In principle, it's a system design decision. But those two oscillators are way cheaper than the silabs programmable oscillators....
take it there 22/24 oscillators then or is the freq divided for xmos?
any hopes for an oem with just i2s in with two 22/24 mhz ndks/or external input and no digital filter
surely that's comparatively simpler/cheaper? with a wider market?

apologies for use of band name i only meant it as an example
its not my intent to diss your oscillator choice
and its your right not to discuss your headphone dac here i understand that
just something that i was thinking about this last while
that there should be a market for i2s only dac modules with an external oscillator input at 22/24mhz
with no digital filter to single ended
ability to use two for balanced setups
priced under 100 euro/piece

It's ok to ask, as long as nobody get offended if I don't answer....
That would be the dam1121.... There is always are market for lower cost products, but don't expect EUR 100 anytime soon, that would require some advanced engineering and higher volume....
Sören: the reason people are giving NDK as an example is because they are cheap, small and easily available. And there are phase noise curves published. Seiko-Epson may be as good, but I have never seen any curves of them.
LOL
im sure most of us have thicker skin
is there any product info available on the dam1121
i thought it had almost as many features as the diy board?
Yes, but there are also a few that easily get offended, especially if they feel ignored....

Not much yet, but as soon as the dac1101 start shipping I'm going to finish docs and firmware for the dam1121 and ship that too, already have the first small batch of production boards....
its official i cant read
probably would have went more barebones on it
i can understand the cost difference would be negligible vs the 1121
and after developing the 1121 your unlikely to make yet another feature reduced version
ill try the 1121 and see

Yes, i think a few dB worse than NDK onyl. But they doesn't seem to be avalible in the 22/24 MHz range. only 11/12 as far as i can see.
light dawns
the 1101's firmware is very little different
Your either using a fpga generated audio frequencies to run the xmos or your using 45/49 oscillators and a frequency divider to feed back to the xmos which is selecting the frequency in either method

OK I know you might not answer this one but I have to... do you use reclocking after the fpga in the 1101?

Dear Soekris,
Notice the size of this separate. Just boring black 2U box. Well they did manage something special that i still remember after all these years. It's not about design overkill, but simple things , just a bit of personality.
It's up to you, don't get me wrong, I have subscribed to this thread from day one almost. I admire your work, and even if i don't own one yet i have a positive bias.
For ready-made products, you can be happy saying , "well it's readable", "well, it's really small you know" ( hmmm text does'nt even align with leds gorsh ) or go just the extra inch (I'm not even talking miles here) and make history. Up to you man.
PS: Kudos for all you've done, ( and also to the community here)
(Hint about text orientation inside)
Best,
Thomas
