this preamp incorporates the breakthrough concept of the composite triode circuit (which has garnered more than a dozen international awards for conrad-johnson preamplifiers). The ACT2 refines this approach by implementing circuit upgrades and by taking advantage of recent advances in materials technologies. The ACT2 Preamplifier is a vacuum-tube, line-stage preamplifier that features input selection and level adjustment by microprocessor-controlled relays. Level and balance can be adjusted in 100 steps of approximately .7 dB per step. All functions can be controlled by the hand-held wireless remote control.
The audio circuit consists entirely of a single amplifier stage incorporating one composite triode comprised of four paralleled sections of ultra-high transconductance miniature dual triodes. This arrangement achieves a low output impedance while reducing the number of active stages to the absolute minimum of one, resulting in unparalleled sonic purity. DC voltage is supplied to this stage by cascaded discrete voltage regulators that absolutely isolate the audio circuit from the power line by maintaining virtually zero impedance across the audio frequency band. Infrasonic noise is minimized by operating the tube filaments (heaters) on a dc voltage supplied by another discrete regulated power supply.

Considerable care and attention have been paid to the physical aspects of the design as well. Microprocessor controlled relays, used for selecting sources and level setting, are located right at the input connectors, keeping signal paths short to minimize crosstalk between channels and inputs. Critical audio circuitry is mounted on a subchassis that is isolated by a suspension system designed to minimize microphonics. The dramatic casework features an attractive clear Lucite tube guard outside the chassis, allowing for easy access for tube replacement.

Each part for the ACT2 has been selected on the basis of both sonic performance and durability. The audio circuit (including the level control) is executed entirely with precision metal foil resistors and Teflon and polystyrene capacitors. Tubes have been carefully hand selected for minimum noise and microphonics. The dc regulated power supplies use the same quality resistors as the audio circuits. Capacitors for the power supplies are exclusively polypropylene, polystyrene, and Teflon - there are no electrolytic capacitors in the audio circuits or their related power supplies. Switching relays are sealed and have gold plated silver contacts. Input and output connectors are machined from oxygen free copper, and are gold plated. The ACT2 has achieved a new standard in musical performance and it is built to last.
