Power supplies are hardly new territory for AVID, using them to great effect within our turntables and phono stages.
So whilst the Pre-Amplifier draws very little current we have used a colossal 1Kva mains transformer because the improvement was considerable.
Adding over 350,000uF capacitor power reservoir, half in the power supply, half in the Pre-Amplifier itself, also witnessed immense dividends.

AVID's obsession for perfection extends to all three building blocks, with a limitless desire that not one should fall short on performance.
The internal electronics commands the same attention to detail. The amplifier topology is a fully balanced design, in common with the Pulsare,
with exceptionally low noise and distortion across the audio spectrum, however, the Reference Pre-Amplifier uses an active RIAA stage rather than
the Pulsare's passive design, pushing performance to new levels of excellence.

As with the Pulsare, at no point is signal integrity compromised, using relays for every adjustment. Every input and output is optionally
XLR or RCA for complete flexibility and the phono stage allows up to four cartridges to be connected simultaneously for real vinyl aficionados.

Mono can also be selected, catering for the growing interest in this playback style. Added to this are three line stages and a fixed level tape output. Four main outputs allow up to four mono-amplifiers to be powered in either balanced or single-ended configuration.

AVID developed their own wound film capacitors with polypropylene dielectric, employing no less than thirty within the circuitry.
Being physically large capacitors they hang vertically below the main circuit board in close proximity to each other.
This can cause reduced cross-talk performance in this situation. Machined a 55mm solid aluminium block with individual pockets, then electroless nickel plated it to screen each capacitor.

Such an unrelenting obsession for nirvana bought AVID to the crowning glory and the "King" of volume controls.
They've explored and listened to more volume controlling devices over three years than you can begin to imagine. Digital resistor ladders, Burr-Brown chips, Bourns, Penney & Giles, studio-grade sliders and even bespoke rotary stepped attenuators with matched resistors from a man in a cave.
All were overshadowed by the performance the ALPS RK50 bestows and truly deserves the accolade "King" of volume controls.

Handmade from signal conductive plastic and manufactured to absurd limits, this key component is indicative of our absolute purist approach.
Gone is the conventional ‘performance-limiting’ remote control motor with its field effects and rewarded with a breathtaking perception of realism.

Why do others not use this magnificent jewel? The answer is simple...Cost.
Perfection comes at a price and it’s purely our self-indulgent and obsessive drive for perfection that makes AVID devoid of such thoughts.

Prejudice may stop you hearing, cost may prevent its purchase but to listen is to believe and believe us, this is "close to perfection".
