    Speaker Recommendation

    Some can be found. In this case, Legend are in Nowra, which is on the train system. Also two dealers in the metropolitan Sydney region. http://www.legendspeakers.com.au/ There are a number of suitable speakers in the Legend range, if you want to consider Australian. I believe the Axis Voicebox (or its successor?) is still available from Len Wallis. (I'm not sure where that is manufactured though). They also have a new Duntech model, though over twice the price the OP quoted and not suitable for the room either. Orpheus are still in business in Lugarno, and I believe without looking that there are two or three other Sydney manufacturers still out there. Hard, yes, but not impossible. In the case of Legend, at least, definitely worthwhile.

    Religion, Politics and Economics?

    @Marc ? Best get this answered and the thread locked early...

    Oh, is that all?

    DOLBY ENTERS THE HEADPHONE HARDWARE MARKET

    Thanks, I'll look into that.

    Religion, Politics and Economics?

    I see that: the politics forum is open again: it is now called Religion, Politics and Economics: the "why we discourage discussion of religion" article is still there Can I ask, apart from the mixed message, what the rationale behind reopening this can of worms is? Even though I was (and will no doubt be able to resist being) a regular in the Politics threads, it seemed to be more trouble than anything else: it descended into abuse and on occasion nasty racism among other things.

    DOLBY ENTERS THE HEADPHONE HARDWARE MARKET

    "Immersive cinematic sound" - stereo Bluetooth signal/DSP/some trickery to move the image when you move your head? Variable noise cancelling sounds like a good idea ("LifeMix") but these are still Bluetooth only stereo headphones under all the blurb. I was kind of hoping for a properly done surround headphone setup when I saw the page, but it just looks like marketing speak. Shame. They probably do what they are designed to do really well - but a claim of "immersive cinematic sound" from the company which licenses Dolby Headphone and owns key surround standards really implied more to me, anyway, and these may be set up to disappoint as a result. I'd be genuinely interested in a wired headphone with LifeMix or similar technology, maybe in 2019?

    Let's talk jitter.

    I believe we are talking about the input and output of a DAC here, prior to amplification. I'm not sure the amplified result would be audible either. We got into this because of idle speculation (from me) that it might be possible to tell something about jitter from the reduction in the peak of the sine wave. As so often, I've been corrected

    Let's talk jitter.

    So you would need impossibly good equipment to do that... got it.

    Let's talk jitter.

    Fair enough. Is there any other reason that the peak signal would be reduced, though?

    Let's talk jitter.

    I have vague memories of measurements of early products showing sidebands that I now know can be caused by periodic jitter. I'll try and hunt something out. I guess it would be pretty surprising to see this in any competently designed product, though. I found it an interesting theoretical example anyway.

    Let's talk jitter.

    But it has to be a graph showing the effect over time. An instantaneous measurement doesn't help, for example, with periodic jitter where you won't see the sidebands on both sides unless the data shows the dB effect by collecting samples over the whole period. So a graph showing a cumulative result over a large number of samples is needed. And from that, with the right information you would be able to tell some of the timing information - the sidebands would indicate periodic jitter and could give the timing of the period concerned by their placement, artefacts could give information about the nature of "random" jitter or other timings if you have enough information to translate those findings into time as well. I think @rmpfyf covered this in a previous post. The other thing to remember is that some noise will be present in any dB measurement of jitter - we may not know the extent to which jitter is suppressed, though since jitter artefacts are a redistribution of energy, we can perhaps tell some of that with a simple measurement of a sine wave by looking at how much the peak measurement at that frequency is reduced. There's more than just dB in that graph, and that is one thing I've picked up from this thread.

    How variable is your mains voltage?

    Thanks. Glad to hear of positive experiences!

    How variable is your mains voltage?

    I can't comment for Victoria, but in NSW it appears that you can have problems with complaints if you are with a different provider to the one that supplies the meter. We get encouraged to shop around for the cheapest deal but there can be consequences...

    How variable is your mains voltage?

    When one string is out rather than all of them, certainly...

    How variable is your mains voltage?

    My question was about changes to the sound of the system. Obviously, no sound is a pretty major change though
