THX Caught With Pants Down Over Lexicon Blu-ray Player
SchlimpyChicken writes "Lexicon and THX apparently attempted to pull a fast one on the consumer electronics industry, but got caught this week when a couple websites exposed the fact that the high-end electronics company put a nearly-unmodified $500 Oppo Blu-ray player into a new Lexicon chassis and was selling it for $3500. AV Rant broke the story first on its home theater podcast with some pics of the two players' internals. Audioholics.com then posted a full suite of pics and tested the players with an Audio Precision analyzer. Both showed identical analogue audio performance and both failed a couple of basic THX specifications. Audioholics also posted commentary from THX on the matter and noted that both companies appear to be in a mad scramble to hide the fact that the player was ever deemed THX certified."
modded down? check my fact! oh right, facts don't matter here on slash.
seriously, check my facts, guys. you'll find that i2s DOES use rj45 connectors on some audio gear. audio alchemy used mini-din connectors but it was the same idea (i2s link between transport and dac).
before you mod down, please do research. THX (lol)

take a deep breath and calm down a little.
read up on spdif, jitter and i2s. come back when you've prepped on the subject matter.
this is NOT ABOUT ETHERNET. m'kay? rj45 does not always (!) mean ethernet. sorry but some manuf's DO overload that connector for other purposes.
you can argue if the diff in wire length in i2s is *audible* but you cannot argue that having equal length wires on a timing critical DAC can't be helpful. having signals reach the endpoint at diff times is BAD.
please read up on digital audio a bit before you foam at the mouth at people.

when you dislike the facts, do you usually throw a tantrum about the poster?
there's logical fallacy for that. ...left as an exercise to the reader.
no, I'm not self-modding. sorry to burst your bubble but I really do know a thing or two about digital audio and the mod-pointed ones apparently see that.

"It is now safe to switch off your computer."
but I can tell you that the only clock that matters is the one driving the audio DAC,
you omit source-related jitter?
you're not a very thorough person, I can tell.
hint: you can't fully undo jitter at the reclocking phase. you can attenuate some but if the source adds jitter then you can't magically take it all 'back' via reclocking.
you are mostly right in that the BIGGEST effect on jitter is at the receive end between spdif receiver and dac.

You're the typical audiophile who is still thinking in analog terms
no, I'm not. I work in both analog and digital domains. I'm not confusing a single thing here.
I never once talked about distortion in wires (since there isn't any in digital) or s/n or frequency response or channel sep. all those would enter into an analog discussion of wires.
I think you're the confused one, here.

well, a lexicon (LOL!) only works when you know the actual definitions of the words you use. ;)

>>>ahem. as both a designer and builder of digital audio equipment, I have to say you are DEAD WRONG.
(falls over laughing)
Oh that was good. A digital audio designer? Yeah. I believe that. Well then you should know that digital audio is self-correcting. It does not matter if the twisted-pair wires are unequal or equal, because you will get the same result regardless. That's the advantage of digital audio - it's unnecessary to buy a $500 cable because error correction makes even a $5 cable work perfectly, such that the received bitstream is identical in both cases.
Stupid audiophuck. We're not in the error-prone analog world anymore.

Clue: do actually believe that a band who's musicians use different length guitar/mic cables cannot possibly play in time?
wow, the 'experts' here are really keeping me busy helping them re-learn things.
musicians playing realtime do not have the same time constraints as digital audio at, say, 192khz and 24bits. with such a high samplerate, having the clocking be precise DOES matter.
otoh, musicians are not playing in the digital domain and you're not trying to align word-edges in a serial stream.
you could not have made a worse analogy. even if you used cars ;)

in this context 'twist length' MEANS wire length.
ie, the 'twists' (read: wire pairs) are diff lengths.
please don't ask us to explain how english works.....

No, no, that cable actually works and does improve your audio. The only problem with the Denon cable is that they've wasted money on pretty packaging. I, on the other hand, can sell you a similar audio-quality cable without the pretty packaging for just $450. For an additional $200 I'll spraypaint it in special audio-improving green. Remember; audiophiles are always right if they are rich.
