  • Is this an upgrade from a Yammie RXV1400? Had it for ages but haven't found anything that matches its grunt for a deal as yet

  • Do you get the free pair of SKH-410 Dolby Atmos Enabled Speakers with this amp, that onkyo was offering

  • Given Airplay is via an external DS-A5, what is the cost of that?

  • Oh dear.


    An impressively specified receiver, but its sound performance leaves us wanting

    Sony STRDN1050 7.2ch 4K Upscaling Network AV receiver $839.30 JB


    Product of the Year, Awards 2014. A seriously good amp that balances muscle and subtlety with stacks of features at a great price. Sony raises the bar once again

    • Probably worth mentioning that What Hifi reviews have been terrible for the last few years. They are treading a fine line between appearing objective and pleasing their advertisers, treading the wrong side of that line imo.

  • Can somebody help me out?

    I bought a cheap Philips HT system a month or so ago. The receiver is useless due to having only the one HDMI input. So I'm looking to at least upgrade the receiver first (not necessarily this one), but the "plugs" for the speakers don't seem to match this. Are the speakers incompatible? If I pull the wire out of those plugs, would I be able to use them with another receiver? I plan on upgrading the speakers eventually too, but one step at a time. I've attached some photos of the plugs or whatever they're called.



    • The speakers except the sub will be compatible.

      Option 1: Cut off the plugs, strip off a bit of plastic and use with a normal receiver. Disadvantage: Irreversible.

      Option 2: Are the wires detachable at the speakers end? If so then buy a roll of speaker cables and use that to connect. Advantage: Custom cable length, easily reversible.

      The sub is probably an el-cheapo passive unit. Normal receivers require an active sub (one with its own amp and power supply).

      Option 1: Buy an active sub.

      Option 2: Find an amplifier for the passive sub.

      • Thanks a lot for the advice. I'd be buying a new sub eventually anyway so I'll probably get one when I buy the receiver.

        I'll check if the wires are detachable on the speakers, otherwise I might just wait and get everything together as I was planning on reselling it eventually. That might be difficult if I mess around with the wiring.

  • A fan in an amp is not a positive selling point.

    In fact, quite the reverse.

    Also, onkyo has gone down the toilet in recent years. No longer made in Japan and there is almost nothing proprietary anymore.


    • Very few AV receiver are made in Japan these days, Inkel electronics and Anam electronics build the majority of AVR's on the market now days, even supplying AVR's for most established brands, i.e Denon, Marantz, Pioneer, NAD, H/K, Anthem, Yamaha all have models supplied by those ODMs.

      Though I do agree Onkyo's quality has dropped a lot in recent years.

      • Yes, Very sad. I said that with a lot of love, as I used to be a hardcore Onkyo "fanboy".

        Yes, most not made in Japan anymore. Mainly because the masses favour new over quality. That is OK, I only need 1 special receiver, not most receivers.

  • I have had two previous Onkyo mid-range amplifiers for the last few years and both had major issues with overheating and random HDMI outs. Went to a Sony and couldn't be happier. Really hope Onkyo have got their sh-t together because their last few series were more than disappointing.

  • I bought this model last week. Very happy with it so far. Great feature set, and a very nice sound.
