“I finally got round to fitting the Solid Surface sub-chassis, armboard and cross brace and can say, hand on heart, that these items make a significant contribution to a greatly improved sound emanating from my speakers!
The nice thing about the upgrades is the ease of fitting once the original parts are removed, none take longer than 30 mins and the sub-chassis allows for much easier set up of the suspension than the original. In terms of sound quality there are huge improvements, top end is clearer and more detailed and lower registers are much more defined and bass hits you in the chest! However mid-range is detailed and retains some of the ‘warmth’ that the LP12 is renowned for and something I like personally, female vocals in particular are excellent.
Set up: Helius Aureus arm and a Grado Signature 6.”
