I wish I was better capable of understanding the actual workings of these ICs. Taking into account what Rhodes said about the Wolfson receiver in Chameleon, the way to run it without the TCXO is to use the recovered SPDIF clock from whatever someone is feeding it. I expect feeding it with SPDIF from an Off Ramp will be fine but like Rhodes (and Steve Nugent) stated about most SPDIF, they mostly don't get it right. No telling how it would work with something like the Hiface. A simplified version of the current input board with the Wolfson sans TCXO would be strictly for excellent SPDIF sources which is really what what we're asking for, but there's no wiggle room like the DIR9001 would provide. On the other hand, the Wolfson using the recovered clock might be superior to the DIR9001 when supplied with an excellent source clock. ...Because the DIR9001 has its own clock.
I'd probably be okay with a simplified version of the current input board (sans TCXO), but what about the rest of you guys? I expect Michael will have to have a different board fabricated to suit the simplified design, so it might not be more trouble to ask for the Wolfson or DIR9001.
We probably shouldn't rule out the possibility of finding a way to mod the current input board to do the same thing but I expect most of you would rather have an alternative board to drop into your Chameleons and not have to cut up the proven boards you've been using.
The DIR9001 does a very good job by itself but I believe that because of personal experience when feeding it by an Off Ramp. Bill Allen can tell you about connecting his Pace Car to his Valab and how well it's worked for him. I'm not completely sure it was simple coax SPDIF but I'm reasonably sure it was. He works with serious high end hardware and he's said the modded Valabs can sound magnificent in those systems.

I'm very curious to see how this pans out in the coming months but it's painfully clear that properly installing Steve's I2S mod is for an advanced modder. Steve has given kudos to properly implemented SPDIF and he obviously believes it can work well in his own products. I'd be very happy if we got a proper simple SPDIF input board (sans TCXO) from Michael.

I am assuming the WM8805 works without the clock, and works as well as the dir90001. |

So a future iteration of the Teradak series could/should incorporate a I2S input of the bat and so it would be far easier to use with the Pace car and off-ramp, and even Teradaks own reclocker which uses I2S output (I think). But its good to know that this very valuable upgrade path is possible! |
