Yamamoto YDA 01 DAC


Is there any Agoner have this Yamamoto dac and could share his comments on how its sound?
Thanks

Lewinskih01,

Not the first time and won't be the last. Seen it too many times already.
A pity a thread about Yamamoto Dac is becoming the thread to find out info on the Metrum. I won't be surprised if this one disappears too. I'm well aware of the reported nice pairing with Audiophilieo 2 and even better with the more costly Off-Ramp thanks to one enthusiastic Aussie user.nSomething to chew over.

Charles,
I was a little concerned about the potential performance of the RBCD as most of the good report is about the hi-res playback but i am glad it is working out well as it is.
I find enormous positive effects every time again when replacing the (good) standard clock in a cd player or transport of DAC with a "super clock" The best Quality/price ratio to my findings is The DEXA Neutron Star clock (200 femto seconds) accuracy but also with good phase characteristics and ditto pws. It made my DEQX "sing" and before that my TEAC transport. I have the Metrun Octave which does not ( to my surprise)degrades the DEQX but with super clock installed. I know the Octave is a follow up form the quad/dual Metrum models, which are really cheap ( 300 dollars for the dual which is obsolete by now) The better models since then heave a better pws and more DAC chips in parallel, but I truly expect the same clock. Now I suppose the Dual or the Quad Metrun to have a nice clock but not to be compared to the better (much) more expensive "super clocks" So in a way it MUST be advantageous for owners of both the Yamamoto or the Metrum to replace their default clock? Even the M2Tech HiFace bettered by John Kenny has at its best "nice" metal encapsulated crystals of probably 30-50ps. The Off-Ramp ( I suppose it is a M2Tech design as it needs M2Tech drivers) is intelligently nodded by Steven and he has replaced the clocks for the best he could find. The audiophilleo 1 and 2, the Burson DAcs publish a clock of <10 ps. Which is probably 5 times more accurate than mainstream modern Dacs. Most manufacturer's do not (dare) to publish the specs of their clocks which may run into the hundreds of ps. It is not only the accuracy of clocks which is important but it is an indication (being the most popular property of a clock) of the seriousness of the manufacturer how to handle digital processes. It becomes mainstream knowledge by now that the clock IS the major reason next to power of digital beauty or lack of it. I would not be surprised at all the Yamamoto or Metrum with a super clock to be the last DAC you need sound wise for the coming 10 or 30 years if the 44.1-192khz format does not disappear.
Kyrill1,
I have no idea what standard clock is placed in my Yamamoto but it sounds so good. If a clock upgrade improves the sound I`d be extremely impressed.
looking at the pictures of the metrum octave in the 6moons review i can't see any crystal clock? perhaps it cames from an erase chips ? any idea?
I did not open yet the Metrum, so I don't know its clock. I CAN predict if it is a clock under or equaling 45MHz (unless much more complicated order processes for custom cristals) it WILL be bettered by a super clock unless the strange über freq Metrum DAC has a very (much higher) clock than the normal range between 6 and 45 MHz.

As for the Yamamoto, I am 99.99% sure it will be considerably bettered by the DEXA Neutron clock with its own dedicated accurate stable pws. The most worst thing that can happen with a better clock is that the improvement in SQ is less than anticipated mostly happening as the sound reaching our ears will always be limited by the weakest link in the stereo chain
