Actually the PD-441 is not so heavy, i use two PD-444 turntables with stock feet, why you don’t like them? I think the stock feet designed with the same idea that used in Audio-Technica AT-636 pneumatic suspension insulator (those are very good). Last week i almost finished my own design of turntable rack for Luxman PD-444, it’s not completely finished yet, we’re going step by step. I was inspired by the studio racks for the untimate vintage broadcast machines.
@bdunne last year another experienced a’gonner (213cobra) and a proud PD444 owner adviced me the following:
I’ve never done so, because i don’t like how it looks. I like The Stillpoints, but they are way out of my budget for feet, so i’m fine with Luxman stock feet. Maybe i should try my AT-636 pneumatic insulators, but i think aesthetically it's bad idea for PD444 (which is the best design among the vintage turntables, imo)
