Loogie.....your CD PLAYER has a S/N because is a DEVICE.A cd(=a piece of plastic) doesn't have a S/N ratio(that's what i said).In digital devices S/N ratio is heavily influenced by the quality of converters.That's why a Nakamichi usually costs a little bit more than some crappy cd player bought in a supermarket.CD has not error correction?I recommend you some good book, if u fancy that!Just look for interleaving theory and calculation of P and Q using Reed-Solomon polynomial division.On professional DAT you can even read the amount of error correction(Nagra). Computer speakers have 20-20k freq resp., car speakers have 20-20k freq. response, my granny's radio has 20-20k freq.resp....do you know what freq. resp. is? can u tell if your cartdrige behave linearly around 50Hz?how many dB is far from linear response at 20 Hz?Pssshh...just keep it quiet:u'll never find 20Hz on vinyl. Need some more manual, mate+don't believe the hype |

Looks like noone is going to happen until DVDAudio takes off... Suround sound, 24 Bit sampling...(i..e 16.7 million levels instead of 65000.... Plus 96Mhz rather than 44.1.... mmmmm....that should capture everything!!!... Fuck me it's the Phuture!!!!!.... (Another 20 ys and maybe DJ's might be tempted...) ...:).. |

96Khz.... I mean....(t think...) Anyway, it's gonna be pukka.... and think of all that space on a DVD as well.... Several Gigs I believe!!!! |

For every cd that I buy I try to get it on vinyl too!!!! It's the curse of being a DJ !!!THE BARON HAS SPOKEN!!!!! I GOT DUSTY FINGERS !!! |

6dBspl Agreed S/N ratio applies to the cd PLAYER!, I was not meaning the CD itself. An audio CD has no kind of error correction on it. Sure, a player can have a bloody good guess at section it's just failed to read but the disc itself is just a digital stream. If there is a big scratch but you don't hear it then the player has just invented what it thinks might be there. Thats NOT error correction Agreed it's a different story for CDROMs which have interleaving You seem to be approaching this from a studio angle. I'm a hifi enthusiast. No device behaves linearly throughout it's frequency response, that would be perfection. BTW a cartridge can pick up 20Hz, it's just a magnet and coil. But you probably can't cut a 20Hz signal on vinyl, also the stylus would be thrown out of the groove. I reckon my speakers are pretty good B&W DM603 S2 but they have a freq-resp of 48-20000Hz |

CD's, because I can make my own custom mixes, they're portable so I can take them with me wherever I go, and I can listen to them on my discman wherever I go. |

CD's can produce rather insane frequencies. The Flaming Lips's "Zaireeka" is a great example. It's a four disc album where all four CD's are supposed to be played simultaneously (or in any combination that you feel like trying), and one of the songs on it is rather disorienting. One disc has frequencies of 20hz and 14khz, another has 10hz and 14khz, and a third has 7hz and 10khz. The last disc has "normal" frequencies. The liner notes warn that infants shouldn't be around while the song plays, and that none of it should be listened to while driving, weeeee! I've just started buying vinyl stuff recently, but it's either something that's collectible, something that I can't find on CD (A 60's group Rhinoceros only released their stuff on vinyl and it's been out of print for a loooooong time), or something that's good but dirt cheap. But I much prefer CD's, ?yayrahsdf0pi[01/ |

vinyls r shit. they can contain only 22 minutes per side or so, they r much more sensitive for scratches and they produce more noise that's why I buy CD's of course vinyls r nice as a collectors item..... |

Well, i can see your point.You're absolutely right when you say that mine is a "studio angle" cuz this is my job and also(sigh!)what i'm studying at the university.But let me tell you my point of view. IMO cross interleaving is a "form" of error correction.In fact, during AD conversion the binary words are not stored in the natural sequence but are "interleaved"(i.e. their order is artificially changed according to a specific algorithm).During DA natural order is established.Any error will be spread out over time.This "coding" is written on the medium.The "writer" is the encoder but the code is on the medium.This is called C.I.R.C.(as you know).Then checksum or parity block are inserted into the stream of samples.Each binary word may have 3 parity blocks connected to it .These parity blocks are actually stored together w/ the samples on the storage medium.Therefore the error correction code(again) is on the CD.The encoder/decoder read it in the "proper way".If C.I.R.C. fails then you can have(on your cd player)interpolation, hold, mute, etc.(on modern CD players well beyond a modest guess).No device behave linearly-that's the absolute thruth..and that's why u shouldn't listen from the hi-fi point of view.If you're analyzing a loudpeaker in 90% of cases "hi-fi" is the less linear one.In fact, hi-fi are designed, built and produced to be flattering not honest.That's why hi-fi tone controls are shelving 6 db/oct(average).My monitors have a +/- 1.5 dB between 37-22k(trust me, this is freakin' good).What i mean is:if u forget to mention that +/- x dB, say :e.g. "my speakers have 20-20k" means absolutely nothing.In that sense an average monitor behaves more linearly compared to a hi-fi speaker.About the cartridge, you wrote what i underlined in the previous one:20Hz won't go on a vinyl so.....I'm not a hi-fi expert but if you read your free field freq.resp. and the relative difference(in dB) throughout the (theoretical)linear response zone, you'll find out.However i didn't want to start a c |

..erm..as i was saying..this is not a crusade, it's just i hate hi-fi people(JUST JOKING!!).Take care mate P.S. Don't spend a fortune in esoteric cables |

Here's what Brian Lustmord (dark ambient composer) has to say on the matter: "I still think that digital recordings sound superior. Nobody can convince me that a piece of black plastic with a needle being scratched through it can sound better than even current digital. Analog looks better on paper but as far as the sound once it's been transferred from tape onto vinyl ....Of course I do accept that an analog master tape can sound superior to digital, but if were talking about a domestic product, then digital is superior." |

It's better not to confuse digital recording with digital mastering.You can record in the analog domain and mix/master in digital.Even with a pro 2" 30 ips tape the range of applications is not so wide therefore analog very often is not better than digital |

6dBspl Don't worry I'm not a hifi spod! At the end of the day I trust my ears rather than figures. Yeah, fancy cables = dissimilar metals = a battery = bad hifi. They don't tell you that in the shops though. I would of liked to have done that kind of thing at uni. any good? |

PS what's your setup? I have: Arcam Alpha 8SE CD Creek OBH12 passive preamp 2 x Rotel RB981 power amps in b/m B&W DM603 S2 speakers No flashing lights or tone controls! |
