It’s probably not that obvious but worth pointing out since inner tubes were just mentioned. The smoother and harder the surfaces are made for the roller bearing assemblies the more critical balance and level become, even if cups are used top and bottom, as I pointed out a couple posts down. Therefore, I humbly submit inner tubes are not (rpt not) a good choice for vertical isolation with roller bearings, or even used alone. Steel springs like you know who’s are a much better choice, not only because of the leakage issue but because inner tubes have a very non-ideal geometry for pneumatic isolation - the ideal geometry being tall and slender. I.e., large volume of air v per surface area in2. As I also just got through mentioning, there is some degree of vertical isolation with ONLY roller bearings and cups. Which reminds me, the reason some components can be mounted directly on bearings with no cups is probably because the hard roller bearings make slight depressions in the metal of the chassis base.

I recently discovered the benefits of isolation. Don't know how many of you are familiar with
Barry Diament's
recommendations for his hip joints. The recommendation for the economical DIY set up worked well for my stereo; (lightly inflated bike innertubes, wooden egg holders supporting stainless steel balls).

A month ago I bought Isoacoustic Oreo's. 3 per component (weight appropriate) and was very impressed...at first. After several days of settling my music sounded dull and lifeless. I reread the optimal weight recommendations, re-calibrated weight limits with temporary improvements. To my disappointment I realized the Oreo's could only be compressed (especially after the suction seal was formed between them and the component or platform the component sat on). Sure they rocked in all directions, but they didn't glide in all directions. Only horizontal isolation was taking place so I coupled the Oreo's with Barry's economic hip joints which has greatly improved the SQ. I'm loving it but I still feel there's room for improvement. Mainly because I own the Hfiman HE-6SE HP's and I run them through my power amp's speaker taps. So I want Barry's upgraded hip joints under my amp. I'm interested in Ingress Audio's vibration isolation rollerblocks.

I've looked up info about their level 2's and 3's but specifics on their differences aren't given. I know Barry says the blocks should be machined smooth to a certain degree. I left a message with Ingress, but I'm impatient and wondering if perhaps the level 2's aren't as smooth as the 3's. The smoother, the greater the improvements. My question is does anyone know the differences between their Level 2 and Level 3 rollerblocks?
