Not a Linn owner, but I think the fluted plinth gives the LP12 its classic look. AFAIK there is nothing else in the world of TTs like it. The proportions of the flutes are perfect to my eyes, working effectively with the height of the platter. The bevelled, black-painted bottom is an integral part of the design.
Linns flute design has never changed, suggesting to me that they know they got it right the first time. It is an elegant design that imv adds perceived value to the deck, & I'd have no other. I also prefer the original logo on the armboard. I love the look of
@SteveG's deck.
Solid, non-fluted plinths turn the LP12 into just another 1970s Thorens type deck, only boxier. The colour & grain of the wood makes no difference. I'll not wave away anyones preference for a solid plinth but, to me, *this* is a dated look.
