Recommend an amp + pre for ESL 57s and a new turntable (way out of my league)

Hi all, longtime lurker now starting my semi-serious venture into all of this. I was recently gifted a pair of Quad ESL 57s, a Well Tempered Labs Amadeus GTA turntable, and a Miyajima Labs Shilabe cartridge. I need a preamp and amplifier for the system on a budget of ~$1000 - $1500. I currently have an old Harman Kardon Stereo Festival (TA-230) receiver, which is just a cool piece of old, barely working, shits-n-gigs gear I used to drive some junky speakers with in college. It hasn't been plugged in in two years and even if its still works, I don't think it's a great match for my system. What would you recommend? I am most interested in listening to some old mono blues, jazz, and folk LPs I have, and I imagine most of the records I collect in the future will be similar (I know I have a stereo cart, which I've always understood to be fine for this?).

Some guiding questions:

- Seems like a favorite for the ESLs are a pair of heathkit UA-1s. Another that I'm seeing well recommended is the Dyna st35. Thoughts? Does it make sense to spend ~$700 - $1000 on a nice amp and get something more basic for the pre in the $400 range? (Rega fono??)

- Should I get a nicer preamp to match my cart and go with something more basic wrt amplification? Not sure what is good in the way of cheaper(?) amps to drive these speakers.

- In the event that I stretch my budget and wait a bit between buying one and the other (to save back up lol), would I get more out of a ~$1200 amp and the cheapest preamp that will work, or a ~$1200 pre and the cheapest amp that will work? What would the cheapest preamp and amp that "will work" be in the meantime? What would be in the $1200 range for each, respectively?

Thank you if you took the time to read this! I will be cleaning the dust off the Quads in the meantime.
