The Bybee stuff is the real deal. Things improved everytime I added a Bybee piece, especially his new 'Golden Goddess' line. As simply as I can put it, the Bybee stuff improves musicality (without softening transients), and gives the music a natural richness. Everything just sounds more real...less hi-fi. As an example, you'll hear the obvious difference between a nylon string or a steel string on a guitar, voices especially sound more real, even things like recorded hand claps now sound fleshy. The effect is cumulative, as I found the more Bybee I added, the better everything got, and I do mean everything. (I don't think Bybee makes his a/c Quantum Charges, but if you find one used, get it. You plug it into the IEC inputs of amplifiers, preamps, digital, etc, and then plug your power cable into it. They originally retailed at $475.)
You will love the Venustas, no doubt.
Best of luck, let me know how everything works out for you.
