Welcome indeed Jim!
From one cold place to another, I am writing from Fredericton, New Brunswick. It is -15C and we are expecting 15mm of freezing rain over the next 24 hours. Should be interesting. We have plenty of firewood, food and beer, so I say bring it on!
Sound like quite an adventure bringing your gear across the pond, and converting and reconverting the power supplies. The things us audiophiles will do. I recently moved from the west coast, in British Columbia, back home to NB - and hauled my gear along with us. We only had a 12 foot trailor and I'd say 25% of it was occupied by boxes and boxes of audio related gear! Thankfully, after 9 days of driving and 5,600km's later, all components survived the trip safety.
Those ATC active speakers look lovely, and your setup must have nice and clean appearance. Got pics?

I'm running an all-Bryson setup....MiniT speakers, 4BSST2 amp, BP-20DA preamp, BDA2 dac, BDP-1 digital player and BIT20 power conditioner. Often times, I will switch out the Bryston MiniT speakers for PMC Twenty 22's. Oh yea, and for added low extension, i'm running a REL328 sub.
Prior to using Bryston's BDA2 DAC, I was using the internal DAC in the pre-amp, and before that a Marantz pre-amp/DAC.
I have to say the BDA2 DAC blew me away the moment I plugged it in and hit play. Super clean and transparent. The DAC has a ton of input options - including balanced in/outputs. Bryston introduced a new BDA3 recently with HDMI options. If HDMI is not required, the BDA2 provides the same sonic signature as the 3 without the added costs. (IMO). I believe PMC is the EU Bryston distributor, but i'm not entirely sure on that.
Anyway, as you can see, I'm a huge Bryston fan - and i bet their DAC (and preamps) would sound amazing with your speakers.
Your home office setup sounds really cool!

ps. i've been lucky enough to visit Glasgow, Edinburgh, and St. Andrews back in 2008. Gotta get back there someday!
