True, but that's with the Speaker Impedance set to the 4 Ohms selection!
...And it does indeed reduce the heat, the power consumption, and also it recuperates much quicker from voltage shortage in situations of clipping! ...As opposed to drained current!
And from Home Theater Lab Tests, the 805 produces 327.6 watts into 4 Ohms, with two channels continuously driven (for 0.1% THD, and at 1 Khz).
Into 8 Ohms, with seven channels driven continuously (0.1% THD, and at 1 Khz), it was delivering 120.4 watts (RMS).
At 1% THD, it delivered 151.7 watts!

At street prices, they were a grand theft steal!
* Now with several receivers having 9 internal power amps (Denon, Onkyo/Integra, Yamaha), a power limiter is implemented.
Even some (actually many) 7-channel receivers have a power limiter!
But then, those are not used in high end Home Theater rooms either! Very seldom you would notice a lack of dynamics!
...Until........ you switch over to some Emotiva amps!

Still though, it amazes me to see the results of excellent overall power from receivers by Pioneer that cost only $500 and weight less than 25 pounds! ...And some Marantz and Denon receivers as well that weight just over 30 pounds!
Look at the power figures of those Pioneer Elite ICE receivers!
The SC-09TX for example!

And their sound quality is getting better and better each year!
SC-25 & SC-27, SC-35 & SC-37...
For normal size living room, can't ask any better than that!
For larger and dedicated HT rooms; then Emotiva amps come to the rescue!
-----------------------------
Recipe for a good amp design:
1. Large power transformer (EI core or toroidal).
2. Large number of matching high current power transistors.
3. Large suface area from quality heatsinks (solid aluminum).
4. Large wire gauge used all around.
5. Several caps totalling large microfarads capacitance.
6. Quality circuit boards with quality parts all around.
7. Quality materials used thorougfully.
8. Thick and solid metal or aluminum face plate.
9. Solid chassis (top, sides, bottom) with no ringing and rubber absorbers at strategic points.
10. WBT speaker posts and hexagon screwed and secured RCA jacks, as well solid XLR jacks.
