Bottom Line:   
The Black Diamond Racing Mk4 cones are an accessory that I can't be without - they have worked wonders under every component that I have used them with. They provide a clarity and deep black background for the music when used under CD transports, DVD players, SACD players, etc. and significantly remove an "edgy" quality of CD playback, while at the same time letting more detail through. The difference with / without the cones is rather like listening to your car audio system at 60 mph, vs. parked with the music playing; a whole layer of "hash" is removed, and details stand out in contrast when the background noise is reduced. (The Mk 4 cones are more detailed than the more "tubelike" Mk 3 cones, but a mix of the two types is sometimes just right.)

The effects of the other Black Diamond Racing accessories are additive (and addictive!); the use of the BDR "Shelf" or heavier "Source" shelf (under source components) increases system performance considerably.

This is my 2nd review for mk3 and mk4. I made further improvements in my system. First I put granite under the audio rack which is Finite Element's Pagode, carrying all my equipments even my big power amp Audio Research VT-200 at bottom. Previously the rack was sitting on the carpet. This improved dynamics and soundstage significantly, but with metal spikes under the rack the sound was too bright. I put a combination of MK4 and MK3 cones under the rack over the granite, and the result was so satisfactory. Then I put a second block of granite under my power amp and a combination of MK4 and MK3 between them. A huge improvement again, details, dynamics, soundstage all improved. I changed cones under my cd player from MK4 to MK3 and also put BDR Source Shelf under my cd player and another set of cones (all MK3) under the shelf and pagode rack. Marvellous! Source Shelf is something every serious listener should consider. A big step over cones.
Finally I put granite and mk4 under my speakers which originally sitting on the carpet with ordinary metal spikes. It was such a significant experiment for me how distortion due speaker movement was degrading the sound.
Total result is a very dynamic and detailed system with a better soundstage without being too bright or over-analytical.
Black Diamond Source Shelf and cones gave me the sound that I have never realized or dreamed before with the same equipments I have. A very serious upgrade due to lowering distortion. Definetely recommended. Do not attemt to upgrade your equipment unless feel confident about distortion performance of your system!

Bottom Line:   
Adding BDR cones to a system in my experience is equal to upgrading equipment one level. But, it could be a greater increase depending on the installation. For me, it was greater than speaker cable, almost the same as going from an Adcom cd player to a Wadia.

In short, the highs were instantly snappier, the based gained texture, the voice quality was more real. Even when I expected some gain, the degree to which sound improved was more than I could have expected. It does help to support all of your equipment and speakers, and not just one piece. The installation calls for three cones per piece. Here in Dallas, Mr. Ron Meyer sells this stuff, and here's what he did in my system.

Ron snstalled it first under the CD Player (Wadia). Wow. Then under the Amp (Citation, and Adcom). Again, great. Then under the speaker, wow again. Then the pre-pro (Rotel) good again. Each add increased the sound quality in about equal amounts.

He then added the BDR round pits under the amp and cd player and the sound elevated again, in about equal amounts for each add. Next for me would be to add pits under the pre-pro and the speakers.

Note that I have a mfb 'rack'. Shevles are wood and fiberboard. The BDR cones really help with these shelves, I guess they don't work as well on glass.

Highly recommended.

Bottom Line:   
The $80.00 is for a set of 4 of these little black beauties (including the threaded posts). I had found that, while my 12" 120W Mirage Subwoofer had the necessary bottom end I craved in movies and music, it rolled off dramatically around 35Hz and the floor was shaking more than my teeth should have been.

I removed the threaded spikes from the sub and replaced with the BDR Cones, cued up Sheffield Lab's Track and Drum CD and was simply amazed - not only could I increase the volume on my receiver 15db higher than normal, I could feel every hit on the floor tom and bass with authority I never experienced before.

With some adjusting of the sub's crossover frequency (which I increased from around 55 to 75 - a much better match with my Mirage 190i's which bottom out at 45Hz) I replayed the same track with another 10db increase. This time I concentrated more on the vibrations in the floor vs the sound quality.

With both feet firmly placed on the floor I felt - nothing.

I headed into my basement, grasped the floor joist directly underneath the sub and felt - nothing.

Absolutly amazing! It was like getting a second 120W amp added to the sub and having it hover just inches off the floor! I was finally getting all the sound out of the box that I had originally paid for.

Next step, replace the spikes on my L/R speaker stands with the same cones because now the sub is much cleaner and faster than my mains!

This is a tweak that really works folks - get some and try it out under any component that produces a signal (even TV sets) you will be amazed at the difference they will make.

Bottom Line:   
I have used almost ALL BDR products except fot the T.Table clamp.

These represent the greatest bargain in High End Audio tweaks. They don't need any kind of break-in and will sound great right out of the box.

I put them under my CD player, DAC, preamp, T.Table but did not have much luck on my power amp.

Sense of space improved dramatically, midrange to kill for, bass firm with slam, soundstage with 3 dimentions.

Highly recommended! Great deal too!
