This is as good as I can do without spending signifcantly more cash.
The projector is a mitsubishi xl5u - very bright xga res lcd projector.
Front pair of tannoy m3 driven by thier own old but very hi fi mono power amps with ultrs short speaker cables.
No middle front speaker - vocals are good so no need.
No sub - the bass really is deep and tight.
Rear pair are Gale 4040 driven by the s sound amp.
Surround preamp / amp is a huge sherwood thing that was £500 new.
Screen is 1 to 1 gain ( bright projector ) and cost £130.
All video connections by component.
All audio connections with decent cables.
A few tweaks still to do. Some black velvet curtains to go up to stop light slap.
If I had the cash I would think about a better bespoke mount for projector and maybe another pair of tannoy m3 speakers so the rears match the front and another musical fidelity power amp but run in stereo mode for matched rear amplification. The dvd player really is temporary too - £23.95 from tesco - I am sure it is the weakest link - lols.
Trust me - if you have the room ( it owns the room totally ) this really is the only way to watch films.
