I've also compared the two together, side by side not days apart and stand by my opinion, which is totally irrelevant now in any case. Time will tell. Lost the argument? Well, I thought it was a robust discussion of two speakers costing well over two grand the pair (the Tannoys now retail at £3500) and in the same way the OP is now changing amps at a rate of knots to get the speakers to perform the way he wants, the SHL5's were used with an amp that I think was the wrong way round (should have been an R preamp with standard 7 power for example, since the R version of the pre brings subtlety and finesse that is diluted in the otherwise excellent stock model).
Yep, I know shouldn't give a toss what other people do and, as Jerry will confirm, I have difficulty with serial box-shifters too

Each to their own and I'm trying to understand it. I've just had too many experiences with myself in the past, blaming what turns out to be the least problematic part of a hifi and changing it, causing ever more problens subsequently. It's a bit like a reformed smoker evangelising about not smoking, if you see what I mean.
All this is after the event. The OP has made his choice and must live with the consequences. No doubt the source, cable and amp journey now embarked on will prove great fun, if costly
That's it. I'm done.
