New TV audio output.

Hello Everybodypeeps.

I'm about to purchase an enormo Samsung curved-screen telly. It's got an "optical" audio out.

Am I right in thinking that the appropriate cable will plug into the back of my NDX5s digital input for TV audio from thence to the Preamp?

A curved telly ... really?  Be sure you want a curved telly and you're not just falling for gimmicks: living with one is different than falling for one in the store - remember you will be viewing at home from a much greater distance than you probably see it in the store.

(Sorry off topic)

I've found some optical cables to have 'plugs' of variable fit, some tight, others loose and floppy with a tendency to fall out. Worth getting one from a seller who accepts returns in case you get one that's a poor fit. I'm currently using one from Flashback which fits well and seems to be of decent quality - it's glass fibre as opposed to POF, and very stiff, kind of a NACA5 of optical cables.

Make sure the TV can do 2Ch PCM output. My Panasonic TV only does Dolby Digital so will not work with Naim DACs (I use a Qute). Even if I set to 2Ch it does 2 Channel Dolby Digital. 

You can get either HDMI to toslink converters or HDMI to STEREO only converters. I have a Panasonic also going into my NAC N172, and on Netflix get the Dolby "chatter", even when I select stereo PCM on the TV and Stereo on the Netflix options. Tried one of the HDMI converters/adaptors and it worked! Cost me $89 here in Perth Australia

Works fine on my Sony TV, with good lip sync too....

Indeed it works well with my LG TV too (optical into my NDX)... with regard to the point on lip sync on many quality modern TVs it's best to get the PCM SPDIF stream from the TV itself as the TV will adjust the delay in the sound to suit the video processing thereby providing the possibility of good AV synchronisation...

Yes indeed. That is also my experience. Taking the feed from the sky box or DVD gives terrible lip sync with my Sony but taking it from the TV itself is fine.

Yep, that fits with our experience.

TV video processing always takes longer than TV audio processing. Some TVs have a lip sync adjustment setting, but others only have a built-in, non-adjustable delay (like my Panasonic Plasma). The hard-coded delay on my Panasonic toslink output was okay with a Sonos Playbar (who's DSP processing contributes to the audio delay, which helped in my case). At least, I never noticed a problem. But when I swapped out the Playbar for a UQ2, I had to add a Felston DD740 digital delay box (to the tune of an extra 100ms of delay).
