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.

There’s a NuPrime IDA-16 available here now for $1195, and if you’re after clarity and detail — along with a lot of other positive attributes — you should be very happy.  And 200Wpc should help your 805s wake up and get rid of any congestion at higher volume levels. It’s also got a very good internal DAC that may well be better than your Modi, and if so you can sell it and offset some of the cost. If I was you I’d jump on this ASAP.

I do not know how you will get a quality integrated for $1000 which will nicely drive your B & Ws.  B & Ws require quality amplification and are finicky with electronics to boot.  A budget expansion is required in my opinion.  Good luck!

For quality sound, B&Ws need to be driven by very low output impedance (aka high damping factor), and high max output current amplifier (> 50A), which rarely can be found in integrates ($$). Less costly option could be an appropriate Power Amp, and then finding better preamp. Class A, with minimal load of 2 Ohms is a good start to look for amp4bws. It could be A-70 Accuphase, or Pass alike.

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$$$
