Congested sound - more power or resolution?


My sound has improved markedly with the upgrades I have done. One part of my music collection still isn't right though. Previously at higher SPLs all music got bad slap echo and bright, room treatment has sorted that out.

Now with some tracks mainly rock with guitars especially, the sound gets congested, image is lost and it gets grungy. Have I met the limits of my room, or with more power would I have better control of my speakers under a lot of stress? Or would a better quality spinner give more improvement through better resolution in the first place?

My system in in my signature, but breifly Arcam DV27, Meridian 861, Krell Showcase amp, Wilson Sophia.

Both player and power amps will get upgraded, I'm just trying to prioritise my budget.

IIRC - I seem to remember reading that power conditioning was not necessarily the best thing. Note that many of the top end systems here on audiogon do not use them. Would a similar effect be gained by using more specialist power cables?
Onhwy61 - I'll revisit some tracks and post.

Matrix - I have tried moving the speakers around a lot as per WASP, but it only seems to happen on tracks with say >6 instruments at high SPLs. I'll try again when the Wilson's are repaired.

Stehno - thanks for your comprehensive reply! My experience with power conditioners is "zip" - I'd love to audition some units - which would you recommend? And can they provide units capable of UK voltage / frequency?

DGarrettson - certainly the Meridian 800 is on my shopping list - obviously well matched with my 861 - I'm thinking of holding off until they decide which way to jump on bluray/hdef-dvd, but an older model should easily upgrade.

Thank you all for your advice.
