Understood. You have gotten many different opinions but for the most part it seems that any decent receiver will work fine.
So, since you have always been leaning towards separates and obviously have plenty of money why not just spend $1000 on whatever it is you want. I get the feeling thats what youre gonna do anyway. Buy something that you can return and see how it sounds. Everytime someone suggests something you just suggest something else anyway. If you are waiting for someone to come along who has the perfect solution that absolutely cannot be debated then you will never buy anything. Youre speakers are not special in any way. They arent even some kind of expensive exotic or anything. Just basic, run of the mill, midpriced bookshelf speakers. Theres no reason to search the world over to find something to drive them.
But you have already been told this by several people here so Im just wasting my time. Good luck.
Why dont you call B&W and ask them what the perfect option would be? Surely you can trust them.
What about your audiophile relative? Is he full of BS too and cannot be trusted?
No, Mr. Bond. I expect you to die!
