Given all the support, advice and comment that my cry for help excited, it feels polite to offer a view of where I've got to. Firstly, thanks to everyone who commented. There's a lot of practical information that has helped me get established and there'äs a lot more which has got me thinking or interested in investigating further.

Currently, I've moved the Stadium inside the right main speaker and close to the centre channel and TV. I can't report a big difference in the positional move - it was outside the right main - but it does very well there. I've set all the D5k's to small 96/24's and have the sub configured as mono. Crossover is currently 45Hz but has been 40Hz. It seems about the right level. I calibrated using a Radio Shack SPL meter and have spent a few evenings - not enough as work got in the way - listening to the system. I have some music that I play a lot to help hear the effects of change: one is Saint Saen's Organ Symphony and another is the soundtrack of 1492 by Vangelis. Other CD's that have taken a bit of a hit include overtures by Wagner, Leftfield's "Leftism", the Matrix Reloaded soundtrack, piano concertos by Beethoven and most of the Jonny Cash American recordings. No, I haven't slept much...

So, the position to date: The system sounds wonderful. Most of the time I'm unaware of the Stadium specifically but am very aware of a strengthened and heightened sound stage. There seems to be yet more detail and clarity but no "tightness" - it's something I think Nick hinted at in his experoience with D5k's.

The Stadium is clearly apparent when it contributes beneath the D5K's and it really is impressive. I played the opening scenes of Gladiator (until the Management Committee confiscated it) and it's truly stunning. Overall, I feel I've got a fairly seamless integration.

I know from the posts on this thread that I have a heck of a lot to learn - including how to adjust SPL levels with the meter held away from my body, the Meridan remote one handed and not much support from the above mentioned MC. How can Meridian design such stunning equipment, be so cognizant and invest so much intellect and competence in software and not employ or consult an ergonomics specialist?!

I'm getting there with set up but have a way to go to feel in command of SPLs and Phase. Mudge's comments were interesting in that regard. I'm going to try a few more subs before I buy. One though was to try two smaller ones to go with the mains but I now intend to go for one larger one. I'm looking for real authority and presence underneath the D5k's with the kind of music I've mentioned above and a lot more besides.

The Rel Stentor 3 is on my list and, if possible I'll try the Martin Logan Descent. Does anyone know of Genelec's subs? Living in Finland, it's sensible to try them. Their brochure shows a model 7070A but it is not on their web site that I can see.

Thanks again to all. It's a lot of fun when music sounds this good (and you know it can only get better).
