Let's assume it will drive two way speakers with 1" tweeter and 8" woofer, 89db 8ohm. Any price level. No hybrids invited. I personally haven't heard of one.
Depends on how much flexibility you need for the "integrated" part. I had a pair of Air Tight ATM-2 monos, which included two inputs and a volume control - so just enough if you use one digital and one analog source. They certainly had real bass and could drive your proposed speakers with no issues, but would probably run you about $26k today.
