bobfa Posted January 10, 2018 Share Posted January 10, 2018 I have a temporary rack in my cabinet that I have setup to take all the gear in and out so I can change and test. Right now I have my Mytek DAC+ sitting on top of my JS-2. For spacing as the DAC+ gets rather warm I use hockey pucks. This is not for sound it is for air movement. Note that the DAC+ has a lot of air venting top and bottom so I assume it needs the air flow. The hockey pucks are too big in diameter and slide around. I am looking to add something between these two devices and maybe some others. There will be a MacMini in the rack this weekend and so forth. In the long run the equipment will be put in some sort of audio racking system and I will want some better vibration reduction and some “cool” factor. Any suggestions? This gear is physically small and a lot of the stuff I have seen is too big. —RJF My Audio Systems Link to comment

bobfa Posted January 11, 2018 Author Share Posted January 11, 2018 Oh I like those. I make 1in squares. And they are what 50c each or less....... Right in there with my hockey pucks but not slippery.... Thanks. I will look around for more things like these. My Audio Systems Link to comment

GUTB Posted January 11, 2018 Share Posted January 11, 2018 Mapleshade Isoblocks are more effective, give more clearance...but also more expensive. Note: Each one has two sandwiches stuck together -- there's four individual blocks in this picture. I use these for my own speakers: Link to comment

They are principally used for industrial equipment vibration isolation but work well for us. You could stack and glue them to get the same as Mapleshade. Search for "cork isolation footer". They are very cheap on eBay. You can get 12 for $11. I often use them along with some Mapleshade brass weights put on top of my DAC or preamp. I have real hockey pucks also but they are quite hard so I do not believe they are as good for absorbing vibration. "Don't Believe Everything You Think" System Link to comment

GUTB Posted January 11, 2018 Share Posted January 11, 2018 On the subject of Mapleshade, their CDs are among the best Redbook masterings available. Highly recommended. Link to comment
Milt99 Posted January 11, 2018 Share Posted January 11, 2018 Yup. Mostly used underneath house furnaces. But remember, MapleShade sprinkles their maple syrup majik goo and then cryos them to get the molecules in harmonic synch and that ain't cheap! Link to comment

Ryan Berry Posted January 12, 2018 Share Posted January 12, 2018 The main suggestion I'd make is to avoid anything fully rubber. We used to use rubber feet in the early years of Ayre and to this day get units back that have flattened over the years of continued heat and weight. I'm not sure what the hockey pucks would do over time, but you may have dinner plates in 5 or 6 years! President Ayre Acoustics, Inc. Link to comment

It is the "maple syrup majik goo and then cryos them to get the molecules in harmonic synch" that is the value added component that allows them to charge $24 insted of $8 for basically 8 glued up furnace footers. Actually these are the least suspect devices that they sell and they do seem to work. IMO. "Don't Believe Everything You Think" System Link to comment

I use these for my own speakers: Low bass reproduction can physically vibrate/move a speaker, compromising the clarity of the bass and midrange. Your speakers should have as little freedom to move as possible. Isoblocks are basically filters for low bass frequency feedback coming from the surface an object rests on... useful for electronics and players but not for speakers.... they actually increase the instability of the speaker. Your stand should be rigid, tightly coupled to the floor and allow the speaker to freely radiate sound in all directions. mourip 1 Regards, Dave Audio system Link to comment

GUTB Posted January 12, 2018 Share Posted January 12, 2018 Mapleshade claims they invented these things and warns against knock-offs. Maplesahde as a company is reputable. Their brass footers do work -- eliminated footfall noise from my turntable (although the spring feet it comes with are more effective overall in terms of sonics) and helped a 845 SET a lot. They claim that their air-dried maple shelves work better that kiln-dried butcher blocks -- I don't know because I could never bring myself to spend $200+ on a block of maple when you can buy large heavy maple butcher blocks for less than $100. Maple audio stands are quite attractive though. Mapleshade and Timbernation put out very nice-looking furniture. They just want too much for it though. Link to comment

We tend to avoid anything that compresses much, but maybe Dryflex CS could work if you liked the material. Our favorites are the wood blocks (of course) and Delrin, which is fairly hard and doesn't compress. Delrin's particularly nice as it mills real easy and can be used as a permanent foot without worrying about the material drying out and cracking or deforming. President Ayre Acoustics, Inc.
