Once upon a time I used pointy metal feet galore, but for the past few years the only place I've had pointy metal feet is under my turntable. Whether or not I'm taking a sound quality hit with the current regime I just don't know. I just don't care very much, either, as my stereo has never sounded so good since I had a special room built for it.
Any racks that use coasters/ wheels ?
I know salamander does racks with coasters but are there any others?
Never understood why people don't like coasters for the racks. It's impossible to move a rack after being populated with components without major effort. Not sure the isolation value is all that meaningful, ie. Not using coasters. Unless you got a turntable
