Then IF that were my goal I would strongly consider the speakers as the first but certainly not the most important component. Because equally important are the speaker cables, amp, interconnects, power cords, source components, and tweaks like room treatments. It all works together. Neglect any one over the others and you will pay. Big time.
What this means in real terms is a system with $3k speakers is going to be about a $15k system- with the remaining $12k being something like a $4k tube integrated amp, $4k turntable and phono stage, and $4k power cords, speaker cables, interconnects, room treatments. Ballpark.
Done right that would be one stellar, blow your expectations right out the door, impress all your friends system.
But you should also know that quite honestly taking the same approach you would be shocked how much better than what you have now you could get with just the $3k for everything. All-in. Just to drive the point home it is not what you buy but how you buy and what you do with it that matters in the end.
