Simplicity and sound quality
Pictor is an elemental version of our acclaimed Performance Series Virgo III line stage. It uses the same core circuit topology as Virgo III, and a few minor changes aside, the same separate power supply. The main difference is that Pictor has fewer inputs. For simpler systems, Pictor is the perfect choice: simplicity and sound quality distilled into a single product.
As with all of our preamps, Pictor uses our Line Stage Gain Module, a unique design that uses a servo circuit to monitor and maintain the balance between the positive and negative halves of the audio signal. When Pictor is used with a Constellation power amplifier, the Constellation Link may be employed, maximizing sound quality by bypassing the power amplifier's gain stage.
Pictor mirrors Virgo III's convenience and refreshingly simple design. A front touchscreen with elegant, easy-to-read fonts accesses all adjustments. Frequently used controls are also available on a machined aluminum remote. A home theater bypass mode is provided for seamless integration with surround-sound systems.
Triple-transformer, separate power supply
Pictor's power supply resides in a separate chassis made from machined aluminum slabs, connected to the preamp section by three high-current PCOCC cables tipped with Hypertronics connectors originally developed for aerospace. Keeping the power supply seprate shields the audio cirucitry from the electromagetic fields generated by the transformers.
Inside the chassis are three separate power supplies, one each for left channel, right channel and control circuits. This dual-mono design provides separate R-core transformers for left and right channels. Thus, extreme demands in one channel do not affect the other, so the music is reproduced with all the natural imaging and soundstaging of the original recording. A third EI-type transformer powers Pictor?s control circuits.
Our optional DC power filter augments the already impressive power storage and filtration in the stock power supply. The added peak output and filtration from the DC filter allows Pictor to achieve even better dynamics with even lower power supply noise.
