Tube amp on the floor or on the rack?

If you put it on the floor you must get it up in the air. I had mono tube amps and the best thing I did was have a carpenter friend build me boxes filled with sand. Plus I then used Black Diamond cones to isolate the amps. Tubes need a stable platform.

I have my Audio Aero Captiole on the floor on an amp stand.Besides the fact it weighs almost 100 pounds,the air circulation is much better than if it were to sit in a rack. With it sitting in the open is dissapates heat much better.The down side,is it becomes more prone to dust.Time to buy an ionizer.

can your rack accomodate the vk-60 (~17"x24")? i've yet to find a non-custom "rack" large enough, although i have seen dedicated amp stands that worked well. also, the amp is pretty heavy for a top shelf. why are you opposed to having it on the floor?

another option: i have my vk-75 on the floor resting on BDR cones and pucks...allows adequate ventilation underneath and isolates the amp from vibrations.
