A nice PC upgrade

worse case, it gets the puter off the floor and less dust to blow out every other month

Thanks for sharing your experience.
Where did the PC use to sit before? From the quote above it could be on the floor and that would kill this hypothesis: could it be you have now taken a vibrating device off a shelf where you have other sensitive equipment? That PC must be vibrating a fair amount, with 3 HDD and a fan or two.

My PC was previously under the desk in the office, on an oak wood board with 8 symposium fat pads under it. Replaced the oak board and symposium with the mapleshade system. There is definitely something to it. Computers are definitely the noisest place in the world.

I believe improved sound has something to do with the wood vapors seeping into the hard drive and coating the internals. I hope it is a maple wood and not a sycamore platform. Eventually sycamore tweaks can cause hearing issues.

If you can get our head out of your butt, you are welcomed to come over and actually hear it yourself.

It's a custom gateway, intel quad core, 16 gigs ram. PCI sound card and three internal 10,000 rpm drives. 10 meter apogee spdif cable ifrom pc (in next room) and into esoteric G25u clock/upsampler and into esoteric k03sacdplayer for dac. Jrivrr19 and I'm pinching myself."

Does having a powerful computer like the one you list really offer better sound quality? I never thought playing music on a PC was very resource intensive. What about AMD processors? Do you think it would really sound different than an Intel?

Getting back to your original topic, have you ever considered upgrading your case? If the brass feet and wood blocks really make a noticeable difference, I don't see why a better case wouldn't be an upgrade as well. Have a look at Corsair's Obsidian series cases. Not only is it very well built, but its actually designed to be quiet. I have one myself, and if anything ever happened to it, I would definitely buy it again. Its not too expensive (150-175), and Tiger Direct usually has them in their stores. Everything's standardized, so whatever you have in your Gateway will fit in a new case.
