Typically it makes sense to go with speakers first - agreed.
However, depending on your situation (ie., when your amp is already outclassed), might make sense to deviate from the rule, especially if you are not planning on starting over from scratch.
In my view no HT receiver is satisfactory for serious 2 channel listening, however your $10k budget will likely not cover a quality pre/pro/power combo (new at least), never mind new speakers on top of that. Anything from Cary/Bryston/Anthem runs $10-12K, and forget the lower priced separates. It's cheaper to go for a decent HT receiver (I suggest NAD), and add a good 2 channel integrated with HT bypass for half the price.
Don't know the Merlins but have heard good things. Totems are OK (the Mani 2's are very nice), not a big B&W fan these days. Speakers are a personal preference - you have to listen to them and decide for yourself.
