I just bought a Felston to correct the lip sync issue on my plasma. I have good quality audio components, Bryston amp/preamp and Thiel speakers. Will running the audio through the processor noticeably degrade my sound quality?

Any opinions/experience on this? Thanks.

I don't think you are in the right forum. Questions regarding audio components are not answered here. You should try the Receivers / Processors section of this site.

No, its a digital signal.
