You can certainly spend your budget on speakers first. You will have a lot of fun initially. Then, especially if you have not heard them before you purchase, one thing may happen, and a second thing will certainly happen, not necessarily in that order.
What may happen is that you discover (after the novelty wears off) that you don't like their sound as much as you thought you would. Sound systems are meant to be listened to in the long term, over months, and in that long a time you notice things that you don't notice at the very beginning.
Or, of course, it may happen instead that you find you love the speakers' sound more and more as time passes! However there will be a limit to how much your love can grow.
This is because the other thing, which definitely will happen if you buy speakers at a much higher level than your upstream gear, is that you will begin to hear very clearly the failings of that upstream gear.
Now it is a good idea to spend as much as you can when you upgrade any piece of equipment, because upgrading is always expensive, and when you move up a lot you have a chance to stay happy for a long time. And of course if you are currently using a piece of gear which is toxic to the ear, as your Bose bookshelves may be, then that piece of gear should go a.s.a.p.
But if you spend all you will have to spend for the coming year on new speakers now, remember that for 12 months you will be listening with great clarity to what is currently feeding the Boses. Depending on how you feel about that, you may want to spend a bit less on speakers now so you can get a better amplifier more quickly.
