Ingress Audio Engineering

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?

The V.2 plus a set of Geoff’s springs would make a great budget isolation system. @geoffkait, how do you recommend your springs be partnered with roller bearings? I may just use my Symposium Jr’s, double cup style, therefore not having to be concerned about the LFT’s rolling off the bearings!

My “budget” springs having been outperforming high priced isolation systems for more than 20 years, and have been used in some of the most outstanding systems at CES including Mapleshade, the big Tenor Rockport system and two John Curl Bob Crump systems. My springs have gotten less expensive over the years as I learned how to simplify and evolve the design. Anybody can over-engineer spring-based isolation system. It’s not rocket science. 🚀 My springs have isolated Verdier turntables, 200 lb Flagship Classe amps, $30K high power BSW Consulting tube amps, Lamm tube amps, great big VPI turntables, Raven turntables, and many other high end systems. By going to a smaller high-performance spring I could dispense with everything else - the two plates, the dampers -and use only the spring. Make sense? Wasn’t it Einstein who said a thing should be made as simple as possible?

Thinking on I still have two 16x16 x2 maple blocks from previous speaker endeavors.
I could fasten the Maggie's existing feet to them and roller blocks then under that.
Right now they would be direct into carpet.

Would maybe try two sets of the v2 first

I would imagine damping would be more appropriate as well as less expensive for dipoles since speaker isolation is primarily used to prevent mechanical feedback. And dipoles don’t transmit much energy directly to the floor. It would probably be much more cost effective to isolate the front end.

In looking at the diagram blowup of the GAIA on the IsoAcoustic website, I came to the conclusion that whatever isolation they are providing must be by way of some sort of rubber. They say it's not Sorbothane, but may it be Navcom? That stuff is still being made, and is used in firearms and other fields as mechanical dampers. I doubt it's the EAR rubber, but who knows?

I hope it's not, as the isolation properties of rubber doesn't extend very low in frequency, which is what we want. The lower the better. But remember when everyone ditched the springs in their VPI HW-19 tables for the SIMS Silencer Navcom pucks? Not all springs are created equal, and I don't think Geoff is going to share his secrets!

If I had the dough, I'd have a Herzan or Minus K under everything. Audiogoner folkfreak has his table on a Herzan (he had me over for a listen), and it's a thing of beauty!
