**It did with the CDP-101, because only one DAC was used and
shared between left and right channels. All (?) other players
used two DACs (one for each channel) and the delay was not
required. For the record, I just checked the schematic of the
701. The 701 used two DACs. One for each channel. It does not
use a delay on one OP amp. Both OP amp feedback resistors are
15k, paralleled by a 75pF cap. This likely contributes to the
difference in sound quality noted by many listeners (including
me).


** More TW audiophool nonsense.

There is no audible difference and the 15k resistor business is
an obvious red herring.

Just do a tiny bit of math on those numbers.


**If there is no audible difference, why did Sony use different
value resistors in the 101 and the same values in the 701? I
presume you are suggesting that there is a measurable difference,
but that difference is inaudible?


** FFS TW, do the math on those values.

Find the -3dB frequencies and see how far above the audio band they
are and that there is almost no difference in using 15k or 16k - the
caps are only 5% types !!

**You are correct. 5% mica types. The resistors are 1% tolerance.


** For a total of 6%.



PLUS the fact that it is having NO effect on the 11uS offset.

**Funnily enough,


** TW only sees what he WANTS to see, and heasr what he WANTs to hear.


the difference between those two values is pretty
close to 11uS.

** 15k & 75pF = 1.12 uS

16k & 75pF = 1.20 uS.



Those 5% caps are a bit of a problem though.



** FFS, TW has no case at all since the 11uS offset ( exactly half a sampling period ) is NOT affected.


BTW:

For my interest, was it YOU who came up with this mad interpretation or did you find it floating free on the great world wide sewer ?
