Well, there is the ’cool’ factor of a vintage butcher block counter. And enjoyment of recycling.

I had 2 fairly long hard maple counters maybe 8" thick I brought from Brooklyn in 1970. Carried them place to place, never used them, sold at a garage sale for next to nothing.

Do you know a local woodworker who can plane it both sides to a new flat and parallel surface? Edges: some have concealed dowels, some visible dowels, (exposed originally or exposed by cutting the width (take woodworker’s advice) also ’cool’ looking.

A really thick one, overkill, could be cut to two (or 3) less thick slabs by a shop, used/joined various ways.

I have a counter in my office, made from Hard Maple: Sandwich Boards, 2" thick, only 10" wide, so I had my woodworker join them edge to edge, thus 6’ x 20" x 1-3/4 thick (after the plane removed the knife cuts).  They were from the JP Stevens Cafeteria which I designed when I was a youngster, salvaged when they merged with West Point Pepperell, a bit of nostalgia involved.

Would a real butcher block be going to far?

@bgpoppab Its not going far enough. If its solid wood, it will resonate, although due to the density it will take a bit more energy. It would work better if bonded to a dissimilar material such as plate steel. The steel has a resonance too, but bonded together the two rob energy from each other. This will make for a quieter platform into which vibrational energy from your equipment can be sunk more effectively without the wood adding energy of its own.

The benefit of end grain is that it’s easier on the knives, so they hold an edge longer.   An end grain cutting board is harder to make so costs more.  As mentioned, there’s really not much sonic benefit that justifies the extra cost.

I think another benefit of the end gra8n was it absorbed flids, acting to dessecate the surface  and therefore reduce bacterial growth.

But none of that matters for audio, except if you hear the ghosts of all the animals previously butchered on it.

butcher block is not going too far. its been a big thing for a coupla years for TT isolation. use it with some kinda adjustible feet to decouple or to offer absorptoin/suspension of some type
