    The exaSound e12: The little engine that could...change how we think of sub $2k DACs


    George Klissarov of exaSound had an idea that he could take his award-winning e22 stereo DSD DAC and create a lighter smaller (read: less expensive) version that lost none of the sound quality....none! The savings would be in case size, inputs and output parts, removal of the display and an ever so slightly less refined power filter. He told me about it over a year ago and I jumped at the opportunity to hear it. ...

    I was asked by the folks at NativeDSD.com to see if readers at ComputerAudiophile.com would be the right audience for testing the results of two different DSD AD converters, a unique experiment in recording music. My answer was a resounding yes; the DSD (and overall DA and AD converter) technology is nothing new to us here, and this would be a great and fun way to find out what our DSD-capable equipment (and our ears) are telling us about things like sweet spots within DACs, the importance of DSD bit rates, etc.

    The Question

    In the brave new world of High Resolution Music Downloads many music fans have asked a big question. Is there a difference in sound quality that comes from recordings made at different resolution levels and different Analog to Digital Converters (ADCs)? ...

    PS Audio DirectStream DAC, a chameleon in the high foothills, by Ted Brady

    This has been the hardest review ...

    As I sit here sideways at my keyboard, with my twice-daily ice wrap around my knee, elevated and precarious, I am reminded of my doctor's response when I asked him why this seemingly innocent outpatient knee 'scope is taking so damn long to heal (three and a half months of pt, etc). To paraphrase: "Even though we have been doing these for many years, hundreds of times each per year, the prognosis is always different. Everything matters! Age, location of tear/damage, predilection to fast healing, diet, exercise, etc etc. So, PLEASE, do not read about 3 week recoveries on the Internet and expect that to be the norm. It's not a new science, but it's full of variables. We took a lot of lateral meniscus out, for example."

    Well...this article is not about my knee pain. It's about my music pain! Not really, but it is about one aspect of our own science (hobby) that is filled with many variables, where "everything matters" (note: as much as I like that terse, succinct, accurate, frustrating mantra I have to give credit to our own CA contributor Barrows for truly inventing it as his own).

    So..what am I getting at? Computer audio is far enough along that many new hobbyists expect there to be some standards and feedback that can help reduce the almost infinite variables involved in making a good knowledgeable decision about a new music system based on computer playback. That would seem to be a fair expectation. So why aren't there more "fundamentals" or "dogmas" in computer audio after all this experiential data from many users. Why not? My opinion, alone, is this: few of us can experience removing enough of the largest variables in this hobby to discuss any semblance of "fundamentals", because those variables are

    1)
    our own room;
    2) our own hearing limitations;
    3) our own listening preferences;
    4) our system make-up as a whole (i.e cake recipe vs cake) and finally,
    5) the introduction of a new piece into those first four aspects.

    (Computer Audiophile Contributor Ted Brady completes his thorough review of the Chord Qute HD / EX with this final update. I don't think there is anyone in the industry with more insight and time spent with this DAC than Ted. His original review of the HD and two updates can be read HERE. Below is Ted's wrap up with incredibly high praise for the EX. - Editor)

    I have owned the Chord Qute EX (aka EX) now for a couple months (arrived Feb 10) and wanted to wrap up my feelings about this DAC; i.e what is different about it from the HD I reviewed above, and what additional information or impressions I have of the Qute DACs since last writing about them. ...

    Confessions of a DSD-Aholic, by Ted Brady

    One aspect of being able to have review/demo units on one’s system for review (thank you Chris) is that there comes a time when you need to send them back. And although I’ve demo’d dozens of DACs over the years I’ve never really experienced the angst that a return could bring on. Until now…

    I really miss the Chord QuteHD. There I said it; I was once a strong man of principle, and now reduced to a weak yearner of days gone by. In reality, I borrowed the Chord for WAY too long a period (as some of you who know me understand that this review is like 4 months late ☺) and I thank the NA distributor, Jay and Katherine Rein of Bluebird Music, for their patience…which ultimately I tested for too long of a period. I don’t blame them at all. ☺ But I do miss that thing.

    OK, so why did I have the Chord for so long, and what is it about the thing that I miss? Well, this story ultimately began when I first discovered the DSD format back in September of 2011. ...
