To say hi end racks don't work period and solid state electronics can't benefit at all from isolation or vibration reducing tweaks is insane. You probably never tried I'm going to try and remember these names so I can never take anything they say about audio on this forum seriously.
How important is an audio rack?
The difference in opinions is almost as heated as the great cable debate. Many claim solid hardwood is best. Others like no shelves but some even defend mdf shelves. One store owner/salesman stated the audio rack should be considered the most important component, even with a very modest system! My opinion is much more moderate, but i'm curious what others think.
