I'm also a big B&K fan. The other brand that may meet your criteria would be Conrad Johnson, but they will be somewhat more $ for comparable power output. For example the CJ MF2100 is a 100 w/c and they generally sell for $450-550. This is a 1995 vintage amp. The newer models MF2250 up the power and sell for ~$1000. Go to the higher power units and you're pushing $2000 for 200 w/c. The CJ 5 channel offering MF5600 is 125 w/c and sells used for ~$2000+.
I had a B&K AV5125 (predecessor to the Ref 125.5) and it was a wonderful amp. I only sold it because I went to B&K M200 mono blocks in my home theater.
