Carl,

Thanks for the lot of work and info here.

Thinking about your conclusion and look on your preference,
I agree with you that ID40 is the "best" followed by upsampling in the C15(800 and "last" is upsamplng in the v6.
And that all is guilty for new records, not old (not optimised) way to make the A/D conversion when the recording is taken.
And "just" upsample first(in the 800 or C15)
its better then doing apodizing later in the v6--
independent if the first upsampling include apodizing or not?
If so- then apodizing is not better as standard upsampling.

So what do you expect with old sources-the same "ranking"?
If so- then apodizing is not better as standard upsampling even on old records.

Which output of the 800 are you used?

Just try to find a straight logic here
-independent of apodizing/old records or not-
isnt the conclusion from your "mini review" ;-)) that

1)upsampling in the DSP and even "better upsampling technic" in the processor its not as good doing it in/at the source ?(first step)

2)For standard sources "just" buy a HD621-(because upsampling/apodizing in the first step)

3)And want the best-buy C15 and ID40,
because with the ID40 upsampling FIRST is not necessary?

4)So the best is not to but apodizing in the 800,
but install a "network" card similar as the C15 that can correspond with the ID40 in the v6?

5)And take the same conclusion,
but a "network" card in the HD621?

6)Or the final goal and for me the fastest way to jump over the point 4) and 5) install a new "newwork" card in the DSP(even in the top models)?
Thinking so, then it makes sense to have a RJ connection at the speaker.

But WHY making technically unecessary steps between that just frustating customers?
After had and still have all the very bad experiences with M,
I believe the development group is still ahead,
but not the quality of manufactoring and technical service and
absolutly the worstest is the customer service which means management.


Carl,

technically the ID40 and similar card in the C15 "only" avoid the way to transfer the data via SPDIF/AES.
They "just" transfering a file/music different and "open" that different on the other end.
So ALL the story is just to avoid jitter all over?

So why not make a alternate, very basic simple solution here and leave all the SPDIF untouched.
Just make a new controler/digital board in the DSP,
that have a "bigger" buffer and reclock the data.
The "way" of the SPDIF path is here only some mm,
from the regenerated signal to the D/A converter on the same PCB,
and jitter issue here is more a theoretical question I think.
