    Now that 2016 is gone, in the rearview mirror, forever to be forgotten, I look back on some highlights.......just kidding.

    Other than the release of the microRendu and the Holo Spring dac I found little to be excited about in 2016. It sucked! And through it I had my worst health crises (I am fine now, thanks for asking ). But one audio company, a small family-owned business in Sparks, Nevada, kept me toe-tapping in my music, come hell or high water. And that company I discovered in 2015. In fact, I so owe it to the readers of Computer Audiophile to become aware of Shane Duffy's wonderful little company that I thought I would shout it from the hills (no hills here in Cleveland, but just go along anyway).

    PERLA AUDIO! Yes, Perla Audio, the little audio enterprise that had the cojones to introduce new amplifiers and preamps (and a DAC and some wild new speakers) into a very crowded and mature industry segment.

    Perla's ideas started in 2010 when Shane and his family decided to mortgage out the nestegg due to his zeal and commitment that a new set of speakers would impress the audio community. But he needed more technical help and in came his technical partner-to-be, Ronald van Robinson, a 30 year veteran in the industry. Perla Audio was born sometime in 2012, and their first products (while continuing to work on speakers) included an integrated amp called the Signature 50, a dual mono design which, among other features, had no coupling capacitors in the path. It wasn't long that this product got the reviews and awards it was destined for, including my buddy Terry London's wonderful review in HomeTheaterReview.com (Best of 2015 award) and Dick Olsher's large kudos in Absolute Sound ( 2015 Editor's Choice award). ...

    Best Of Both Worlds? Best of Neither?

    The Holo Audio Spring Level 3 Kitsune Tuned Edition R2R PCM/DSD DAC

    The world of digital audio is often a confusing one to the prospective buyer. How does one differentiate between technical jargon and marketing terminology, especially within an industry segment that is changing rapidly and offering supposedly the same sample and bit rate playback from $199 to $99k? Does one need to buy a PCM dac and convert any good DSD-based music to it? Conversely, buy a DSD-rich system and then upsample to that system's DSD sweetspot? Which upsampler? Own two dacs?? Yikes.

    Nowadays there is a sub-sub segment of this confusing DAC market that seems to be offering two dacs in one, a PCM side and a DSD side. Keeps cold things cold and hot things hot...how does it know?

    This review is not hugely technical (duh, mine never are) for many, many reasons, not the least of which is due to my brain stem and Catholic school math and science burnout. When I got to a Marianist university I discovered pot, sex and philosophy (mostly in that order). I realized that technical things need to be explained via the soul, not the brain, in order to make sense for me. It's really well-justified laziness, but I had finally found my comfortable skin.....if I don't need to know what ketones are used for, I don't need to know ketones! Period. B.S in English and Journalism, career in software sales/management. Dumb down tech jargon to make sense to a burned out elitist. Enough about me. ...

    The exaSound Playpoint Stereo/Multichannel Streamer (Jack of All Trades, Master of at Least Four!)

    When the computer audiophile world began to embrace the onset of ethernet-based music streamers, it was slowly becoming clear that not all DACs could seamlessly take part in this (general use) computer-less setup. As DAC manufacturers pushed for better and better integration with computers, some of them went as far as creating specific drivers to take advantage of direct handshaking with such higher resolution formats as raw DSD (as opposed to getting one's DSD packed in a PCM carrier, aka DoP). This integration often had sonic payoffs, but made plug-n-play Linux UPnP streamers, looking for common drivers in the USB Audio Class 2 category (aka UAC2) too pedestrian to be able to talk to these DACs. And although some of this has changed over the past couple of years (Linux code lines now embrace some native DAC drivers of various manufacturers, above and beyond UAC2) some DACs still would rather interface more closely with proprietary drivers. One such DAC manufacturer that has espoused this direct driver philosophy is exaSound. ...

    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)? ...
