I met Tori Amos last year, she seemed quite friendly and I asked her to sign an autograph,as she put pen to paper I said to her..you are the best trumpet player out there, she looked at me funny and walked off and now I know why. .
I needed an M scaler! !!!!

Hilarious!

Thanks for taking the time to respond back Rob, so in terms of re-creating the the wave form via PCM through SPDIF how will the M Scaler handle any clock variations. Is the need for an I2S link between source and DAC a bit exaggerated, my reason for asking is if there is jitter from the source transport via SPDIF is there a chance that the jitter could be amplified by the upscaling before it goes to say the Qutest, causing additional distortion?

Or is that too minimal an effect to consider ?

Thanks in advance.

It's too minimal an effect to notice - that was why I was so surprised with Hugo 2 to get the optical to sound the same as USB via headphones. USB gets the clock from the FPGA, but optical gets a new word clock created from the FPGA clock via my DPLL. This ensures it is the same frequency, but ignores the phase, so source jitter is eliminated.

Are there 2 mscaler threads/forums??

Yes. We should probably stop using this one. Thanks to @plinth for getting us started.
