Hi Mark,

Am I missing something? This seems to be about power suppplies rather than platters.
Yes... The clue is in here (see bits in bold):

In short, the SR5-21 PSU, the sonic talents of which I already knew from hearing it at work in my own system, had made one of the biggest improvements to the SL-1210 I had heard so far in all my years of using it. But there was more still to come - MUCH MORE - and that would be realised when I analysed in isolation the sonic effect of the Mike New platter on my own T/T, which would make me realise, even when modified to this level, just how much more latent sonic potential the SL-1200/1210 still had to offer.......

I must get to bed now, as I'm up early for the Manchester hi-fi show tomorrow. Part 2 of my report will be continued upon my return.
It's a two-part review! And the bit about the platter is in part 2

However, the second part of the review won't be posted until tomorrow, as I'm just in from the Manchester hi-fi show and knackered after travelling miles going round in detours and sitting in queuing traffic, as they decided to shut part of the bloody M56!!

I have to say that I am entirely unconvinced by the supposed benefit of raising platter mass.
And, if you remember, so was I. However, it turns out that my scepticism in this instance was unwarranted

All will be revealed tomorrow!

Marco.
