Interesting to hear nailed down descriptions of improvements - I've never really heard any brashness in my system. What these do for me is soundstage based and air round instruments - which i guess is soundtage! Detail - detail detail rather than type of sound is also a big thing and that is the clincher for me at any rate. I like detail and 3D images. Anyhow I feel i should apologise for starting the whole thing off but it's been interesting to see the argument (sorry discussion)  taken up so whole heartedly. I've some more experiments to do with this machine and shall report back due course but probably after this xmas thing.
