Will you be paid in pounds or Canadian dollars after the move?

I'd wait until you get to Canada. There are a plethora of US audio dealers who sell to Canada. In addition, there are many fine audio dealers in the Montreal, Toronto and Ottawa areas.

Rotel dealers in Ontario
Find B&W dealers in Canada
Toronto ProJect dealer

Buy in Canada...in addition to saving the cost of shipping, VAT is better in Canada and I would bet the purchase price less.

You will find it hard to find internet pricing for Rotel as it is their policy to not provide it and will reliquish dealer privileges for those who do. B&W products are generally not available through mail/internet order although there are some discount places that have them. I agree with JIMV, you can wait until you get to Canada for your purchases. You shouldn't find it difficult to purchase that equipment once you get there.

The B&W 685s will go for about $800CDN a pair and the ProJect will be around $1,200CDN.

How long are you going to be in Canada (temporary, semi-permanent , permanent?) If it's going to be a while I'd recommend buying in Canada. That way you don't have to get the power supplies converted for the different electrical system. Not as small an undertaking as it may sound. Voltage converters meant for your electric razor are completely unsuitable for Hi-Fi equipment. The reason that you aren't finding prices listed on the web is because most high-end manufacturers discourage their dealers for engaging in the practice. They want everyone selling locally. Plus the price will vary from country to country (less so with B&W/Rotel because they handle their own importing.)

Buy a nice set of head phones to tide you over.

US internet based dealers (most should sell into Canada):

http://www.audioadvisor.com/ They always have sales on demos and discontinued products

However it is near impossible for an phone/internet outfit to add the same kind of value as a local dealer. No matter how hard they try. You might find a local dealer to be of great assistance when it comes to getting into the hobby and putting together your first system (if this is your first.) Help narrow the choice in the equipment by asking the right questions, hook up different combinations of equipment to let you know what to expect, and even for a small charge install everything for you. Sometimes it isn't what you buy, but who you buy it from that makes the difference between being happy with a purchase and regretting it. Dealers are a great resource and are well worth a little more money than what you'd save buying on the internet, especially for beginners.

There's nothing like listening to gear before you buy. Reading reviews should only be used as a way to make a list of "possible" purchases, not for making a shopping list.

That item does not appear to be really available on this side of the pond so I cannot compare prices for you.
