My amp uses 8 tubes and has no feedback so controlling the bass isn't hard.

The tubes I used when I had the rs-1's were much too bass heavy, and the bass actually intruded on the mids, it was not good. I'm quite happy with the tubes I use now that Zanth sold me. I do like a good dose of bass though, as long as it isn't bothering the rest of the frequencies.
My new cable is around the same bass heaviness as the old cable, but it has more fullness to it, and yet its tighter, clearer and faster. Before I couldn't hear the extended low-end people talked about, I just heard the lower octaves being played back louder then the rs-1 does. Now that the extra bloat in the bass has been cleared away, I can hear that they do indeed go lower then the rs-1's.
Whats really impressed me about the cable is the increased smoothness. Before the sound was liquiid, but it was missing that last bit of liquidness that the omega II's are known for. Close but no cigar. Half way between rs-1 and omega 2's I would say. Now with the upgrade, the omega may still be more liquid then this, but I don't care, because to me there is nothing to be desired anymore. ^^
The other thing I'm noteing is the soundstage. Recordings in my system had nice depth in my system before, but the placement on the singer was always the same, a little bit less forward then the rs-1's. Now depending on the track, the singer may be up in my face or far off in the distance, and everything is very focused.
The other things I'm noticing is that everything is oh so clear and free of distortions. Also the prat is even better then before. Cymbals just blaze. The tone is similar to the old cable. I have to say this cable has been quite the pleasent suprise.
Biggie.
