AVR Power Output Comparison

I did by turning the volume knob clockwise to -3.
The Salons did the rest

My Salon2 don't even go above -20.0 or sometimes above -25.0 on some of my music because the volume here is 100dBC (in Pure Direct 2.2 mode).

I set my levels to 80dB, instead of 75dB.

Tnx..
Read the link..
However...
Very little info about their test criteria..
Emotiva raised the same point about AC line voltage and current draw. 1 thing I know is that when doing some amplifier projects with D&M, that in their testing lab they actually utlized separate 25 Amp AC lines just for measuring large component amplifiers as they discovered even large AVRs would cause a 4-5 volt drop when doing full power tests.. Though maybe not so crucial for many or a typical home theater system, published power output specifications are technically part of a product's warranty so the brand has to be sure the unit's real performance specifications. Also if the amplifier is sourced from an outside factory the power output specs are part of the puchasing contract..

Just my $0.02...

I agree they offered very little information indeed, but they do seem to use the same Audio Precision like others including EMO. They also hold the input voltage at 120V and confirmed they used continuous sine waves of 1 kHz. Any voltage drop downstream is the problem of the test object so I am sure that wasn't the reason why some amps tested not as well as expected. Actually I cannot recall any other amp tested by HTM that has not yielded higher output they the manufacturer specified. Further, the key word is consistency, take a look of the Outlaw amps they tested, their tested output far exceeded their specified outputs. That's why it is a good idea to compare the test results done by the same lab/people. In the case of HTM, at least they are telling people they can compare the results from one test to the next.

You know we're still waiting for someone to measure the $500 Crown XLS 2500. I mean if it measures 500 WPC into 8 ohms, 1000 WPC into 4 ohms, and 1500 watts into 2 ohms @ 1% THD, that would be good bang for the buck?

But in the end, my position is that we don't really need all that power for most mass market speakers - not 500, not 300, not 200 WPC.

Until maybe one day I can get an AVR to go into protection mode.

Is there a reasonably inexpensive way to measure the power being delivered to your speakers?

Are you selling your ATIs then?

NO. I need the AT3002 to power my two Funk subs and AT2004 to power my four Velodyne subs since I must have unpowered subs. I also need the AT6012 to power my Orion speakers and RBH subs. So I might as well keep my AT3005.

I measured voltage and current with my meters, the readings are quite consistent with the analog meters on the amp. I am sure the absolute micro second peaks are not captured but the mini second ones are. My 2 ch system speakers do not take much more than one watt, or a little more than a VA on average, typically fractional watts/VAs
