Denafrips Terminator R2R Multibit, ultimate pcm redbook converter??

You also need to mention the massive amount of noise a Delta Sigma has compared to a Mulitibit, that it needs to get rid of. Even the 6 bit hybrid Delta Sigmas.

Sorry just noticed you did.

Furthermore, as this manufacturer states 90% of the circuitry and the major part of DAC performance is all in the ANALOG design (so according to manufacturer much of the performance is NOT even related to Multibit R2R NOS vs Delta-Sigma digital conversions)

Not as far as MoJo Music thinks when doing Redbook on both.
" When a PCM file is played on a DSD or Bit Stream Delta Sigma converter, the DAC chip has to convert the PCM to DSD in real time. This is one of the major reasons people claim DSD sounds better than PCM, when in fact, it is just that the chip in most modern single-bit DACs do a poor job of decoding PCM."

I have purchased and built 2 Dacs from diyinhk.com    both of these Dacs are very good.  I am currently using a ES9018K2M Dac, the only thing that I have compared to this Dac head to head is a Wadia 121, but it isn't close, the DIY Dac is noticeably better.   They offer 4 or 5 models of R2R dacs with decent parts quality and FIFO reclocking... I may fold and try one of these,  It looks like that the kit, a case and power supply may me around $300 or so.  I haven't added it up,  but it won't be crazy and right now, I'm happy with the quality... I need to research the chips that they use...They do have a 1704 Dac, but the Chip is not included,  The 1702 Dac does include the Dac chip as well as the as well as the AD1856,  AD1862, AD1865 and TDA 1540.  

Tim,

The 1704 is impossible to find anymore TI discontinued it years ago.  There are many fakes around but have been able to find a few genuine in the UK.  Use extreme caution if sourcing BB1704.



Best of Luck

Hi Peter,   thanks for the Advice, I saw a pair of them about 6 or 8 months ago.... What about any of the other R2R DAC chips  that I listed,  are you familiar with any of those.  Have you played with Manufacturing a DAC?  Just curious to get your thoughts. 

The 1704. There are many fakes around but have been able to find a few genuine in the UK. Use extreme caution if sourcing BB1704.

I think this could be a bit of a rumour, as there is nothing cheaper that would work with the same pinout as it, that it can sub’ed for.
