It's not going to be possible to get a good integrated or a preamp/amp combo for $1k that will satisfy your needs. If you really want something now, TMR Audio (on audiogon) has a used Classe Sigma Amp2 for $1084. Then just use the pre-outs on your Rotel to connect to the amp. The Classe Sigma is Class D 200 watts per channel into 8 ohms, which is a significant increase from your Rotel. It's also incredibly clean sounding and will not have any of that congestion when you turn up the volume. You can then upgrade to a better preamp sometime in the future when you have the budget.
If you want to wait and save up to get a better integrated, it's like going to be $2-3k plus. Some ideas are below:
Kinki Studio EX-M1
Hegel H160 or higher
Classe Sigma 2200i integrated amp
Luxman
There could be others, but those are ones that come to mind for a good match to B&W D3.
