    Nice looking turned wood - what kind of finish do you have planned?
    What drivers are you going to use with them?
    Are you going to put them in your Altec Cabinets?
    Or on top like I did with my walnut smith horns?

    Broke down and bought a Micromega MyDAC - the big gain is it has 3 switchable ins - USB, Coaxial and the Toslink/Optical.
    Interesting that is not chinese but French designed and manufactured.
    My main source for that system is optical out of the Airport Express/iTunes,
    but its nice that I can also pull coaxial out of the old Oppo DV981HD.
    Just arrived this morning and I just got it into place - its a tiny thing -
    about 5" x 5" by 1.25 or so - power supply is internal - so no wallwart!

    Sounds quite nice from what we can hear - but reviewers for a lot of DACs say they get better after running in for a hundred hours or so,
    so I'll let it cook before I do any serious review and make any comments.
    Has a front panel switch for the sources - kind of roll the knurled edge under your thumb to select
    from OFF through the 3 sources - USB, COAX, OPTICAL.
    So far, it IS an improvement over the internal DAC of the OPPO and the Airport Express unit ...
    but as I said, I'll wait for burn in before giving any longer comments.

    I'm inclined to leave the 1% out of this, so let's assume it's good for merely 99% of all people. I'll probably pick one up and try it.

    Has anyone tried the new Oppo BDP-105? Too bad the DAC in that thing isn't available separately?

    Try this:

    Queue up a CD in your Oppo and the same tune via the Aiport/Optical and compare optical vs. copper. With my Bryston DAC I found copper coax sounded noticeably superior to the optical.

    Hey Heather,

    Just reading up on your new toy, I see it's got Asynchronous USB. Everything I have read suggests that asynchronous provides the lowest jitter of all the connections, with the highest resolution 192/24.

    My MusicStreamerII is only USB, so if you get a chance to use the USB, I would be interested if there was much of a audible difference between USB and the others.

    With the Airport Express, my only digital choice is Optical.
    I'm using a plastic optical cable I got from Seawolf's Cables sale last year.
    Of course, this might be the time to buy a nice optical cable,
    but I do consider that the Airport Express itself is only $99.
    Anyway, since optical on the DAC is already in use,
    with the OPPO I am using copper Coax, and its nice.

    I'll take a demo of a track over Wifi/optical vs one in the Oppo/Coax and let you know.

    Maybe once it "burns in" for a bit I could try the OPPO optical feed, just to know,
    but since I'll be using Coaxial from the Oppo, there is no urgency.

    I don't have any USB sources near the rack - so nothing to test,
    [my macPro is a half flight up in the office and a devil to move].

    Anyway, the alternative choice was the Schiit Bifrost -
    but they were back ordered so I couldn't get one now.
    Plus, if I ever DID want USB, thats an extra $100 option taking it to $450.

    I have yet to hear any reports from any reputable sources that there are any differences between optical cables.

    Please do the comparison and report back. I'm curious.

    Only the 20/20 ones are any good.

    Yet another change - I had tried a low-mid price piece - MyDAC, french made - was ok but since it did NOT best the $25 FIIO D3, MyDac wasn't to be my DAC, and back it went.

    Got an Audio Alchemy DAC-In-The-Box couple weeks ago - an older piece, used, for under $100 shipped. Has BurrBrown chips and a pleasant sound. Its a keeper.

    Then an AK member was closing out all his older Audio Alchemy gear and I got a DDE-3 DAC from him. Supposed to be a few step up from DITB, and decodes HDCD, which is a plus for running that Oppo DV981HD through it. The Oppo says it will decode HDCD itself, but I've always been suspicious, as it has no indicator lights or anything like that - best use of it for HDCD was paired with the late lamented Harman AVR 7300 top of the line and letting IT decode the HDCD.

    For the Oppo, if I use the Coaxial out, it bypasses OPPOs HDCD decoding, so owning a DAC that can do HDCD as well as the usual DAC duties is a real plus for me - I'd guesstimate I have at least 50 HDCD in the collection, probably more.

    I hooked the DDE3 up and have been playing a bit of music since it came - nothing too critical as my head is stuffy today - recovering from the flu that dragged into pneumonia. I'll do a thorough listen, if my head clears tomorrow or over the weekend.

    Nice looking unit - a pity they are Out Of Business ...

    Hey Heather,

    What kind of digital cable is that? Looks clear. Is it one of those oil filled cables?

    even a 40 year old recording of the Grateful Dead Live at RFK stadium in DC was incredible.
    Bass was tight and distinct - and had an impact - it was like everything had been slightly out of focus,
    then this DAC did a rack focus and all was crisped up! Had to pry ourselves away after an hour of OMG moments ...
    I think the next stage is to run the old OPPO 971HD I have in that system though it and see how it sounds with an updated DAC ...
    and if that is revealing as well, I'll replace that $20 demo DAC with a 2 input DAC for that system!

    Nothing fancy, just an optical cable I got when Seawolf bought out an interconnect shop a couple years ago.
    I believe the package said RCA - whatever that brand means these days.

    optical cable, huh. I wouldn't have guessed that. I figured it being clear to the outside would cause issues. But I guess not. But then again its probably not multimode fiber.

    Nope - its much different than optical fiber for networking or distribution use. Does quite well.
