    I think most people will want to keep soren's stock filters because of the dsd support, even if you don't have much dsd in your library. One cool thing alvin did is to include the serial port to make it easier for people to install filters/update firmware. Although using hyperterminal type communication program with command line commands is going to scare off some people from trying to do that :p I wish Paul would update his filters or publish like.. a tentative update schedule or let us know he didn't abandon them

    My Vinshine r2r arrived and is everything I was hoping.. has a distinct sound from delta sigma.. by memory is better than my vi dac infinity solid state. The case is pretty impressive with nice thick panels, thick and heavy enough that gluing dynamat to the insides isn't necessary :p So far I've only used it with my speaker setup, still have to test the headphone amp, which is a pretty important part of the product.

    Hrodulf do you remember if this dac does dsd by converting it to pcm? I forget how it does it. Or is it true dsd output. If so, this and the holo dac are the only affordable r2r that do dsd

    Sorry -- I don't have time to go thru this thread or the super-confusing and fine-print-free VinshineAudio web site.

    Does the Vinshine DAC allow user to easily select between digital filters (or NOS)?
    Many software DIY digital filters seem to have been created (per DIYA threads). Which filters (if any) does the Sokris in the Vinshine offer?

    It comes with the four stock filters from soren, the creator. You have to use a usb to serial cable to change filters, which is annoying but on the plus side you can also upload new filters that way, there's a couple of filter packs from diyaudio you can install. One of the stock and party pack filters are NOS

    Very tempting now that the Soekris 1101 have a HUGE 61% discount.

    http://soekris.eu/shop/dac_modules_consumer_line_en/

    Got a LH Labs Revive to power it up. With an equally small/nice headphone amp, it would be a very interesting transportable setup.

    However have fully a tricked LH Labs Wave coming so ever slowly. And have already a desktop DAC. Hmmm...what shall I do.

    Wow I wonder why the discount. It must not be selling.. reviews didn't seem that good. I still really love my vinshine dac powered by soekris...

    Reliance on USB power means that you'll get a large variety of impressions depending on "transport" quality. I wouldn't buy a transportable unit for 500EUR which only works well with USB decrapifiers and dedicated power supplies.

    At this price it is really tempting... As a desktop DAC via fixed RCA only, not planning to use the headphones out. With Wyrd or another cheap USB decrappifier as an option, this might well do the (r2r) trick.

    That pricing looks pretty on-point. I'm excited to hear if they deliver sound wise.

    I do not understand why Soekris insists on using output buffering.
    At least another set of RCA-s to tap off the pure juice wouldn't have been much to ask.
    It would be equivalent of Shiit to only offer summed output of it's circlotron designs.
    I wager the sonic impact will be worse in case of the Soekris buffers.

    For most downstream it doesn't even need any buffering. Most pre-s are barely lower output res, only real issue is low-ish output level.
    It even drives headphones to moderate levels without any damage to itself.

    I don't see too much of an issue with buffered outputs on their finished products. Most manufacturers, including Schiit, have buffered DAC outputs.

    That being said Soekris has DIY and OEM boards with unbuffered output. You need to case it yourself though.

    I'm too pedestrian to be able to estimate the possible shortcomings of Soekris' output buffering, but at this price point if they deliver decent quality the DAC1541 is right up my alley for a desktop dac/amp/pre.

    It would also be a decent shot across the bow of AGD, or a death blow if the singularity 19 is representative of what they are producing in R2R for the future.

    My DAM1021 didn't require a buffer per se and as I understood direct ladder output was pretty capable of driving stuff. I recon that some folks might want a hotter output, so that's where it might make sense. In the case of DAM1021 the buffered outputs did phase splitting and could drive headphones, but did sound worse than the SE outputs.

    Welcome Soekris!

    HDMI for I2S (instead of BNC), Native DSD support, and Crystal Femto Clocks would be nice additions on DAC1541.

    Don't you have to convert DSD to PCM internally to output on on a multibit DAC, anyway? I thought it was only DS that actually uses 1-bit pulses to output?

    I always regarded claims of DSD support on any sort of multibit DAC as just as suspect as the provenance of a lot of expensive DSD files.
