Any racks that use coasters/ wheels ?

so the fact that it's on coaster wheels doesn't impair sound quality. Mobility is extremely important for this heavy equipment.
 

Common sense tells me that rubber wheels are important to avoid vibrations reaching the floor and vice versa.  
 

I think all this isolation crazed people need to focus on common sense approaches.  Spending thousands and thousands on these crazy racks it's kind of bizarre
 

I think the vibration rationale for improved sound when using coasters is laughable The only people saying they hear a difference are those marketing the product.

Yes you need to isolate a turntable obviously. components come with special feet that offer isolation as they should.

And amplifiers certainly don't need isolation as they are built like a tank and quite heavy. 
 

Maybe if you live on top of the subway platform or a raging Street prone with lots of noise but then why bother if this happens.

Clearly racks are not designed for usability by most people. Once you put them someplace they pretty much have to stay there. Mobility is lost.

Why don't rack manufacturers do a better job here.
 

I wanna stack two Mono blocks but there is no rack that is sold with coasters. The rack is too small, etc. A wonderful market opportunity that no one takes an interest in.
