  1. Looks like Soran Kristensen has picked up his game also with a new flagship R2R DIY board that's not too expensive. http://www.soekris.dk/dam1941.html "It support up to 24 bit / 384 Khz PCM and DSD 256 input, with FPGA based reclocking and custom digital filters, < 0.3 ps jitter clock generator, with 27 bit resolution. Firmware can be upgraded though a standard serial interface." https://www.diyaudio.com/forums/vendor-s-bazaar/327381-dam1941-gen-discrete-2r-sign-magnitude-24-bit-384-khz-dac-module.html Cheers George

    Registered and got this block diagram with pinout out of them, but no data sheet or evaluation boards are available yet. Looks to have 4 x balanced outputs, it's a quad, and all are current outputs so you'll need your own I/V stages. Cheers George

    I know it's DS, that's why I said: "AKM seem to me to be the leader of the "non R2R" dac chip sound" Doesn't mean I like DS or "keen on it" as you say. But others are, that's why I posted it. It would be good to see you start a thread for a change, instead of just commenting on everyone else's all the time.

    Just like getting samples from TI or AD Daniel, I'm sure you know how to fill it in to make it look legit to them. Cheers George

    As tube preamps go, I'd go along with that. GLWTS very nice sounding tube pre. Cheers George
  14. AKM seem to me to be the leader of the "non R2R" dac chip sound, this new one is said to be very good, wonder if AKM do Eval Boards like AD and TI do. https://www.akm.com/akm/en/product/detail/0054/ Cheers George
  15. The PCM1704K ("K" stood for special selected) is "said" to be the last and best R2R made for audio, my Linn CD12 MkIII uses 4 of these K's in it. There are old R2R chips still being made like the Schiit Yaggy uses (Analog devices AD5791) but it wasn't designed for audio but said to be for a US missile guidance system or as it says on the data sheet high end aerospace instrumentation. https://www.analog.com/media/en/technical-documentation/data-sheets/ad5791.pdf Now it up to the discrete R2R designers Holo, Denafrips, Sokris, Total, ect, ect to get up to and maybe beat the PCM1704K, and if the Holo was any indication that I used, there already up there.
