    Phantoms !

    Thanks George,

    maybe I'll see if I can get the Elgin's back for you

    I do find the coax sounds better ,especially over the distance I'm running.

    I tried with out the enhancer. I prefer the sound with it . It seems to open things up a bit.

    I have a problem with the cd in the iMac. It wont play or even recognise a cd.

    It plays DVD fine ,but not bloody cd's I have checked everything-got any ideas?

    I cant find audio midi set up either. Spotlight cant find it . It should be in applications , right ?

    In Leopard -
    Go to (system) Preferences
    CDs & DVDs
    "When you insert a music CD, (select) Open iTunes"
    (or select "Run other application" if you use something else)

    or, is it not Leopard?

    Go to Applications> Utilities>AudioMidi setup.app
    Assuming u have latest version of iTunes and your DEQX is capable of 24/96, set Audio Output to 96000,0Hz and 2ch-24bit. iTunes must be launched AFTER the sample rate is set in AudioMIDI.
    That way u tell CoreAudio to send 24/96 streams to the 24/96 (?) dacs of DEQX. Your CD's ripped files are "only" 16/44,1 so iTunes will upsample everything to 24/96. (Latest iTunes upsampling algorithms are pretty good!)
    You can always set it back to 16/44.1 if you don't like the sound, and let your DEQX handle the 16/44.1 stream. (remember to always quit iTunes before changing settings to AudioMidi)
    If you have purchased (or u've ripped) 24/96 music, u must set AudioMidi to 24/96, else iTunes will downsample to 16/44.1...(u don't want this)

    For CD playback, do what hjames suggested. Or go to iTunes>preferences>Advanced>Importing and select from the "On CD Insert" popup menu.

    important!... Make sure u always keep iTunes volume to maximum.

    Hope these will help

    One more thing! If u prefer the "Enhancer On" sound, try this, just for fun! With equalizer, make a new preset with preamp gain to -12db and move all sliders to +12db.

    Heather, George,
    So, I tried it . Distortion galore. I've gone back to your original suggested set up .

    I still cant find the midi set up Do I have to reboot with the Leopard install disk or can I just down load it from somewhere. Can I email to myself from my macbook (leopard)

    The cd just wont work . It has to be a setting somewhere ! Apple want $ 400 to replace the cd drive

    no ( zero ) reason to upsample 24/96 before DEQX.

    1. Either get a real soundcard ( Lynx , RME) - AES / EBU output
    2. high quality (megabucks) transport - CD or hdd based - AES / EBU output
    3. middle price range transport - slimdevices or Wadia Ipod dock
    Spdif output.


    Spdif sux.

    roundup:

    middle price range : slimdevices squeezebox vs. wadia ipood dock (1-0) (K.O.)
    megabucks range: slimdevices Transporter™ vs. regular cd transport (1-0)(K.O.)

    I would exclude macintosh vs pc cause thats the boutique question, I would not use either for serious listening, unless you access it from another room , terminal style , isolated AES / EBU or async USB (rare bird and most of USB cables suck )

    Spdif should be used with BNC cable.

    DAC: there are so many components we have at least a year ahead. BTW it goin to have AES/ EBU , async USB and DSP too. No spdif this time.

    Now I see Ian already mentioned slimdevices , Cheers!!

    Rich, macintosh spdif out sucks because it has an embedded clock that is corrupted by the DC DC converters + switching power supply and this manifests itself as phase noise, it is sent thru the spdif cable into the deqx as well.
    Im not sure distortion is linked to this behavior. If you not experienced with MSB dac then you sohuld try the squeezebox with deqx for real, even better rent a Transporter, preconfigured to a degree.

    Hmmm..

    Ok. seems we have two issues. 1. Audio setup and 2. Audio CDs playback.
    1. If Utilities Folder is missing from Applications, afraid u have to do a clean install from Mac OS X install Disc.
    2. Don't even think paying $400 for the drive. (Is it combo or superdrive?)
    First, see if there are any firmware updates available from Software update. Check if this happens to ALL audio CDs (bought, or burned) If this happens on bought cds, check if there is any kind of copy protection label on CD covers.
    But I assume u have already checked these.
    Last.. Create another user account and see if u have the same problem.

    Then... u have to assume u have a drive failure... (quite strange though, as it reads + plays DVD discs! ) and u will replace it... easy!!!

    apogee is way overpriced and bad as example because both of these are either usb or firewire.
