Isoacoustic puck mini's or orea bronze for 12 pound tube preamp

I had chance to put isoacoustic puck minis in and spend a small amount of time with them. I left DH Cones under CD player and placed pucks under Preamp, then later tried other set of pucks under phono pre. 3 pucks sound different than 4.  I'm going to try CD player last. First impression they don't show such a apparent change as DH Cones did on CD player. DH Cones keep the fullness and cleaned up the highs but did not seem like a tone control. The pucks seem more like a tone control. It does alter the highs but I need to spend more time to get use to what's going on. It is doing somethings right. It does have the rubber footer sound thing going on. It must have some type of spring in there. With index finger on top and thumb on center bottom it does not compress or move at all. Put you fingers on outer radius of bottom and it will decompress like a shock absorber. Soon as I have more time to listen I will report back lak.

Thanks for the post. I look forward to reading more of your impressions when you have more time to listen.

You mentioned there's a definite sonic difference between using 3 pucks vs. 4, but you don't say how or more importantly, which sounds better!?

@paulcreed ,Was wondering if you could share your "extended" experience with the mini pucks under the preamp. I was thinking of getting the Isopuck mini over Orea bronze under my preamp and disc player.

+1 update needed. What worked and where did you use them, number used etc.
