Find an amp stand that has replaceable threaded spiked footers and replace them casters.

Few months ago, I purchased a pair of Pass 160.8s. (141.0 lbs each) For last 10yrs, I have used BDR, "The Shelf" spiked to the floor for my Spectral DMA 360s about 65lbs each.
I bought a pair of Mapleshade record rack casters, believe they are rated for 360lbs. The Pass 160.8s +(2) BDR  Shelves = 210-220 lbs each. The Pass 160s are Large; took (2) Shelves for each amp. Moving the amps is no problem. Very solid,large casters, Well made. I think they were $120 each. Best Wishes on your Journey.

Sound Anchor can do exactly what you want.

I highly recommend Sound Anchors. Bob made a stand for me with wheels when I had a Levinson 333 amp, a beast. It glided easily across my wood floor and improved bass performance as well. The casters were high quality and worked smoothly.

I now have a pair of stands he made for my VTL double deck amps, even heavier than the ML 333. I chose spikes this time. With the spikes sitting on Sound Anchors Conecoasters, I am able to slide the amps on the wood floor without damaging the wood and have better coupling to the floor. If your floor is tile, this may be a problem because of the joints between the tiles and you should probably stick with wheels. Obviously, carpet would also suggest wheels.

Ive got carpet.  Just heard from Paul at Adona.  I may get a pair of his GX1 amp stands as theyll match my other Adona racks.  He has both casters and spikes that i can use. Ill probably buy both options.  This allow me to use casters to get amps into perfect position.  Once finalized switch to spikes or just leave well enough alone.

I use Herbie's Audiolab "coasters" with my spiked stands.  They are high quality and slide very well on carpet.  They also decouple well and make everything sound a little better.  You might try them with the spikes in whichever amp stands you decide to use.
