Isoacoustic puck mini's or orea bronze for 12 pound tube preamp

Any insight would be appreciated. I have a Bruce Moore Preamp that I use in a second system that is wider than deep. The  dollar savings going with the puck mini's is appealing plus I get 8 footers for $100 vs $150 for 3 orea bronze, I could put remaining feet under phono pre. Using 3 bronze rated at 8.5 puts me at 25 pounds. Mini's are rated at 6 pounds which puts me at 18 pounds. I've read mini's are for speakers but have also read people put mini's under components. Has anyone done this? I'm sure orea sound better but how much better? Would mini's  sound better than BDR or DH Cones I'm using now, thanks for any advise.
