608 Power Consumption

Level: Watt Draw(Movie Music) Watt Draw(Load Music) Watt Draw(Vocals Only)
-50 62 66 61
-40 64 70 63
-30 65 73 64
-20 68 81 65
-10 69 90 66
These were all an average of three readings after repeating the exact same 30 second clip and taking in the highest output displayed. There was one variation on the -10 where it hit 110 so I did another few on that but didn't see it again.
This was so loud my wife left the room yelling at me, -20 is about the max I would stand on a regular basis.
A. Amps are rated (capable) of much more than most people will ever use.
B. The Onkyo is NOT a power hog! Though the Pioneer may be even less of one.
C. Regardless of RMS, AC, DC, etc. the Onkyo is not what I would term inefficient with an A/B amp.
Back when I did pro car audio, nobody would use a class D amp for anything but subs, they sounded like crap, I'm guessing that has changed, but has it changed enough that a class D can sound as clean as an A/B? That's something to consider.
The meter showed 0watts when turned off, meter doesn't show 10ths, and 59 when on, so it does use quite a bit when on with no sound.
Edit: Had a typo of 70 instead of 90
Here is what I take away from this:
The Onkyo at reasonable listening levels uses between 61 and 81 watts (61 is -50db vocal only, 81 is -20db thumping R&B) and at ear splitting volumes it uses between 66 and 90 watts (-10db, vocal only and R&B).
In the Onkyo manual it states it will draw 34 watts in standby mode (that is the hdmi circuitry draws 34 watts when the amp is off).
Therefore at reasonable listening levels the 608 amp uses between 27 and 47 watts and at ear splitting volumes the amp uses between 32 and 66 watts.
These conclusions are for michaelahess' real world measured system, so they apply to his room and speakers and probably vary for other people, but its nice to see a real world data point.
So if we assume the Pioneer is twice as efficient as the Onkyo then at reasonable listening levels michaelahess could be saving between 13.5 and 23.5 watts or at earsplitting levels he could be saving between 16 and 33 watts.
Sweet, we've put real numbers to this so people can make an informed decision between the Onkyo 608 and Pioneer 1020 -- now we can stop talking about that in this thread.608 compared to Pioneer 1020
Here is a summary of differences:
-608 has THX certification and listening modes
-608 "wastes" between 13.5 and 33 watts to a less efficient amp
-608 has 100 watts of output power vs pioneer's 80 watts
-608 has Audyssey 2EQ vs MCACC in pioneer
-608 has Audyssey Dynamic Volume and Dynamic EQ (does pioneer have similar?)
-608 has an optional ipod doc vs pioneer ships with usb cord to hook up to ipod
-608 is warmer than 1020, but so far there has not been any report of the 608 being problematically warm (it could be an issue if you place the 608 in a closed compartment with little to no room on all sides (which might also be a problem for the pioneer))
-608 remote is programmable, pioneer remote is learning
-608 has no networking/internet radio, pioneer does
-608 has OSD volume overlay, pioneer does not
-608 can access all setup features though OSD, pioneer does not
-608 has HDMI ARC, pioneer does not
-608 uses Faroudja video processing, pioneer uses Anchor Bay
More info on 1020 vs 608 (I need to condense and reorganize this post...):Ipod specific differences:
608 will not show album art even with the dock. Just text. 1020 does show album art, and its supplied cord can be plugged into regular Apple dock. Also important here is list of supported OSD languages - neither model will show ID3 tags for songs if they are not in one of languages supported by that model's OSD. The list differs between Onkyo & Pioneer. English-speaking crowd probably does not care, but for people who have songs in different languages/tags, it is pretty important.Pioneer HDMI reassignment quirk:
Pioneer does not allow HDMI inputs to be reassigned if you have HDMI-CEC enabled. That makes it nearly useless, because 1020 will keep switching to "TV" input if HDMI-CEC is enabled (and you can't tell it to use HDMI for that input). It's probably one of the most annoying/illogical/self-contradicting "features" I can think of. Disabling HDMI-CEC is what most people end up doing, and with 1020 that means no volume indicator on TV screen, since it has no OSD overlay.Remote differences:
Onkyo remote has no "sequencing" capability, Pioneer's does.
Onkyo remote has one unusual feature - there is no dedicated power button for the receiver itself. Most brands have that, so you can turn receiver on/off regardless of what input is selected. With Onkyo if you select an input, your power button is no longer working for the receiver. Have to press "receiver" to get it back.
Pioneer's remote has no dedicated buttons for all HDMI ports (except BD port). Have to cycle through by pressing (one) HDMI button. Not too bad if you can reassign them, but see above about HDMI reassignments limitations.
PM me if there are other difference and I'll add them to the list so we can just point people to this post and be done with the 1020 vs 608 issue.
