Duet

With the Duet, the system produced quieter backgrounds and somewhat reduced layer of “haze” probably caused by high-frequency hash. It also didn’t limit dynamics

What the DUET does is exactly what it is supposed to. It lowers the noise floor without restricting dynamics

. . .with Duet, it had a definite increase in presence, it just seemed more there

The Clarus Duet power conditioners are one of the best performing I’ve heard at any price
