I wouldn't even think of changing components until you thoroughly experiment with acoustic room treatments. Be patient and give the system/room a chance to show what they can do.

Thanks guys. Ive posted some pics and ETF measurements on my web site. I think you can see what issues the room is bringing to the equation, especially in its untreated state.
Its pretty horrible - the decay time from a hand clap 'sounds' by ear to be around 1 second, maybe slightly less.
Also, the room isn't as wide as ideal to host the speakers, but Im hoping that by treating the first reflection points (walls and ceiling) with absorbtion I can make the room seem wider than it really is.
Luckily the leather sofa will be going as soon as I can find a suitable 'audiophile' replacement, and things like plants will be added during decoration. Do you know how crazy you sound when you start asking furniture makers about the type of stuffing they use in their sofas and if the know the sabine value of it! :-)
I was beginning to think the studios might be too large for the room, which they still might be. As an option I could 'downgrade' to Gems and use the extra cash to buy another subwoofer to help out with the low end.
Please have a look at the graphs and tell me where you think I should concentrate my room treatment efforts.
Would 1" foam at 1st reflection point and a PARC/TACt system for the low end 'solve' my problems...

thanks all for your invaluable opinions,
Ian: Your last line is a thread in itself now, isn't it? Problem with this hobby is sometimes we overdo it worrying about perfect sound and forget about kicking back and listening to the music.
That said, though, you seem to be unhappy with the sound, and your graphs do show a lot of peaks and valleys, indicating that you're not getting the sound you shelled out the big bucks to get. The PARC can smooth out the bass response up to about 300 Hz by eliminating the big peaks, and a TACT can do the whole frequency range, I think, but you should first be experimenting with different speaker locations (perhaps a little farther away from the walls, if you can do it) and room treatments (again, make them temporary until you see if they work) before shelling out money. Remember, as in the movie Pirates of the Caribbean, flat frequency response is really more a "guideline" than a hard and fast rule--in some cases a little extra bass and less upper midrange is more pleasing to the ear and more like what you might hear in real life, given today's prevalent recording practices. Experiment and use your ears as much as a frequency analyzer, if not more so. When it sounds right to you, that's all that matters, really. My two cents, anyway.
If you're going to use any foam you need at least 3" foam to do any significant good. You want real acoustic foam with an NRC rating. The 1 inch stuff only absorbes the highest frequencies and is little more than useless. Acoustic foam is a bargain compared to what we spend on the rest of our systems and can/will make a good to great improvement.
Vikingboy scary because of the large number of peaks and valleys shown room treatment isn't going too be something simple too correct it. the peaks require absorption the valleys require diffusion and the peaks and valleys are in narrow frequency brands which are harder to treat than wide frequency bands are. Exactly what is your "rubber" flooring?
