RX-V750 or RX-V1400 for my new speakers

Hey guys,
I just picked up, sort of spur of the moment thing, a set of older Yamaha speakers...I don't believe they were released in the US market but they are avail. here in Canada.
At the end of the thread are the specs.

Now I'm looking for a receiver to match...I'm leaning towards either a Yamaha RX-V750 or RX-V1400. I spent $300 cdn on the speakers which was a little less than what I thought I'd have to spend...so I'm hoping to get a reciever for under $500 cdn. I saw a couple v750's for sale for around $375 US and a V1400 for around the same as well. My question is are these receivers any good? Will they match what I have now as speakers? Should I consider any other rec's? Thanks in advance...
