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?

am aware of the challenges of inner tube in both setup and performance as you eluded to - has to be just right and thus my reference to trying wave springs etc..just not sure what and where to get them yet, ideas?  

Additionally, substitutes for marble that I currently use, especially for heavy monos (which I don’t for those and use a top and bottom cup with MDF due to their 90lb weight

Have considered the Townsend products (would love to try them) especially the platforms for speakers but like you stated are costly.  

I do use the GAIA’s on my spkrs and although not super inexpensive, they do perform very well.  Priorities really and one has to pick where to focus $$.  Currently looking to upgrade DAC sooo...

I do do keep an eye out for their products used, but rarely come up, at least for my application and or timing.

>>>>I design high carbon heat tempered, cryo’d compression springs for moderate loads 25 to 70 lb and Super Stiff Springs for heavy loads, 75-200 lb. Both types of springs are suitable for placing directly under a component. Performance circa 2-3 Hz.

@uberwaltz, Barry Diament wrote that the roller bearings made more difference under his Maggie 20.7’s than under his electronics. But then he uses all solid state stuff, and records in digital. He uses the 20.7’s as monitors! You can see them on his website. He bolted the stock Maggie feet onto a 2’ square piece of plywood, then put a trio of bearings under the plywood. What I wonder is if he puts the bearing cups right on his carpeted floor, or on top of something else.

I have my Eminent Technology LFT-8b’s bolted onto Sound Anchor stands, which are a tripod design (inherently more stable than four feet, as found on loudspeaker outriggers). The SA’s come with spikes, but a set of roller bearings, GAIA’s, or Townshend Audio Seismic Pods can easily be substituted, which is what I intend to do. The Pods would run about $600, the GAIA II’s (good up to 120 lbs.) also $600 (they come in packs of four, so I would have two left for some other application), the Ingress V.2 only $140 if used single-cup style. 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!
