Blindjim...the is blind willgolf. Please don't make the same mistake I made. I bought Mola Mola Class D amps prior to knowing what speaker I wanted. As soon as I picked out the speaker I knew the amp was not going to work well. I believe a speaker is critical first step. I ended up getting 98db speakers so super easy to drive. I basically gave the Mola Mola Amps away for a new Tube amp.
I believe you are aware of Raven Audio. They make an assortment of integrated tube amps from $2.5 to $14k. I had a Raven Reflection MK2 tube amp that was incredible. You can get a Blackhawk for half of your budget and never need another Amplifier. Call Dave Thomson at Raven.
If I were to go SS, I would definitely consider the Luxman line in your price range.
My buying order of preference would be Speakers, Integrated Amp and then DAC / Streamer. I just travelled down the journey you are on. I am now in the DAC phase and just ordered a Lampizator Pacific, so my much lover Lumin X-1 is for sale.
Good luck!
