Does Anyone remember

I'm almost cringing as I write this, knowing that any mention of a tweek, and it's "effect" is met with doubt or even boredom. Still, even though there may only be a few readers who can, or may have already tried this, I must continue.
I have been using a Pioneer PD S95 transport for about 7 years (great piece, look it up). It features the best version of Pioneer's rigid clamping system that is known to many, but no longer produced. It was a good idea. Clamp the CD so that it wouldn't rattle while it was spinning. The CD is inserted upside-down on these players, and the label side rests on a rubber pad atop a machined aluminum platter.
Anyway, it's the only high end transport I have ever had, so I can't compare it to others, but I have been very satisfied with it, and combined with an Audio Note 1x dac, it has been far superior to previous players I had owned.
To the point. Before owning the stable platter transport, I had used a product (no longer available) called Reference Bands. I forget who made them, but they were basically a stretchable circular black band that you placed around the outside edge of a CD. They were easily removeable. To me, the "pulled together" the sound of the music, making it sound deeper, and more nuanced. After I bought the Pioneer, I threw them out, as I believed that they were redundant. Then, last week, I pulled out a CD that I hadn't played in years, and there was a band on it. Long story a bit longer, I found that on disc after disc, the band in combination with the stable platter sounded obviously different, and after further listening, obviously better.
If anyone out there remembers the bands for better or worse, or has tried what I have, I would be interested in your thoughts.
The whole thing sounds so counter intuitive, but this has been my experience. I am using it all of the time now for critical listening.

the rubberband is periphery weighting the CD thereby reducing the wobble during spinning. If the CD goes upside down in the Pioneer, the clamp cannot be too big in diameter otherwise it'll cover the inside edge which has all the imp info of the CD. So, even tho the CD is clamped it appears that the entire diamter of the CD is not clamped so there is a high probability that there's still significant wobble during spinning which the rubberband takes care of. Plus, the black/dark colour rubberband also does what the Stoplight pen does - absorb the laser reflections off the CD edge. With those reflections gone less spurious reflected into the laser read lens hence less power supply spiking & the clean supply results in lower jitter & cleaner sonics. If you had TEAC VRDS clamping system it might obviate the need for the rubberband.
But, yeah, I can see how the rubberband helps the situation....

Thanks Ghostrider, I will look into that.

I wonder if it's just the edge weighting or if something else is at play too. I was at a site recently where they listed a bunch of cheap tweaks for cd's one of which was to dull the reflective edge of the disc with very light grit sand paper. I can't say what the supposed mechanics or purpose of this was but they swore it yielded a very slight benefit sonically.

I use pioneer stable platter pd65 and pd59 with outboard dacs and fine them a cheap and high quality way to reduce jitter and cd player noise...I've never had a breakdown of any of these models. Quiet and smooth

I used a PD65 CD player for several years before the current PDS 95 transport and Audio Note DAC. It was truly an excellent player.
