    Hi Peabody. Whats Onkyo's measured continuous power output into 4 ohms? Just so youd know, I dont doubt that Onkyo can now drive 3 or 4 ohm speakers.....but so can a lot of AVR's who no longer need to list high current. But I do remember Onkyo had reliability problems a few years back from over heating of their AVR's. I suspect their receivers had problems driving some loads. That may be one of the reasons why they are listing "high current" while others dont. Just my speculation. Onkyo / Integra Research is a very good product.

    But most recievers are listing good number in dynamic power in 8/4/2 ohm loads, Power for all channel driven at full bandwidth 20Hz to 20KHz with THD < 0.1%. Good numbers in these areas may tell us something about how good the power supply is which delivers that "high current". But hey man, lets not argue....I really dont want to get into it....if you disagree well, we can't always agree. Besides, you and I agree on a lots of things....so this is not that impotant.

    Here is my new Aventage RX-A710 which does not list "High Current" but kicked my old Marantz which did list "High Current" in the balls..My poor cell phone camera.

    This is what Digital Trends says about the power supplys in the Yamaha Aventage Home Theaters.

    "Much of what distinguishes the Aventage receivers are build quality aspects and layout design. For instance, the receiver’s power supply has been placed in the center of the chassis with the left and right amplifier circuits placed on either side. This permits a physical separation between the left and right channels. Directly under the power supply is what Yamaha calls the “ART” wedge. ART in this case stands for Anti-Resonance Technology. The idea here is that the fifth foot provides better isolation from external vibrations. Doing so is meant to make an appreciable improvement in sound quality but, on that point, we’re undecided. It’s also possible that placing a heavy power supply smack in the middle of the receiver’s chassis required some additional support. Just sayin’"

    But the manual says nothing about "High Current". But in home theater mode, it kicks the hell out of my "High Current" Marantz which has been moved to the basement Home thearter which had a old Sony Home Theater receiver that was really week in dynamic power.


    The article went on to say this about the RX-3010 which does not list "high Current at all.

    Once we completed a manual speaker calibration, we decided to put the A3010 through a pretty intensive workout right off the bat. Yamaha rates this receiver as “150 watts per channel” but, according to Yamaha’s spec page, that measurement was made with two channels only (albeit over a wide frequency range and with low distortion figures). In our experience, a lack of multi-channel output ratings is usually a sign that something is being hidden. So, we decided to lay the smack down on the receiver by queuing up J.J. Abrams’ 2009 version of Star Trek and cranking the volume up to near reference level.
    With so many bombastic scenes in this film, there’s no shortage of opportunities to make an A/V receiver wince. We took every single one of them in an effort to bring out the A3010’s raucous side but found that the RX-A3010 was able to hold together remarkably well. With all channels blazing, the Yamaha kept its cool, remaining dynamic and in control of the explosive presentation. We did feel as if some of the high frequencies were overly accentuated-a characteristic we would listen for while testing music later-but walked away confident that this receiver can deliver power on demand as well as similarly priced competition like the Denon AVR-4311CI.
    And while I dont have the RX-3010, my RX-A710 too, is able to put out high current, dynamic power when needed.
