Salamander Synergy Rack Experiences?


I am considering purchasing the Salamander Synergy Rack for my large audio system. These are among the best looking racks out there and have vented doors available to keep 1yr olds fingers out. However, even though they are great looking, I have some reservations as to the "Audio Qualities" of the rack. They use MDF supported by Aluminum Extrusion. My first guess would be that this sux for audio, but I'm looking to the group for their experiences. I'm also considering putting some nice matching doors on some of the dead quiet Zoethecus stands, but that would cost about 3-4X as much.

You can fill the aluminum supports if you want, but that should only be done if your shelves won't need moving soon. My Synergy rack works fine with the chrome feet. One of the shelves comes with a base for extra support. I put my amp on it. I bought another one for my cd player. No problems. I switched from a fairly expensive ($750) rack which was more style than substance and now have an improved soundstage with pinpoint imaging. The Synergy rack did help some, but good cable choices made all the real difference. Sure looks good next to my B & W 805's though (matching cherry wood). Has anyone tried filling the supports with shot or sand yet?
I own the Salamander rack for a secondary system and the Zoethecus in my main system. I'm happy with my Salamander rack and would recommend it. It is on chrome feet but I do use both isolation and absorbtion tweaks on the CD transport and Jolida. I'm sure if you spent a ton of time you could get just the right synergy between your specific rig and a particular rack but I don't know if it would be worth it.
I find my Salamander Synergy double extension rack to be exceptional well designed and engineered. It is sturdy, stable and nothing moves. The shelves are very strong and do not flex or vibrate at all. There is a a wide assortment of accessoriesto enhance the cosmetic appearance to suit most any interior needs.The price is reasonable for the high quality and extended longevity delivered by Salamander.
