Then 1.5k for some used floor standing speakers would probably do some Paradigm studio 100 or old bw or kef or a perfect condition Psb stratus gold i
And then drop a grand on a grace 901 dac and a decent dvd/br player. I think you could have an amazing system for 5k. My biggest advice is go older full range on the speakers and ice amp integrated for the amp! Good luck!!!
Oh yeah and blow a couple hundred bucks on some decent headphones
Akg 701 to go with that dac/head amp!
