Thanks for the compliments everyone.
It's been 6 years or so since I first posted this and my system has changed somewhat but the room remains the main player in how it all comes together. I haven't really touched the room aside from moving the acoustic panels around (or adding/removing them) as the system or my musical tastes change; they really can affect the balance, soundstage and 'intimacy' in there.
The wood roof panels have proven nice to have too; they aren't as easy to get behind as a suspended ceiling but I have pulled the trim strips and panels down in areas to get at the wiring and run network cables – a little messy but reasonably easy to put back up.
My system in those old pictures has certainly evolved; I now use a VPI turntable, ZYX cartridge, Sonic Frontiers phono-stage, Joule Electra pre-amp, Audio-Note DAC and Accuphase tuner, the Altec crossovers are now diy Markwarts. Some things remain the same though and my love-affair with low power SETs, Altec 604s, the Sony 777ES SACD player and vinyl in general remains.
This picture is much more recent and shows a a more crowded, jumbled state where I was messing around with Tannoys and a Scott tuner; I'll be getting back to my simple 2A3 or 300B/Altec based system soon though, as I find I like that combination best in this space.
