I have a Denon 1800 and I compared it to Onkyo and Yamaha
and found the prices to be very comparable to the specs.
(I live in the Toronto area)

I chose Denon over the Yamaha because of 5 channel stereo,
which is great for everything not digital and over the
Onkyo because of the complaints of their quality.

I am very happy with my Denon but everyone has their opinions about equipment.

I listened to the Epic 80 system at a dealer in Oakville
and was very impressed with the clarity of the M80s.
I will be purchasing the Epic 80 system very soon.
