It's interesting the question about butcher block, isolation, etc. I've read quite a few multi-page threads on the different forums about wall mounts, bamboo cutting boards, butcher block, sorbothane, plus many more ideas about whether Regas require additional isolation beyond the included Santoprene feet. It seems a cottage industry kinda thing that some believe the Rega machines require extensive additional siting or platforming to perform as intended.
One of the things I'm loving about this new Rega is that I've done absolutely nothing beyond leveling the non-adjustable Rega feet with little circles of black construction paper. There is no bamboo cutting board, no sorbothane, no heavy platform, no lightweight platform, I just placed it on the wood console that is the best place in the room for it.
IMO it has needed nothing by way of isolation or consideration of platform, beyond whatever is engineered into the turntable already. It is as quiet, as the stylus drops, as my Thorens machines. It is dynamic and musical and simple. I feel zero urge to change feet, or to add another platform underneath, or isolate with springs or elastomers, or anything.
I can certainly see wanting aftermarket feet for purposes of adjustability/leveling, but my little construction paper shims are cut so close to the feet themselves that I cannot see them from more than five feet away. Simple, functional, no muss, just beautiful music.
