I am currently using a Sherbourn 7/2100 which is 7x200 into 8 ohms and I believe 300 into 4 ohms. Running this into my Dali Euphonia MS4's and I can tell you that the Sherbourn never runs out of gas. Sound quality is quite excellent and probably one of the best values for the money on the market for a multi channel. At full retail new they are around 3k. You should be able to get a good deal on a used one around $1700-1900.
Best of luck in your quest.
