    So that means a Multibit Bifrost would be superior to the DS2 Ultra?

    And then its kinda like Head Box DS2 B vs Ragnarok :p
  2. Left Channel
    If your ears find the multibit superior. Everyone's ears are different. I'm all non-multibit Modi and Magni here now, plus some of the warmer NuPrime products.

    Kinda sorta. More like Head Box DS2 B + Amp Box DS2 vs. the Ragnarok headphone/speaker amp.

    Not having heard them I don't know what to tell you, and I find the AKM chip in the DS2 Ultra very intruiging. But in general German and Austrian audio equipment is cooler and more resolving, French warmer and more forgiving, and American warm but loud and powerful. Or so a Taiwanese product manager once posted somewhere. He also said Chinese designs are warmer, Japanese more neutral/cool. But there are always exceptions.

    That is a great synopsis @Left Channel. I'm not really sure what kind of secret sauce Happens between the bimby and Jotunheim. But it sounds nothing like any of the previous DACs I had. It is A mesmerizing combination paired with a Planar Magnetic like the Hifiman HE560v2. So, thought it would be an interesting experiment to pair Pro-ject Prebox S2 Digital with the rest of my gear. I may just pick one up and document my findings.

    Looking forward to hearing your report! The Pro-Ject really is a different animal, not only in sound but also all the additional and highly un-Schitty tech: remote control, information display, filters, and support for DSD, MQA, and ultra-high PCM resolutions. If you do pick one up, see the summary of helpful hints in the Google Doc maintained by @Mark Dirac.

    Alright, so I just unboxed the S2 and hooked it up... This DAC is comically small in comparison to the scale of pictures online. Installing the drivers and I will test with the Schiit Jotunheim Amp and Hifiman Ananda's.

    :) Too bad you didn't see my photo! Here it is next to a Magni and Modi. Looking forward to your impressions.

    Do you actually hear a noticeable sound improvement when using the power supply unit that comes with the S2 versus USB power alone?
  9. Left Channel
    Yes, I do hear an improvement! I also tried replacing that PSU with a linear PSU as recommended by the designer of this product, but heard no further improvement even though many others do. That may be because (a) I used a cheap linear wall wart or (b) the power in my recently constructed home is much cleaner than most.

    I'm not sure if this question has been asked so I'll post it. With USB-C connections becoming more popular, will/does the S2D support USB-C connection?
  11. Left Channel
    To connect my phone to the S2D, I used a USB-C to USB-A adapter, then my usual USB A to B cable from there to the S2D. So in that sense the S2D already supports a USB-C connection.

    I don't know if Pro-Ject will introduce future models of this or any DAC with a USB-C jack instead of USB-B. USB-C is more common in fully portable devices.

    Having said that, I should point out that the new Schiit Modi 3, though a desktop device, now sports a USB-C input/power jack.

    Alright, So after a partial day of testing The S2/ Jotunheim Amp & Bimby/ Jotunheim Amp Stack combinations with the Hifiman Ananda... I can say the S2 Digital can hold its own against the Schiit Bifrost Multibit. The Bimby has a slight edge on sound stage and detail retrieval. Still testing with a variety of familiar songs across several genres. I like what I'm hearing so far. The only issue I encountered was the music stopping when I played MP3 or FLAC files from Windows Media Player. I believe someone mentioned a similar issue earlier in this thread. Has this issue been resolved. If so what was the remediation procedure?
  14. Tex Irie
    Also, I didn't reboot after installing my S2 Digital Drivers immediately. I encountered some difficulty rebooting and unplugged the USB cables I added recently. The S2 Digital was the culprit.

    I'm sure, I resolved my own issue by doing this. Brain burn in is real.. This little box is impressive when paired with the Jotunheim and a Planar Magnetic Headphone. Now to test the Optical input with my TV and gaming console.
