New TV: what to do with TOSLINK optical output


Dumb questions incoming: I got a new TV that only has optical out, but I got no optical input on my Cambridge Audio 640A; Do I need a newer receiver or a dedicated DAC to convert the optical out to regular RCA? I see even the new CA receiver (851a) doesn’t have optical input.

Or should I swap to something like the hegel h90 or CA CXA80 with tons of optical inputs?

That's a lot of money to spend when $8 will fix the issue IF the OP is happy with his present receiver and sq from it.

Now obviously if the OP fancies an upgrade of receiver while they are at it then by all means...….

Yes, looking at the manual from your link, the default setting will be "auto". As I said previously, that will need to be set to PCM. Then the FiiO D03K DAC that I recommended will work. It comes complete with power supply for the $20.

Most of the budget DAC's like this look and feel cheap, but not the FiiO D03K, it actually has a quality metal case and feels solid.

That FiiO converter does not look bad either maybe for few extra dollars that maybe the way to go after all.

And if it does not pan out as its sold by Amazon free returns!
I'll grab one of those FiiO converters; I'd love the Hegel but I'm not sure I'll hear the difference and would rather save the cash. Thanks much for all your help tls & uberwaltz

I use this excellent Toslink cable:

to go from my smart TV to this reclocker (which lowers jitter for dolby digital as well as PCM):

Then this low-jitter signal is sent using my excellent $275 BNC-BNC coax cable with adapters to my SS processor. It is important to have a 4 foot cable to reduce jitter from the cable. Incredible surround-sound for movies.

You could also cable to a PCM DAC, but I would use a Synchro-Mesh reclocker instead of the iPurifier if you only need PCM playback. Lower jitter.
