The LM-845 Premium is a SET integrated amp that uses massive output transformers and a massive separate power supply. The driver tubes are 300B and output tubes are 845. I've upgraded the tubes to Western Electric. The authority, richness and soundstage this amp provides is outstanding. With the Aerial 20T V2 speakers it presents a huge soundstage that is silky smooth and powerful.
The Black Box is a Low Frequency Resonator Array that works in conjunction with the Atmospheres and FEQ X4 to solve bass node issues.
Based on inquires I've received I just want to make one thing clear: I am NOT claiming what I've put together is the same as making an E-mat. The maker of the E-mat says the magnetic mat has nothing to do with what's going with his product and says the magnet is merely there for convenience to attaching to components. Also, he states his is totally proprietary and came from his own research and development.
What I'm discussing here is the exact opposite of the E-mat. Everything used is not proprietary and is available in the public domain (E-bay), it appears the magnetic field being created is very important to improving the sound and using the graphene oxide is based on research that is all over the internet. The fact the magnetic field builds overtime if its not disturb (the magnetic loop is not broken) and more mats create a stronger magnetic field resulting in better sound quality seems to validate what is going on with what I have proposed.
So, bottom line, I'm just messing around as a DIYer. I'm going to stop talking about the E-mat on this blog (I've already dropped-off the thread). Please don't ask me anymore questions about it either publicly or privately. Thanks.
After looking at my order again its actually called magnetic sheeting. I ended-up calling them directly and asked them to cut the sheet into 8x11 mats which they agreed to do. When I got the order it wasn't cut but they gave pretty much an entire roll of the stuff which I believe was 30'. Anyway, this is what I used.
Hi Tom - thanks for the feedback. Good to read I'm not crazy thinking these magnetic mats help the sound quality. I've always thought keeping magnetic fields away from our stereos was the way to go. Maybe its actually keeping "stray" magnetic fields away but focused strong magnetic fields are beneficial.
As to the graphene oxide, I simply used a paint brush to apply it to the mats. I put the mats together while they were still damp. I didn't wait for it to fully dry. I continue to read about graphene oxide and I'm not totally sure its positive effects are all about conductivity. It seems to create a coating that can be used for many purposes including improving batteries, optics and electronics. I'm not going to try to explain why (because I don't understand it). Do a simple Google search. Its fascinating reading.
Thanks Bill. Here is what I've been using:
You can buy different quantities from this seller. It says for "R&D only", "keep out of the reach of children", etc on the label. So, I wouldn't drink it :-)
Also, please let me say I have no idea if this will work in every system. Its just a relatively low cost (ongoing) experiment.
