    RRP $1499

    Your normal selling price is $1,149


    It is decpetive and misleading to make a price comparison to a price you don't normally sell for…


    • Your life must be really boring to care so much about the wording of an ozbargain post.

      Thanks for the entertainment though, was bored on the train then found this.

      • to care so much about the wording

        it has nothing to do with the 'wording' it has to do with misrepresenting the supposed 'savings'…

  • RRP stands for Recommended Retail Price, that is the price the manufacturer recommends you sell it for. It's the price on the shelf at JB Hifi.

    Did he write, we sell this for $1499, no, he did not and the website just has the price, not $1499 crossed out.

      Actually, it is $899.50 at JB right now.

      • Wow, my dad was literally looking at this exact amp yesterday and it was $1499 at JB. He even sent me a photo asking if it was a good price lol, thanks for the heads up!

      RRP stands for Recommended Retail Price

      We all know that, but the law does not allow for misleading price comparisons when you do not normally sell at that price…

      Why else would you state the RRP in the title if it wasn't to compare it to the price they are selling it for???

      • Doubt he's breaking the law, which was essentially set up to stop misleading claims of x% or x$ off, half price etc. He has simply shown his price V the mrrp, with a bonus of free delivery.

        Had he posted 40% or $600 off based on the rrp rather than Rio's usual selling price (which can fluctuate) then he'd certainly be in hot water. To placate critical eyes he could have mentioned that this price is $254 off their normal discount price, which sounds like (caveat emptor) a decent deal.

          Doubt he's breaking the law

          people have been prosecuted successfully for it…

          doubt a judge would find you guilty if it wasn't against the law.


        • The big saving is what is implied by putting up the rrp. That is, the goal is to mislead on perceived saving.

        • @jv: Nice try jv. You presumably know the difference between lemons and limes, apples and oranges? The linked case has no similarity to this post whatsoever. Harris-scarfe iirc was also prosecuted but on the basis of one of the ploys I'd previously mentioned.

          Some people require spoon feeding not much doubt about that but the question is should retailers have to be their nannies? For example should a retailer have to advise that car tyres are almost never sold at rrp, or that anyone paying rrp for expensive items should do a bit of research? This is essentially what the naysayers on here are suggesting.

        • @Possumbly:

          has no similarity to this post whatsoever

          yes it has…

          "Trade Practices Act 1974 by making false or misleading representations with respect to prices."

        • @jv: Here we go round the mulberry bush. There is nothing false or misleading about what was written. As I suggested above he'd do better to also add in their typical price so that those in nappies are protected from their own paranoia.

    • No he didn't say he sold it at that price but that's the general implication, if it wasn't then he would have written the price he sells it for but it wouldn't have looked as impressive, would It.


    This or the sony 1060 ?

    • Perhaps read the What Hifi review of this unit. Their opinion: if you aren't going to buy the extra speakers for Dolby Atmos then the Sony 1060 is likely the better buy. Only technical point in favour of the Onkyo is it has more HDCP 2.2 inputs. Final factor is which one do you personally like the sound of better, which is of course subjective. I would go the Sony 1060 personally.

    • I would suggest this because of the support for Dolby Atmos and DTS X

  • Do Onkyo still make good stuff? (Just curious)

    • Read the What Hifi review. Say it's good but arguably not the best at it's price.

      • At its price of $1100? Or at its price of $900????

        I ask as I'm looking at upg my old Onkyo 606 for DTSx & Atmos.

        • Actually if that is your interest then this is a good unit to look at… I'm sure you've read the review by now but it's based on comparable UK street prices at the which while different, are roughly relative to comparable prices here… Ie the sony 1060 without atmos can still be had cheaper for $721/649 and this is the sort of value comparison they do. They also mention a pioneer for atmos.

  • Thanks for that, not really in the market for a new amp (I have the Yamaha RXV 3800) but Onkyo was a strong contender when I bought that. The next job will probably be speakers. Still have the Jamo 507's, they're only about 20 years old now. :) Have heard good things about the Klipsh RF-7 II's but at 5K a pair it's a long-term project.

  • Don't buy an Onkyo. Google "onkyo hdmi failure"

    From about 6-8 (?) years ago, Onkyo buried their head in the sand and kept selling units with hdmi boards that had known catastrophic failure rates.

    With changes to HDMI, hopefully the new hdmi board is unaffected by the same failure rate. BUT, Onkyo proved you can't trust them.

    Onkyo, no way. NEVER again.

    • Understandable. But my Tx-sr606 is still powering on well (jinx). Had a quirk of HDMI once, swapped the cables and devices on that port and now literally 6.5 days out of 7 it's on multi hours a day.

      I'd only look now to change due to DTSx and Atmos and I'd go Onkyo again.

      Though it's the old Apple/Samsung, Ford/Holden, Pepsi/Coke human nature thing I guess.
