I have added a couple new components to my system and have ran out of optical inputs(only2 optical inputs).


Is there any difference (sound quality) between using the optical inputs vs the coax inputs?


I have hooked up my HD-DVR to the digital coax input. I had it hooked up to the optical input before. Will there be any difference in sound quality?



Thanks in advance.

The wheels on the bus go round and round, round and round, round and round. The wheels on the bus go round and round. All day long.



No offense intended to the OP. But, there are plenty of previous threads that have addressed that question.


But... when you switched from optical to coax, did YOU hear a difference in sound quality?

I have heard from many that they prefer Digital Coax over Toslink Optical. I have also heard from many that there is no difference. I have never heard any say that they preferred Optical over Coax.


I have used both, and to me, there was no difference.

There are 2 more devices in the signal path for each optical connection (1 on either end). To me using fiber for audio is like using glass for water pipe.

The fiber in consumer electronics is plastic.

Except most of the music or movies you listen to was mixed with fiber in the chain. It is an accepted medium and does what is needed. It has ZERO bearing on the sound.

Zeros via Toslink--

00000


Zeros via coax--

OOOOO


Some prefer the fuller and more rounded sound of copper, while others like the lean uncolored sound of glass.


Personally I like Columbia Crest, Grand Estates, Merlot--a smooth tipple with good mouth feel for less thean $10.

Glass is not only lean and uncolored, but transparent as well.



Cooper, on the other hand, has a nice sheen to it.

Thanks for all the info. I guess when you run digital its ALL or Nothing.


If you hear it. It is working.


I was just curious if they used different algorithms or something funky like that that would make them different.


Since this doesn't seem to be the case, it looks like 6 vs half a dozen.


I am partial to the optical, since you don't risk any extra noise in the signal, but the coax seems to sound the same!



By the way, I didn't mean to open a can of worms with this post, but didn't have time to research all the posts, and thought it would be a quick response (which it was)


Thanks again. And keep that bus driving ....all though the town.

Depends on what you are playing. The optical output can only convey 2channels of lossless audio. More channels would be lossy.

All i play is movies using the best sound available on the disk. I do not play audio disk at all so hooking up all the audio cables is a chore if audio is not improved that much.

It looks to me as if the Oppo's 7.1 capability is for Dolby EX SD DVDs. The spec sheet says--
7.1-channel audio with Dolby Digital Surround EX decoding
It that is the case then it is unlikely that there will be any advantage to using the Oppo's onboard decoder/processor, as opposed to sending the bitstream to the Pioneer via either optical or coax connector.

I would run the optical cable directly to your receiver's DVD optical input. That way, when you select that input, your receiver will switch to the full surround sound.

Using a multichannel analog connection to the receiver's external inputs is probably not necessary nor useful for you.


Also, does your receiver not have an HDMI input?

Is there another way?

Agreed.

Good question.
