Hmmm... given that 24/96 can't match a well set up cassette deck, I'm not sure if it could really represent the differences between turntables very well. People might be able to hear slight differences, and then regard them as precisely that - slight!
Actually, the differences between a modded SL1200 with RB250 and LP12 with RB250 are profound; someways the Linn wins, others the Technics. I don't think digital recording is quite up to capturing the scale of the differences, especially with most soundcards...
I'd just like to clarify matters by the way; I am *not* claiming great things for the stock SL1200. My point has always been that it's a cheap way into getting serious high end performance if you go the mod route. Spend £1,000 on it and you're into £5,000 Brit superdeck territory. Again, I'm not saying it's better in every way than any of these, but it is better in some, and worse in others. My point being that - in issues of bass grip and speed stability, it's ahead.
I am NOT and never have said it's better in stock form than super decks, but aspects of its engineering and build are just as good, if not better. Specifically, that alloy top plate, chassis, bearing housing and motor (and control circuitry) would not disgrace any deck at that price. If you don't believe me, pull one apart and decide for yourself!
I don't know why this is supposed to be controversial; I've had some prominent turntable manufacturers say it to me privately. It's just common sense. The point is of course that those buying a £5,000 LP12 Keel are not the sort to buy an SL1200 pull it apart and rebuild it by hand with superior bits where needed. It's not comparing like with like. Just because I could turn a £30k Suburu Imprezza Turbo into a Jaguar XK-R beater doesn't mean Jaguar sales will suffer; they're completely different markets. That's a no-brainer.
I've said in the mag that if you want a fantastic high end turntable, spend £10k and get an SME dealer bring it round and install it for you, then listen and enjoy. The existence of, or the tweaking potential of an SL1200, doesn't in any way challenge that. As I always say, different strokes for different folks...
