I've considered looking into the racks available from www.timbernation.com . Might be what you are looking for as they look solid and stable.
Stable component rack
I am looking for opinions on Salamander Archetype 5 component rack. I would appreciate if anyone can share their thoughts based on their own experience with this rack. How stable is this rack, how does it affect the overall sound of your system, etc... The reason why I am considering the Archetype is that the price is good $249 and the possibility to change the height between the shelves to accomodate different size components. I don't own a TT, so the rack would have to just accomodate for trasport and dac as far as the source is concerned. Any advise is appreciated. Oh...and I don't want to build it myself. No time to drive around looking for necessary parts. I'd rather just buy the Salamander and assamble it. Thanks.
