Purity Extreme debuts at RMAF 2008


 

 

The Purity Extreme linestage incorporates a full dual mono design with balanced inputs and outputs. Bass is deep, tight, fast and authoritative. A clean, crisp yet lively midrange and upper end with an uncanny sense of air and detail brings emotion and realism back to your listening experience. The use of quality components throughout allows for a great sense of detail, transparency and resolution while maintaining the musical purity true music lovers lust for.

The goal with the design of the Purity is an obsession to be as true to natural live sound as possible. Not neutral as in tube sound vs. solid state but natural as it's heard directly from instruments both tonally and dynamically while still being able to preserve the true sense of space for both instruments and vocals.

This is accomplished by using Baltic Birch Plywood for the sub chassis. After several years of 'listening' to different mediums, we have found Baltic Birch allows the Purity to produce a presentation that is like live music rather than a synthetic hi-fi sound.

The Purity's noise floor is exceedingly low -- below audibility in fact which helps it uncover the highest level of detail in a way that's unmatched. Coupled with this is a very forceful, immediate presentation that, along with that non-existent noise floor, makes for exceedingly wide dynamic range. There is also a forcefulness, especially in the bass, which has great depth, power and speed, that will have you pulling out some of your favorite recordings just to hear what emotions the artist was truly trying to portray.

The Purity uses a pure, clean effective zero feedback circuit based on the 12AU7 dual triode tube (one per channel) allowing tube rollers an affordable solution to roll tubes as your hearts desire.

Everything throughout the Purity is 100% hard wired with a combination of silver over copper wire with a Teflon dialectic.  There is not a circuit trace to be found anywhere. A dual chamber sub chassis eliminates interference between the power supply and analog circuitry.
