Black Diamond Cones ADVICE

I use the BD cones under my CD player and I found a significant improvement by using them with ART Q dampers as a foot to the cones. The Q dampers have a center dent that the point of the BD cones fits into perfectly.

Im planning on using them under my Rogue 99 Are the good for tube preamps? also where can I find these ART q Dampers?

David, most of what is posted has covered my comments as well. I have a bunch of Black Diamond feet but no longer use them. I had two Black Diamond platforms, and sold them. The comments about Walker cones, I agree with, under some equipment, but not all equipment. You are going to have to experiment to find what works. I suggest also trying the Mod Squad Soft Shoes, they are under a lot of my equipment, and work wonders in many enviornments. A lot of what works in feet is directly related to the power cords, interconnect cables, room acoustics and where the particular piece of equipment is located in the room.

In my living room a.k.a. my "Home Theater" I have a Sony DVD S7700 on a tall and sturdy steel and glass (1") audio rack with the other components below on different shelves. Do you think that these devices would have any effect on the audio or video quality? If so can are the Valid Points the best choice and how much do they cost?

BM, They will have an effect on the sound of the Sony DVD unit, you will notice better bass and a much better sound stage with the Valid Points than the BDR. Albert is right about not using them under every thing, I use them on my transport, pre-amp, amp, but not my dac,it didn`t seem to make much difference there,and I`ll try them with my turntable when I get one to see if that works. My pre-amp and amp are tubes ,so it made a BIG difference there, you can call Tom at 440-526-1724, he`ll give the run down on them, you have 30 days to listen to them, if you don`t like them you can return them.They do WORK WELL, you can read about them in absolute sound, they like them ,and so did M.F. at Stereophile, he like them very much!!!Greg
