Before comparing HK receivers to others, two things to keep in mind.
1. They specify all channel driven power output. They have also started providing 2 (Stereo) channel driven output numbers. That being said, in a couple of bench tests that I have read, they actually produce lower outputs in 1, 2, even 5 channel driven tests than competing (in terms of price) Yamaha and Denon products. I would love to see the 147 bench test against say a Denon 1508. I would bet the 1508 has higher 1, 2 channel output but in par or slightly less in 5 channel driven output.
2. If you are in Canada, they are not really that affordable, e.g. $899.99 for a 347, and the last year model 146 now on sale for $349.99 ($449.99 before sale). That compares to the Amazon.com prices of $223.95 for the 146 and 508.95 for the 347. So be careful Canadians!
