Canadian here too. I'm fortunate enough to live just outside the downtown core in Vancouver. Don't like HiFi Centre much, but frequent Sound Plus (10 minute walk from home) and Commercial Electronics.
As a matter of fact, I'm going to check out the Ultrasone 650 Trackmaster at Commercial this weekend. My IXOS dj1003 cans look suspiciously like an Ultrasone product. I'll take them with me to provide a basis for comparison.
Regarding international shipping, the courier companies screw you royally. I did win once, though. Three years ago I bought a Thorens TD126 Mk.III online. It was shipped to my work (large hospital) and everyone was very confused as to who it was for, who ordered it, what it was and who paid brokerage on it. The brokerage agent became so confused over fees for a duty-free, "obsolete" personal item that she eventually mailed me a no charge brokerage release. Considering I'd already paid about $900 CDN in purchase, insurance and shipping, I wasn't anxious to pay more.
Cheers,
Graham
