    Thanks John. I'll have a go at following your instructions. Just ordered the Paul Hynes supply as well. Going to get a NAS next, any suggestions as to which one to get?

    Hi Stephen, I have ordered the Paul Hynes supply, will bear that in mind that the router can be upgraded too but I intend to hardwire the NAS as and when I get one.

    Well chaps, I've tried messing with these filter setting before and struggled to hear much difference. I've just had another play and really cannot hear any difference.

    Are we really sure these settings have an effect when the DAC is set to "Resampler: Off"?
    Maybe it's because I have an effective analogue low pass filter directly after the DAC?

    Just in case there are any accusations of deaflugs etc. - I can hear significant changes to the sound with even tiny mods to the 5V PS feeding the Pi & DAC.

    Maybe it will all be moot when the new Moode 4.4.23-sc1 super kernel comes out???

    Well I did some more dabling with the Pi and IQAudio setup and maybe I slighlty prefer the "Low latency IIR with de-emphasis". Anyway I left it there.

    I also tried upsampling to 48 & 96KHz, the logic here being that the Pi clock is a multiple of these frequencies. The sound was worse than with no upsampling.
    Then I tried the software volume control. Rubbish! I only tried this because someone on DIYAUDIO said it was better.
    Finally I tried running the combo from batteries (LiIon at 8.4V into my LT1963 reg). Preferred the transformer front end.

    So, pretty much back to square 1!

    Might press the button on a KALI and Piano2.1 or might try powering the IQAudio DAC separately.

    Allo Audio has a re-clocker called Kali that can (apparently) be used with the Audiophonics DAC's. There is a thread here discussing it. Looks like a nice upgrade to existing compatible Pi DAC's

    Why such long leads on the Charcroft resistors? Seems counter productive. I would snip the leads and bend in to keep things short, rather than putting two antennae in a box.

    Default Paul Hynes power supply.

    Just received the Paul Hynes PS I ordered a little while ago. Sat there the whole evening upon firing it up for the first time listening to all the tracks I have on a USB stick - a nice mixture of ripped CDs and paid for high-res FLAC files.
    First impressions were very favourable - a huge improvement in the bass, in fact on certain tracks the bass was almost too much - down to the recording I'm sure. Separator by Radiohead sounded the best I've ever heard, Colin Greenwood's playing more noticeable and musical than previous (ripped CD ).
    Joni Mitchell - Court and Spark - 24 bit FLAC, an album I know very well was again the best I've ever heard it, lyrics were definitely clearer and the musicians playing became more defined and separated yet more closely intertwined as a band playing together. As others have commented, spending £500 plus on a PS for a £90 DAC does seem a bit crazy but I think this is more to do with the superb value the Pi / IQAudio DAC represents.
    Matthew.
