Wood Plinths: removable armboard or no armboard?

[mikmas]

Apologies, if ‘ridiculous’ and ‘tosh’ was not in order.

Thanks - but not too bothered really; it's only a turntable

They hold no appeal whatsoever, despite their high(ish) mass. Proper layered cherry wood construction is the way to go IMO.

Is that your view for all turntables Tom or just the TD124? I am researching this subject as I have just bought a 401 with a two layer plinth, looks like granite but is in fact MDF with a textured paint finish; I like the look & was considering making a similar one out of granite, Corian or slate, mainly because I have read that large deep wood plinths act as a sound board for vibration, which has made me look at which method is best for sound quality.

There’s a fantastic 30 page thread on slate and other plinth materials on Lenco
Heaven https://www.lencoheaven.net/forum/in...p?topic=1471.0

Lots of physics and materials info in there and a bit of acoustics. No real consensus though. (It’s a forum after all!)

Not entirely sure there’s a single approach to be declared overall winner - a Td124, standard Lenco, PTP Lenco, Garrard, SP10 all have different characteristics in certain ways

Anyway I know I’m not that keen on slate. Wood is good, my plinth is cherry with sapele surround, and (lately) arm boards that are similar to corian. In my view, for a TD124 and probably also for 301/401, the best approach is high mass solid wood. But other approaches - lightweight, skeletal, metal, even concrete (!) are certainly viable and have their advocates.

Nothing like a bit of post-purchase justification ... I’m sure none of us have ever been guilty of that ...

Thanks guys, & sorry to the OP for the slight thread derail.
