Thanks for your responses. When I first decided to upgrade the Benz I'd decided on a Dynavector 20X2, based on past experience of that manufacturer. Admittedly, in those days they were called 'Ultimo' and it was more years ago than I care to remember. Then I began to consider just how 'good' a cartridge the RB300 arm could cope with. In so doing, I walked into a minefield. Actually, given my absolute top whack of 1,200 pounds (and even that started to creep into the "well, maybe about" region it was more like walking into a top class fancy Paris boulangerie and being able to select just one of the many delightful looking confectioneries on display. Which one to choose, and would I like it when I tasted it, or might I wish I'd chosen that other one with all the cream on top?
I've spent a long time in the cake shop seeking out the opinions of others: "You'll love that one with the fancy icing," "Oh, I prefer that one with the nuts on top," "Surely, this one here with the chocolate filling is right up your street?"
Okay, so it wasn't fancy cakes, more DV-17D3, or, AT-AR9, or ZYX this, or Lyra that...(why are those men in white coats walking up my drive carrying a straitjacket?)
Then I get two eminently sensible 'vinylengineers' suggesting I stick with what I like and just upgrade to another Benz cartridge. Well, why not? The Ace SL is well within my budget and I do like the musicality of the Micro Gold. But, I could possibly stretch to the Glider - or even the Wood S, though one website rates the best loading for the Glider at between 1000 - 47000ohms which may not be well suited to my Linn Kairn MC input rated at 150ohms...so, it has to be the ACE or the Wood S...but, which?
Unless, of course, you can suggest an even tastier cake...?
