Re: Why McIntosh use CS8416?
My guess is they used it for convenience, since they needed to multiplex multiple SPDIF inputs.
The ES9008 has no provision to multiplex SPDIF.

I checked this Digital Interface Reciever IC, it was CS8416.
I wonder why McIntosh uses CS8416 conventional PLL DIR-IC, because ES9008S has very nice non PLL / Time stump based DIR circuit.
Do you know who it is?

I'm confused. What is the complexity of multiplexing and SPDIF bit stream? Unless, perhaps, you're worried about transients generated if you merely switched them with a digital mux.

It's not that its particularly complex, but by using the CS8416 you can keep the ES9908 in one mode, namely PCM/DSD. This simplifies things quite a lot.

Re: McIntosh MCD 500 inside view
A few questions:
What's under the little shield on the circuit board (assuming microcontroller)?
Where is the ESS in the physical layout?
Can you make out any markings on the back of the Toslink connector (inside the case)? I am wondering what they are using.

nagaesan,
Are you able to see how they derive AVCC(3.3V) for the ES9008? Did they use the same approach as the demo board?
Thanks for the info!
Cheers!

TOS-Link reciever device of MCD500
Recieving OPT Device is this.
I do not know this is 4times speed(DVD-Audio 192kHz is OK)
or 2times speed(DVD-Video 96kHz)
But I already checked it, MCD500 can recieving 192kHz 24bit.
How I checked it, that I build up Audio PC, installed RME HDSP9632 sound-card.
RME HDSP9632 support 192kHz24bit
And I used "Adobe Audition" sound editting software.

OPA627 on ES9008S eva-board
Today I changed I/V OP-Amp on ES9008S eva-board AD797 to OPA627.
I think AD797 is a nice low noise good performance OP-Amp.
But I want more faster OP-Amp for I/V stage.
I changed I/V OP-Amp, AD797 to OPA627.
OPA627 is high slew rate and short settling time than AD797.

AD797 or AD825 or OPA627
I have 3 ES9008S eva-board.
No1. board is not modify, this I/V stage is AD797.
And I put this eva-board in a silver color chasis.
No2.board is modified I/V stage, AD825.
And I put this eva-board in a black color chasis.
No3.board is also modified I/V stage, OPA627.
This eva-board is naked.

ES9018 Sabre 32
Hi,
there's a company called ismosys.com that has the chips and the
evaluation kits for sale:
http://ecommerce.ismosys.com/ordering/index.php?manufacturers_id=34
Can't tell whether they are 'actually' available.
The kits are quite expensive too.
