    @raoultrifan can you add Fun to the comparsion as well?

    I can do that, of course. Meanwhile, I just finished my PLAYMATE vs. CV2+ test with "Head-Fi and HD Tracks" and a "Test CD Officiel for Bass". I'm unable to tell a difference with my Fostex T50RP-mk3 planars.

    Opamps from inside PLAYMATE were 2xJRC5532DD in I/V stage and 2xLM4652NA in voltage-gain.low-pass. Swapping for MUSES01 makes no difference; maybe I might need to try other headphones too, but one thing's for sure: when I swapped opamps in PLAY differences were quite there, but in PLAYMATE I can't hear anything (at least not in 30 minutes of A/B testing).

    I've used A/B test with perfect volume match.

    However, CV2+ has an advantage of a much lower THD+N and an incredible power reserve too (not mentioning the beautiful massive look & feel.
     
    escalibur and Baten like this.

    Do you have any explanation why would the Play be much more sensible to the op-amps rolling than the Playmate? Also have you tried to test it with the speakers? In my experience, listening through big speakers, gives much more soundstage and instruments separation differences, than listening through the headphones only.

    I just installed the V6 Classic on my PLAY Mate and found the instruments sounds a bit dryer than V6 Vivids Duals and Sparkos SS3602.

    It's most likely due to the internal power regulators, especially when speaking about PLAY V1.6. Also, PCB traces, star grounding and ground plane, but...of course EMI/RFI may influence the output sound in a small manner.

    I was able to A/B compare PLAY vs. CV2+ too, but with most music chosen on my T50RP-mk3 planar headphones it was almost impossible to sense any difference. Maybe I'll need re-test with different headphones (HE560 perhaps). However, with highly compressed music, at high recording level and low dynamic (e.g.: "Milk & Sugar Beach Sessions 2018"), PLAY seems to sound a bit fatiguing on the trebles, sort of a less separation between sounds and somehow more compressed and less clear. It's like music starts to get distorted somehow and some of the details starts to fade out a bit. CV2+ seems to drive a little bit more "effortless" such kind of music on T50RP-mk3 planars. For all these A/B tests I've used WASAPI and perfect volume match.

    L.E.: Tested PLAY was V2.2 and opamps used were JRC5532DD and 5534DD.

    Has anyone figured out how to get 32-bit audio options in Windows for the Burson Play? Because it is advertised as supporting 32-bit but it seems it only gives 16-bit and 24-bit options.

    Have you installed the Burson driver?

    For me that one defaults to 44.1 32-bit, in the driver toolbar it also defaults to 32-bit. Windows 10.

    I may be user an older version of the driver. Do you happen to know which one you're using? or have a link?

    Uninstall previous and install may 15 driver :)

    I thought v4.59 is for Playmate only. At least in my case PLAY and CV2 do not work with this driver, but v4.59 does.

    If I remember correctly, I only got 32-bit audio in Control Panel only when I used default Windows 10 XMOS drivers.

    However, getting it to play 32-bit audio will not improve audio quality, and I'm also not aware of any recording studio recording songs by default in 32-bit.

    What is really important is that PLAY is using internally native 32-bit processing to adjust the output volume through the rotary knob; this wouldn't be possible without a 32-bit DAC, unless adding additional active or passive components which usually contribute to increase the noise.

    Thanks for the reply. Which driver are you using for the PLAY?
