best budget amp/preamp for B&W 805 D3s


you kind people helped me along the way. here is another question. I am happy with my setup but can’t help but think forward. Have an old Rotel RA 1070 that now powers my new 805s. I use, per your suggestion, DAC (Shiit Modi) to stream Tidal from my Mac. Sound is great but gets a bit choked up (crowded?) when the volume is turned up loud. my question: I have only $1k budget for a new integrated amp. 1) In that budget is there a significantly better amp or amp/preamp combo? 2) Should I wait until I have more $$$ to buy? 3) what budget integrated amps (amp/prem) go well with 805s (other than Rotels)? 
I don’t mind getting used equipment. Please, give me suggestions also for budget amp/preamp combos.
I very much appreciate your willingness to help. I am new at this and not an engineer.

You may try Schitt Freya pre and Crown Xls 2502 to drive your speaker.

I drove power hungry Raal Sr1a headphone by Crown Xls 2502 with good result.

It sounds very fast and exciting without hot edge.

But Freya will give some warmth to the sound.

You can also tune the sound by tube rolling in Freya.

RCA gray bottle 6sn7 will give warmer sound while Sylvania GTB made in 1950's give more neutral sound.

Even with the cost of Nos tubes, total will be around 2k$.

I have only $1k budget for a new integrated amp.

As I mentioned above, is in your price range new. And you can send it back after a good week of listening if not happy.
