Well you're out of luck on that request but I do know for a fact that the Headphones volume became anemic when the Double Helix Cable i've been using w/ the HE 6 was replaced w/ the supplied stock cable. I'm sure the DHC cable is light year's ahead in terms of the wire geometry used .(which I find to be pretty impressive just to look at)
I'm pretty sure there will probably be pretty significant differences in the comparative measurements of the wires ,but I'm just not equipped to take the measurements
(So they decided to give the Bifrost a "real" output stage. The Bifrost is the DAC that got me interested in NOS DACs)

By the way the KMN 4399 which is what the Bifrost uses is not a NOS dac. It is a Delta/Sigma dac with resampling and digital and analog filtering, none of which NOS dacs have. Most NOS dacs use the old R2R ladder chips like Audio Note use or the Terada uses. Does not mean that the Bifrost is not an excellent dac because it is

  Are you sure about that ? I seem to recall the discussion that (I can't think of his name
  now) he said he could!nt repeat what Mike Moffat said what the felt about ever using
  Upsampling in a DAC so was this all just fictious rhetoric, or do Delta Sigma designs that don't Upsample but are not classified NOS designs exist ?
  
  I believe it may be an AKM 4399 chip that was used, as I had another piece of equipment
  that also used an AKM chip a different chip number but I remember remarking to myself
  " how about that, this uses an AKM chip also"
  
  These are my recollections , but it's been several years.

    Jason Stoddard said this
    "One of the reasons we like the AKM4399 (and 4396) is that they use switched-capacitor filters to provide out of band noise performance that is more similar to a multibit DAC. As far as we know, they're unique in this regard. They're still delta-sigma, but they're a rather nice implementation of delta-sigma."
    Apparently this is a Delta/Sigma dac that doesn't upsample. I tend to classify nos dacs as those that use the old ladder chips but that is just me. I have Schitt stuff for my headphones and it is very good. Killer at its price points
