Stacking OK????

My rack offers similar challenges. I made an isolation platform that goes between my dac and transport. Double thickness of mdf with a layer of thin rubber between the two layers (roofing membrane.) The two layers of mdf are screwed together to compress the membrane. Then I glued a sheet of 16 gauge copper plate to the underside of the platform for rfi/electromagnetic shielding. This is supported with 4 of the Parts Connection's small rubber feet. You can bullnose route the edges or install a wooden molding to make it look presentable. I then support the dac with Black Diamond Racing cones on top of the platform. Works great for not many $$.

Photon; that's an impressive solution-- one that only a good audiophile would come up with-- kudos. I was just going to suggest Harnelt try the stacking and see if he still likes the music/sound quality. I think that ideally you would not want to stack components. Cheers. Craig.

One thing I would recommend is to put some type of buffer between the two so you dont put scratches on the top of the bottom unit.

I second perfectimage's important comment Even if it is something flat you still want to have something made of soft paper (coasters!) or felt. Rubber feet will eventually leave a residue, and even flat plastic will leave a mark from being shifted around.
