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.

best budget amp/preamp for B&W 805 D3s


Stereophile:
"The B&W’s voltage sensitivity is specified as 88dB/2.83V/m; my estimate was slightly higher than this, at 88.4dB(B).
The nominal impedance is 8 ohms; the solid trace in fig.1 reveals that the magnitude drops below 8 ohms between 100 and 750Hz and above 8kHz, with minima of 4.6 ohms at 180Hz and 22kHz.
The electrical phase angle (fig.1, dotted trace) is occasionally extreme, with combinations of 6 ohms and –35° at 118Hz and 8.2kHz.
Tube amplifiers will probably work best with this speaker when used from their 4 ohm output-transformer taps."

I would for budget amps look at the Schiit Aegir Class-A if you don’t listen at really loud levels, or the Schiit Vidar if you do.
And mate it up with a $49 Schiit Sys Passive or Freya preamp for extra$$$

I have only $1k budget for a new integrated amp.
Uh, the spec you left out re: the H390 is that it retails for $6k.  Has your budget changed that significantly?

no. but used are half 6k. and deciding on an integral amp simplifies my process. when you are new at this, options are just overwhelming. thanks again.
