Hi Arthur,

Ah. You do like your cans of worms. Well, Marco, from what you have said regarding the importance of the various offerings, it is important to us that what we have is as universal as possible to the majority of readers.

So for simplicity (and consistency) we most often use a standard Techy. Little point talking about something that the vast majority of people do not have (at this stage) and so cannot relate to.
I like cans of worms? Lol - no, not really. I just like to get everything out into the open, and discussed, which is relevant to all those interested in the subject. We don't hide behind shrouds of mystery here, like some others I could mention

So all your testing with the acrylic platter has been carried out with a stock Techy? Interesting......... I presumed that because you were working with 'wonder-boy' from Dartmouth, you'd have used a Timestep bearing and PSU.

Regarding the bit I've highlighted in bold, that's fair enough, but why should those you refer to consider upgrading the platter before, say, the PSU? Novices are unlikely to grasp the importance of a platter upgrade, especially when it's going to cost £600.

And for others, upgrading the platter first would be a rather odd course of action, would it not, considering that the stock PSU is one of the biggest limiting factors of an unmodified SL-1200, and can be upgraded for much less than £600?

I could bring the old horse > bolt > door analogy into the equation again, but I won't.....

In my experience, those who are interested in modifying the Techy to a serious level (beyond attending to relatively superficial items, such as the mat and support feet) tend to go for a PSU or tonearm upgrade first, long before they will consider doing anything with the platter....

Therefore I presume that you've looked at the bigger picture, and so have plans at some point to introduce your own PSU (and perhaps bearing) which compliment the sonic characteristics of your acrylic platter?

Knowing you quite well, and how thorough and how much of a perfectionist you are, I'm certain that will be the case. As I'm sure you'll agree, it's critical that such modifications are carried out holistically, as a system.

In fact, in that respect, whilst I'm obviously keen to hear what the acrylic platter sounds like on my own T/T, I'm beginning to wonder just how relevant my findings will be, based on the fact that my T/T has been judiciously modified with a specific sonic goal in mind, and as such contains products complimentary to achieving that goal, which may not harmonise with 'alien' items introduced into the chain, intended to have a different effect.

But let's do it anyway, as I'm sure it'll be fun and most certainly informative!

Marco.
