After reading reviews I decided to get one to connect my Roku to my TV. A little expensive, but I like the results. I think the video is clearer and there is better sound especially on sites like Accuradio.

Digital is digital, if the 1's and 0's can get there uninterrupted, you aren't going to be able to discern a difference.

But, but, but... it was expensive, so it must be better. smile

It has to be better, I'm not getting any 1.2s and 0.5s anymore. Now just pure 1s and 0s. LOL

+1, IBTL. Plus, there's got to be a converter to go from copper to optical, right? I'd argue that means at best you'll only match the performance of a good traditional HDMI cable, and can't actually improve anything. Any conversion or additional connection introduces some noise/artifacts somewhere down the line. Unless you're running insane distances from source to TV, there's no benefit.


De omnibus dubitandum.

Considering that Accuradio streams at 24-32 kbps, the quality can't be all that great, regardless what cable you use. smile

As far as free radio apps on Roku, I think Spotify and TuneIn offer better quality.

I dont get it. HDMI runs on copper. Fiber optic requires an optical digital signal. So you need to go copper to light, fiber optic HDMI, then light back to copper.

Two conversion stages gives MORE chance for errors.

It would likely be great for long runs or spots where fibers give an advantage. But to connect two close by devices, seems iffy.

They are primarily designed for long runs as per your posit. There's an optical converter on both ends of the cable, powered by the device it's attached to.

Yep.

People said that about CD when they came out.

most CD players** for over a decade did not meet S/P white paper spec for noise and distortion for a 16 bit 44khz sample.

They had high error correction and concealment rates.

Time splitting is analogue and its a BIG part of digital data transfer

Jitter is a data killer.

Likely more at galvanic isolation

Too many different GND references going on.

Always tricky with outside cable coming in and too many gizmos plugged in all at different chassis bias
then add in noisy switching supply wall warts

I move stuff around to different power strips, and all %#*&& breaks loose with my audio or video.

Need to read "Zen and the Art of Digital Video Maintenance".

Bought our first big tv at Circuit City (remember them?) and the salesman asked me why would I spend 1300 on a tv and not buy the $100 HDMI so we could get all the wonderful goodness from the tv? Fell for it, didn't know any better.......

My old company threw out 6meter HDMI pro-grade cable by the dumpsterfull that came with the large monitors we rebuilt for
"special" customers

I saved a few from landfill.

I have one on my TV now. Works excellent compared to a Mid grade Monster or a flexible but skinny G.E.
