  2. Where we are now: The site is back up and running! The character set encoding issue has been fixed so old posts should now look ok. I am currently working on themes/skins etc and I will be deleting the temporary green skin very soon as it has many issues. I will do a very quick variation on the stock blue skin first just to get a light-grey background and san-serif font, and I will set this as default. Later this week I will hopefully add a professional third-party skin in pfm colours (life is way too short to do this crap myself, and I've found one I really like than needs next to no tweaking). We are getting there slowly...

  3. May I please request people check and update their email address if it is out if date. I ask as I’m getting countless bounce errors as the server fails to send notifications through etc. I’ll eventually figure out how to send these to a black hole somewhere, but it makes sense to address it at source as quite a few folk are obviously not getting the thread and conversations notifications they have set in their preferences.

  4. Things you need to know about the new ‘Conversations’ PM system:

    a) DO NOT REPLY TO THE NOTIFICATION EMAIL! I get them, not the intended recipient. I get a lot of them and I do not want them! It is just a notification, log into the site and reply from there.

    b) To delete old conversations use the ‘Leave conversation’ option. This is just delete by another name.

    No, but a $300 DSP box probably can.

    +1 works great for me.

    If your speakers are active and you can time align drivers, then possibly $300 can do it to a point with lots of measurements and manual configuration. You'll only get a four channel solution from MiniDSP for that money however.

    Did it end up at £780 inc all import costs?

    Haven't had the invoice from customs yet, used my company to clear it so didn't have to pay up front.

    It was £650 so I'm expecting 20% VAT to go on top as there's no duty on electronic recording devices which this is classed as.

    The 22D is a digital only device which has switching regulators in the power supply path. Without any analogue circuitry to worry about, its highly remote a battery or linear PSU will make any difference, unless the stock SMPS is affecting other kit in your system.

    I just use the supplied wall wart on mine but in the interests of open mindedness and curiosity, I've just tried it with a Teddy Pardo linear PSU and can't detect any difference. Then again, it was sighted and my expectation bias works the other way round these days ;)

    Then that has an ADC and DAC, quite different to the product the OP purchased.

    It looks like I need to give Dirac a try one more time.Two times I tried it with the recommended curve and somehow it sounded strange and different to me, so I simply turned it off without too much messing with it.

    Have no idea what "numerically blameless" is but you are over analysing this.

    I tried it with the filter active and then switched off, for me it sounded better with the filter on.

    Job done.

    Wouldn't be the first time!

    I used to be a raging subjectivist for years. Then years of being a raging objectivist. Since I started my latest phase of over-analyzing and being OTT with matters hi-fi a few years ago (semi-objectivist, semi-subjectivist, or schizophrenic) I've achieved much better sound - maybe it's not so bad.
  15. SteveS1

    SteveS1 I heard that, pardon?

    Absolutely. Care is needed with getting the measurements right but I've yet to hear 'no filter' perform better than a filter in any of about seven or eight rooms I've tried it in. Being a bit OCD, I made three sets of measurements for my own room and went for the one I preferred although they were very close and all were much better than 'no filter'.

    Interestingly I have not been able to improve on the default curve although some report fine tuning to be beneficial. I lost interest in fiddling because I was enjoying it and no longer distracted by obvious room effects.
