I got the quantum clarifiers from a 20% off sale at Parts Connexion, figured I couldn't pass up the chance to try some Bybee stuff at this price. I have a simple 15" single driver open baffle speaker with a super tweeter. So slapping on two Clarifiers on the driver magnets treats the whole frequency spectrum - so easy!
The difference is not huge, but I can clearly hear the improvement. I've had them on for about 5 days now. I've been hearing improvements every day. Since the improvements have been building day after day, its hard to quantify how much total. So I think it would be a hard thing to review properly.
They do clarify! Individual instruments have more space around them and stand out from others better. For instance I am listening to a high rez Chet Baker album I discovered recently on Qobuz (
HERE). Beautiful sound, very vivid recording of trumpet and sax. The trumpet and sax stand out further in the mix with increased dimensionality, focus. Without adding to any etched quality. Overall increases in organicness, more saturated tonal colors, sounding a bit rounder in a natural way - sax sounds more like sax, trumpet, more like trumpet.
Highly recommended for anyone that digs increasing tonal colors, organicness, and flow in their system.
