    Thanks for the tip Christian
    The upgrade took a while as I didn't expect the innovation could sound much better.It has made a big difference together with the Minus-K .Did you notice the magnetic platter thickness is different to the original Master?I changed the battery for my Acc+ Drive a few month back.As we bought about the same time have you had to do the same?

    One question for you, what did the Stillpoints bring to the turntable? Curious to know if it's a worthwhile expense considering the BM-8 is doing an excellent job job filtering noise.

    Hello Dan
    I'm a big believer when it comes to turntables, vibration is everything.I used the stillpoints for a number of years with the CL innovation and did the upgrade to master and minus-k together with a big difference .During my research I spoke with Mark Dohmann ( Dohmann Helix 1 Turntable) who explained minus-k and stillpoints work in different ways so both are beneficial to the end results.As its only been a week the changes are very apparent.But like most tweaks give it a few weeks and it becomes normal,

    I did not notice the difference in platter thickness....what's the story with that ?

    My original lead acid battery in the ACCU+ crapped out a few months back. I replaced it with a Powersonic lead acid battery and works great again. I'm glad it's user serviceable in that regard.

    I don't have details of the difference but if you look close to where the belt sits on mine there is about 5mm difference to the original .This must have been added to the half above to add the extra weight maybe......

    I'm a bit late to the party on this thread but hopefully not too late. Above is a photo of my Minus-k 150 BM-1 supporting a TD124 in heavy slate. The Minus-k does make a difference that can be heard. I wrote a review of this unit back in March 2013. Here's a link to that article:
    http://www.theanalogdept.com/minus_k.htm

    The review covers my initial setup and then impressions and observations.
    I hope this is of some use.

    Atm in comms w UK distribr of MK to audition BM-8 on an oversize rack for my rim drive tt
    Convinced about the potential performance from 0.5Hz isoln data and price wrt alternatives
    Less convinced about its fussiness re setup, and I need reassurance on how to get demo right

    I think the setup it not too fussiness for TT.
    What is your situation now? Can you send some photo of your setup ?Weight of your TT ,size of your TT.

    I'm going to make a commitment to an more robust isolation platform. Currently, I have a mass loaded table that was originally from a Goldmund Reference turntable with it's 2" thick brass plate on top. I've modified the footers to accept Finite-Elemente cerabase footers. .. it works well but I want to take it to another level. I am thinking of the Minus- K or the Spiers Robertson active table AM-DVIA-60x70

    Has anyone had any experience with the Minus - K going out of level over time? - this would be a critical no-go for me. Has anyone experienced the Spiers Robertson solution? If so, what is the cost?

    Thanks.
