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.
