I want to by a new TV and want some advice

It would require something pretty significant to cause the error correction to fail, wouldn't it?

Pretty much yes. But that would be down to a poor quality hdmi lead (which again, whilst it HAD failed, the picture would still look 'good')

That depends on what the error is.

But when the error correction on a CD fails, it doesn't just sound "not as good", does it?

Short answer is yes (If you think the error correction makes it back to 'perfect' your very much mistaken). Unless it failed completely in which case were back to 'skipping' again
By the way, im talking about hifi cd players. Not computer ones.

CDs use Reed-Solomon error correction.

Well ive not the time to read that right now. But regardless of whatever it says. Even cd players with the same DACs do NOT sound the same.....

Maybe, maybe not. But there could be more to it than the DACs. I would image the analogue output stage would make more of a difference.

I'd suggest you get a Panasonic or a Pioneer. I have a Pana 42PX80 and it's good.

Look at this 'state of the art' cd player
http://paulberry.livejournal.com/2007/12/04/

• Specifically developed for audio data standards
• Up to 5 times fewer data errors
• Less dependent upon error correction

"It is commonly misunderstood that CD data retrieval is all digital and always perfect. ........."
" The audio data is read with a much lower block error rate, up to five times better than ordinary CD playback engines. This enhanced level of data integrity significantly reduces the need for the data to be passed multiple times through the error corrector, generating less electrical noise and improving system resolution. "
"CD Audio was never perfect. For over twenty years, hi-fi manufacturers have been struggling to improve the performance provided by off-the-shelf CD drives designed primarily for data (not audio) retrieval. "
• The digital signal retrieved by the high performance SE platform has a much lower block error rate than is found in ordinary CD playback engines. Because the error correction circuitry needs to work less hard, lower noise is evident in the data conversion process.

Basically. Even if data is corrected, the fact it HAS to correct the data adds 'noise' to the signal.

Its the system at the show which I think was about 1996. I did not have grey hair back then:rotfl:

Sorry I forgot to mention you need to log in first at av forums to view it or the page appears blank.

Hi Berty
I was logged in, but as I was at work it didnt show somehow (they have tons of 'security' on their computer systems)
Them speakers are something else!

With regards to cd error correction and 'noise', I've personally been using a pair of these Pioneer CDJ1000's in a nightclub with a high end sound system and I can honestly put my hand on my heart and say that I have not once heard anything added to the song that should not be there, even on discs with damage so immense you would not expect them to be read, let alone play correctly.
