JohnK,
Thanks very much for your comments. With my Denon 1804 having no problem with M60, how about the VP150 which is 6 ohms?. I hope no problem as well. The size of my family room is 15'W x 20'L x 20'H (vaulted ceiling), and open or adjacent to the kitchen area which is another 15'x 20'x 8'. Any thoughts?

I hope no issues here. It not, this will put my mind at ease since I just bought the Denon 1804 3 weeks ago (just before I came accross the AXIOM speaker system on the internet, and got hooked by the rave reviews and experiences of the owners ever since.)

Regards,
Rogel
