Your musical experience and listening tastes, which I happen to share, would be best served by a monitor of the BBC heritage as they really do voice right. My suggestions, which are just out of your budget, typically, are Harbeth or Spendor. Many sound engineers have to spend hour upon hour with their speakers, and both of these have proven themselves to be accurate reproducers. I highly recommend that you squeeze everything you can out of your budget to get this kind of speaker. If not possible, the PSB line is a very good cost performer. When you turn back to electronics, buy NAD, and never look back. Ignore advice on cables and interconnects.
Best of luck,
Charlie
