AV Roomservice EVPs under the REL sub...
Ordered a set of EVPs from Norm Varney's AV Roomservice on Cyber Monday and put them under my REL sub tonight.
Wow...

Re: AV Roomservice EVPs under the REL sub...
Man, I cannot believe the improvement putting the EVPs under the REL sub made.
They made the room notably quieter. This translates to notable improvement in transparency, detail, pitch and timbre accuracy, and resolution in the bass, mid-bass, lower mids, mids, and upper mids through the entire presentation.
This cartoon from Norm Varney at A/V Roomservice depicts what they do quite well.

I've got two sets one under the DAC and one under the preamp and they do work well. I am only using the tripod method with mine though instead of four. Probably work just as well under speakers on wood, tile or suspended floor similar to Orea's just wouldn't be any attachment.Main - JVC QL-Y7/Denon DL-301 Mk II, Gold Note PH-10, Jays CDT3 Mk3 , Auralic Aries G2.2, Holo May KTE, Supratek Cabernet, Kinki Studio EX-B7 monoblocks, Verity Audio Otello, (2) Rythmik F12SE, Audio Envy IC, SC & PC's, Triode Wire Lab PC's, Inakustik USB and I2S, (2) Puritan Audio Labs PSM-156 with Groundmaster City, Timbernation rack

Re: AV Roomservice EVPs under the REL sub...
Start here...there is lots of information to review. Also watch the videos.
EVP Equipment Vibration Protectors | A/V RoomService, Ltd.
Norm is is one of the leading acoustical engineers in the United States, so everything is backed up by testing and data.
Also watch the videos...
Joe, Norm says if you are going to start some place, start by putting them under a sub.
Then, if possible, under speakers.
They also work well under components and specifically under components that are particularly susceptible to vibration. So, a good place to start under a component would be DAC because the crystal oscillators in DACs are particularly sensitive to vibration. The EVPs brought a notable improvement to my Gungnir MB DAC when I put them under it.

Re: AV Roomservice EVPs under the REL sub...
What type of floor does your sub sit on?

Re: AV Roomservice EVPs under the REL sub...
I have been meaning to try it for a while now and didn't even know there was a Cyber Monday deal....
Stephen, what made you decide using it under the RELs first vs in other places, like the components or even the speakers ?

Re: AV Roomservice EVPs under the REL sub...
Hi Paul,
I'm still studying and learning about this area, but my understanding is that different components, depending on their function or construction, need different things. With respect to speakers and subs, isolation is key, so that the energy from the drivers pressurizes (i.e., vibrates) the air, but not the floors or walls. EVPs under subs and speakers makes the room quiet.
With respect to components, depending on their construction, and with respect to mechanical damping, they mayt need different things. Components will little or no mechanical damping can be quite susceptible to vibration, e.g. my SOtM network bridge, which benefits from effective mechanical grounding (e.g. Stillpoints) to a dense platform (e.g. rock maple, slate, granite, etc.) to effectively transfer the vibration energy away from that component. Components with crystal oscillators are particularly susceptible to vibrational (as well as thermal) energy, for example. My Schiit Gungnir DAC, which also has crystal oscillators, also works well with Stillpoints under it.
Other components that are well-damped with respect to the impact of vibration, would generally benefit from isolation.
So, presently my working hypothesis is that Stillpoints are good for mechanical grounding; EVPs are good for isolation.
Subs need isolation.

Re: AV Roomservice EVPs under the REL sub...
The Black Friday and Cyber Monday deals were only promoted on AV Roomservice's Facebook page. Not on the website.
With respect to the REL, that was Norm Varney's recommendation of where to start first; and I trust what Norm says. Norm's "the man" when it comes to acoustics and acoustical engineering.

Re: AV Roomservice EVPs under the REL sub...
I have the EVPs under my Lumin X1 and SMG i5 CDR. My experiences are that even very small changes in position of these can alter presentation.
