SX-1250, it led the way!

Here's a pic of the guts of the new Denon AVR-5805, the flagship at 6000.00
For the SX-1250 owners out there, it might look a tad familiar in the amp side, don't it?

haha, its rated 170 by 10 ! but draws a max of 1560 watts (13 amps) from the wall. So somehow it magicly CREATES 140 watts. Damn I wish I could come up with a 108.9% efficient amplifier. Obvioulsy it is not as powerfull as it says it is, and probalby doesn't sound better than my SX-1250 for music. Now I can't find the AC draw of the 1250 for some reason, but I have seen it before and I think its around 1200 watts at full output. Mine says 650 watts on the back, but that is idle power I belive. Anybody know ?

Home-theater receivers are always WeaselRated(R) one channel at a time. Hit rated output on all channels? Nope, and frankly, they don't need to. It is wildly disingenuous of the manufacturers, though. It's how we get "500-watt" receivers that draw 300 watts from the wall and cost $199, that our midlevel vintage 40-50wpc units stomp all over with no effort whatsoever. Denon makes a fine HT receiver, their upper-midlevel machines are a splendid choice for movie buffs, but spending $6000 on a receiver is silly beyond belief...you can get a good pre-processor and separate power amplifiers for that kind of jack! WAY too much circuitry in that thing...way too many functions in one box. That thing's gotta be a nightmare to service!

2x160=320. . . Amp draw of 650 is correct IIRC on the 1250. . . Idle is somewhere like 60-90 or so. . . .

Good point Todd ("our midlevel vintage 40-50wpc units stomp all over with no effort ") and for some real-life measurements, slip on over to the [Exclusively Sansui] forum and see what my 7070 measured this morning driven (both channels) into overload.

I have a Pioneer VSX-D606S H/T receiver. It's from the mid to late 90s I believe. It's rated at 130wpc (stereo). I can tell you without a doubt that my Kenwood KR-7400 has more power. I've actually had the Pioneer at "full throttle" through the Infinity Column IIs. I wouldn't want to be in the same room with the Kenwood doing that.

There are plenty of folks out there to buy these Flagship receivers. Big market. These guys just want a receiver. . . .

I use a Pioneer Elite VSX56TXi(1800.00) rated 110x7 (650watt consumption) but real world that would be 110x2. . . My old 1014 Pioneer(400.00) also rated at 110x7 but consumption was 480 watts. . . . My Elite is 20 pounds heavier, better construction and better heat sinks and shielding .among many other things like better componets etc. . .
