    External DACs

    It is very reasonable to assume that you'll get a better sound quality from
    the SB with a stand alone DAC. There are a couple of recent threads it may
    be worth you reading: "[OT] Audiophiles: Can the audio reproduction of
    theCDbeequalled or bettered?" and Squeezebox SP-DIF parameters.
    The general consensus seems to be that there is very little reason that you
    should not get very good quality reproduction indeed from a Squeezebox as
    long as:

    * You rip your Flacs correctly (using something like Exact Audio copy)
    * You use an external DAC. A couple of people in these discussions have been
    talking about adding quite expensive DACs to their SBs ($1000+!).

    I bought an Arcam Delta Black Box (over ten years old) via eBay for just
    less than ú100 (UK sterling) to see if it would improve the sound of the SB.
    It was ú100 very well spent. The sound quality has measurably improved and
    is much nearer to that obtained from my Naim CDX than it is to the SB
    analogue-outs. In addition the volume level, which was always frustratingly
    low from the analogue-outs is now on a par with that of all my other
    peripherals.
    I am hoping to borrow a good quality DAC soon to see if it worth me buying a
    better one than the Arcam, with the eventual aim of getting rid of the CDX
    all together. I'm pretty optimistic that this is a realistic idea.

    There are quite a few interesting DACs on eBay UK at this moment, including
    an Arcam Black Box and a Meridian 203, both of which should go for a little
    over ú100. Or, if you fancy something a bit classier:

    2 x Meridian 566
    2 x Tag McLaren Dac 20
    PINK TRIANGLE DaCAPO
    MUSE MODEL 2

    or, my personal favourite...
    Audio Note DAC4 (1x valve output) which is on "Buy Now" for a mere
    ú2,250.00!! :-)

    going on a tangent here, this always confuses me when you bring it up. I do use
    my SB with didgital out to my Yamaha RX595 (relatively cheap tuner/amp/dac), but
    when I had it hooked up using analog cables, I could still rattle the neighbours
    out of bed if I wanted to. Granted, its a shared wall, but I'm just not
    understanding how you end up with 'frustratingly low' outputs. In fact, my
    second SB using optical needs to be turned down from when I'm using my dvd
    player or I would again be waking neighbours. Last time I used analog was before
    the 'fixed digital output' settigs came into effect. Maybe that has some effect
    on the analog outputs.

    it is also my experience that the analog outs on the SB have a rather
    low level.

    with the SB volume level set to max, i'd expect these outputs to be
    pushing a similar voltage to a consumer level CDP. if this were the
    case, i could play back the same material via CDP or SB and A/B the
    inputs and have the overall system output be fairly equivalent.

    as it stands, i have to really crank up the gain (volume knob) on my
    preamp when switching to SB from CDP. it's not a huge deal, as my
    system has more than enough overall gain to get to the desired volume
    level, but i am also amplifying any noise on the line, and run the risk
    of not remembering to lower the levels when i switch back to CDP.

    The levels can go a little higher, but you'd be surprised how many
    people report clipping issues at their receiver if we go higher....

    interesting. and a totally reasonable argument for leaving them the way
    they are.

    or we could all chip in and buy a bag of resistor plugs for the clipped

    anyway, more of an observation than a problem. and i hope to make it
    irrelevant soon by picking up an external DAC.

    thanks sean.
