    Korg MOBILE 1BIT USB-DAC DS-DAC-100m

    I still have my unit, but don't use it that often. The software has been updated a couple of times, and it's far more reliable now, and it also seems to work fine under Yosemite on the Mac.   One problem for me at least, is that 98 percent of my files are FLAC, and while I have some DSD files...

    Schiit Happened: The Story of the World's Most Improbable Start-Up

    Jason,   I think your observations on trade shows is spot on. In a couple of weeks I'll be attending some disparate shows, CEA Line Week in NY, Pepcom in NY, and ISTE in Philadelphia.    Interesting mix, as it's not unusual at the CEA show to see a booth from Sony featuring their cameras...

    OPPO HA-2 Portable Headphone Amplifier/DAC Discussion Thread

      Hi, not off-topic at all. You have to feed the DAC!   The short answer is yes. The Seagate Wireless Plus is one example (In its third revision) of a large HD (1TB in my case) with a built-in wifi hotspot. You can sync any device with wifi to it, and stream whatever files are on it, so it...

    OPPO HA-2 Portable Headphone Amplifier/DAC Discussion Thread

    Hi!   I've been using the PM-3's and the HA-2 for about two weeks now.  Last week I attended a conference in New Orleans, and thought it would be an ideal way to test the new gear on the road, in planes, etc.   First thoughts are that the combination of the HA-2 and PM-3s are a dream combo...

    OPPO HA-2 Portable Headphone Amplifier/DAC Discussion Thread

    I have spent a week with the HA-2, driving a variety of headphones, from Audio-Technica (open and closed back models), vintage Sony, and Oppo's PM-1 and PM-2 headphones.   The fast charge is indeed fast, but the unit kept charged when I used it as my DAC/Amp with my MacPro and MacBook Pro. The...

    OPPO HA-2 Portable Headphone Amplifier/DAC Discussion Thread

    We had the pleasure of hearing the HA-2 during CES in January, and both of us thought it a superb unit. The leather covering reminds me of a vintage Jaguar, feels great, isn't flashy, but secure and luxurious. The controls were solid and well-machined, and we listened to the upcoming PM-3's with...

    Sony DR-Z6 (Vintage)

    Well, a good question. The Sony's are much brighter, more pin-pointing in terms of high-end response and as a result the lower end is more open, but they are also nowhere as comfortable, have a brighter overall sound then the Oppo PM-1, and are less warm and enveloping. The Sony's seem more...

    Sony DR-Z6 (Vintage)

    Hi,   When I first joined Head-Fi it was in search of information about my DR-Z6 headphones, and I've really enjoyed learning about other folks experiences.    Recently we published a review of the new Oppo HA-1 Headphone Amplifier/DAC, and for kicks I pulled my DR-Z6's out and tried them...

    Has anyone heard anything about the Oppo HA-1 balanced headphone amp/DAC?

    I've not heard the NAIM so can't compare. What was a revelation is that I have some headphones that are high-end, but to whom I've never really warmed up to. I think the old sense that you should love XXX due to the price, reputation, etc. But I could never put my finger on the cause. I kept...

    Has anyone heard anything about the Oppo HA-1 balanced headphone amp/DAC?

    Hello,   Having lived with the HA-1 for several weeks now I can state that I've never heard a better headphone amp/DAC. Coupled with the PM-1 the experience is sublime, easy-to-use, and aesthetically pleasing.   I have the silver model, which is lovely and understated design wise. I've also...

    Has anyone heard anything about the Oppo HA-1 balanced headphone amp/DAC?

    Hi Doug D and EraserXIV,    So, the HA-1 does have a USB input in fact two of them, one on the front panel designed only for input from an iOS device, and it will take over the DAC duties, so pretty neat. But, that is all you can use the port for.   The rear port is only for input from a...

    Has anyone heard anything about the Oppo HA-1 balanced headphone amp/DAC?

    Hi, I think that is a great question. The BDP-105 headphone amp is seen by some as a "by the way" aspect of the 105, but I think that is incorrect. When I reviewed the 105 I asked Oppo this very question, and the answer was that the amp was carefully designed, and had the advantage of running...

    Oppo PM-1 Planar Magnetic Headphone Impressions Thread

    Hi Q Mass,   I've been using the calfskin pads, which are perforated, and have had no trace or sense of overheating. Once I feel I know the sound with these pads, I'm going to switch to the velour to see how they affect the fit and sound.   I remember my first pair of Koss 4AA's, whose vinyl...

    Oppo PM-1 Planar Magnetic Headphone Impressions Thread

    Hi achristilaw, thanks for your post.    I came to reviewing products the old fashioned way, starting in college on our 10 watt radio transmitter, and later on larger broadcast stations, but it was never about the vendors, it was just discussion of products, technology, and value. And...

    Korg MOBILE 1BIT USB-DAC DS-DAC-100m

    Hello,   Yes, I've been working with the DAC-100m since CES. Actually I should amend that. I've had the hardware since CES, but the drivers arrived later.    It is well built, and once I managed to get the system to recognize the hardware, which required a couple of install and uninstall...

    Oppo PM-1 Planar Magnetic Headphone Impressions Thread

    Hi!   I too wear glasses, but haven't had a fit issue from them. I think I have a bit of a narrow head though, since the Audio-Technica Wing system doesn't always hold their headphones on my head the way I liked. The solution was a rubber band between the wings, so for me the PM-1's are really...

    Oppo PM-1 Planar Magnetic Headphone Impressions Thread

    Having lived with the PM-1's for a few weeks now, one thing I can say is that they are light on the head. With some of my better headphones I often have this little twinge of "ok, time for serious listening" thought that goes through me when I'm just about to put them on. Ok.. I'll admit, it...

    Has anyone heard anything about the Oppo HA-1 balanced headphone amp/DAC?

    I should add that because I'm working with a pre-production sample, I'm not sure when the official public ship date will be. There will probably be some options that will change with shipping units around the guide, included accessories, etc.    In many ways this is a get-out-of-the-way...

    Has anyone heard anything about the Oppo HA-1 balanced headphone amp/DAC?

    Hello!   So, my sons (they are home for Spring  Break) called last week to say this large box from Oppo arrived.  As soon as I got home the HA-1 pre-production review sample and headphone stand were indeed waiting for me. The packaging is what you might expect from Oppo, with careful packing...

    Hi,   This is what I wrote in response to a question from Headphoner on the Oppo HA-1 thread about the sound of the PM-1. Guess I should stick to this one.   Anyway...   Harris   ------------   Hello Headphoner!   So, I'd like to clear up something that is bothering me. A few folks...

    Has anyone heard anything about the Oppo HA-1 balanced headphone amp/DAC?

    Hello Headphoner!   So, I'd like to clear up something that is bothering me. A few folks on these threads said the box the Oppo's come in is plastic, and it is not. It is wood veneer, over MDF, then finished to a high degree.   I know it wasn't your question, but I thought I'd set the record...

    Has anyone heard anything about the Oppo HA-1 balanced headphone amp/DAC?

    Hi Ben_R,   Reviewers never give out their trade secrets!   Actually I have been reviewing products for an awfully long time (30 years), and reviewing Oppo products since their early days.    I find it amazing to see stratospherically priced systems where every component is outrageously...

    Has anyone heard anything about the Oppo HA-1 balanced headphone amp/DAC?

    Hi,   The TM-1's that I tested terminated in a 1/4 plug, and there was a step down adapter for use with a mini-jack, not sure of the manufacturer of the step-down cable.    We did joke about using the HA-1 with a huge battery as a carry-on for in-flight use! Hey, let me get rid of that dinky...
