Thanks for the advice. Few bits more info in case it's of value.
Speaker cable is Chord Odyssey. I have some pure silver interconnects.
I get the cart recommendation, I'm interested in looking at a high range for that. What sort of price / which cart, would be sensible to upgrade to? Thanks for the advice on the Lyra, will look into this.
With regards to isolation I have some in place, decent enough rack and some Sorbethene feet on most of the kit. I'm not convinced with the value of expensive isolation pieces I've tried quite a few and can't tell much difference. I'm on a concrete floor with the speakers so may have something to do with it.
Never heard the difference between mains cables, I'm still not a believer having heard £3000 worth of them and couldn't tell the difference. I've had Ben Duncan mains conditioners which seemed to work well.
Interesting on the phono stage, I see the Linn is very well reviewed across the board, surprised it's coming up as a weak component. Not sure how easy Herron is to get in the UK, I wouldn't buy new there are simply too many bargains second hand floating around. I find the balance of the system to be fine so wouldn't want any more valves (not that the Herron has them), which could bloat the sound.
Ultimately I like a big soundstage and although good I think it could be improved.
Thanks, Tim
