Thanks guy's , guess I will just have to take the punt.
Mario , what I don't want to do is go backwards in terms of musicality , in this case I mean PRAT or foot tapability
I don't want the tonal balance to change or loose any timbral resolution,
So I know what I don't want to happen but in terms of improvement , well to be honest, I am not really sure as it sounds great on good recordings to my ears.
My problem is that all my references are getting pretty long in the tooth and without wishing to put anyones nose out of joint I haven't heard anything locally that I prefer.
I do wish I could get down to your place for a listen or over to Tuyens but at the mo things are a bit unstable health wise.
