I followed the advice of member Johnk and I am now using 350mcx Krell monos with Sosna Emotion xlr and Valhalla speaker wire.
The speakers have enough power to get my room to 90Db (plus peaks) from 9 feet away using the Radio Shack C weighted meter without compression. I love that Krell grip on bass and mid bass and it is pretty smooth.
I have the clsIIz with bybees and internal speaker wire Au24. Anyway, good luck on your efforts.
