    Hmmm...that's odd, and in jRiver/Foobar you can perfectly play DSD256 natively (Bit-streaming to DSD enabled)?

    I wonder if anyone else can test this driver, I'll probably give it a try myself to a different computer. Thanks!

    I've tried too. Doesn't see my Play.
    Might be different firmware or board revision ?

    It depend of the slew rate. Higher the slew rate, more prone to oscillation.
    For audio it's safe to have OP'AMP's with a slew rate between 10 and 30V/µs in I/V. For buffer/LPF you can go even lower - 4-30V/µs. However I found that depending on DAC and schematics, having a slower than 16V/µs in I/V may have some issues with instrument separation on faster passages with lots of instruments - like symphonic orchestra.
    Having a slew rate over 30V/µs is useless and may not end well.

    I got the first part of my review done. I will likely revisit it with the Burson V6 Opamps and a couple others I have to look at customization a bit. But for now, here is my review of the Swing as it comes out of the box.


    I'll get it posted here too shortly.

    My Swing came today. Here are some inside pictures.

    I have had the Swing a few days now to let it break in. At the recommendation of Alex at Burson Audio, I set the Swing's output to DAC. With that setting, the output uses the RCAs on the outside which sets the Swing to a fixed output. The default output setting uses the Swing as a preamp making it variable output, which are the inside RCAs. My Swing has the mixed Vivids and Classics like the Playmate Everest only with the mixed duals and singles since it does not have the headphone amplifier.

    One other setting I changed at Alex's suggestion was turning the Emphasis off. I did this at the same time as I switched to using the DAC direct. All I can say is I did not want to shut things off tonight.

    The Swing is feeding the Fun with two V5i-S using the included RCA cables. The Swing is being fed by Roon using a LH Labs 1G USB type B cable. The Fun is feeding my HE-400i, which are using a 4-meter MIT Vero Full headphone cable.

    I must say, while I expected it to sound good, tonight it is sounding well beyond my expectations. The decay in the notes is just so natural with the instruments and vocals placed where I can see them when I close my eyes. The depth of the stage is a little on the shallower side with more to the front presentation. Roon Radio was providing the music selection based on Natalie Merchant.

    Really love the V6 Vivids in the Swing using the DAC output. Seems to be a bit more dynamic than the default or the V6 Classics.

    I'll wait for cv2+ dac vs swing dac ! :D

    There is a 48h Burson offer:
    Similar with the Play offer about a month ago.
    I think they want to get rid of V5 stock.

    Very good opamps, I remember when I placed my V5 inside the Objective2, I thought the background will increase for sure, but it was still dead silent. I totally recommend the SWING with V5, a very good offer indeed.

    Does the screen turn off after a while or is it always on? I’ll be worried of burning the screen if it’s always on.
  11. Wiljen
    its always on. I turn mine off when not in use to prevent burn-in.

    Interested in this DAC. How does switching the inputs work? Couldn't find any info on it. I assume the knob is volume since it's also a preamp. Does it push in to switch inputs? Looks like the remote only has buttons for volume up, down and mute? I have Gilmore Lite Mk2 coming and wanted something that matches its size and have phone/tablet connection and this fits the bill.

    On the right of the knob it has a small button with "menu" function. The knob rotation is doing the menu scroll. Pushing the knob is "mute" in preamp mode.
  14. i20bot
    Ah ok, thanks. I thought that was a button but then thought it might have been the IR for the remote too lol.
