In any case, from home transfers it is clear that the analog signal differs greatly from a digital source when strictly considering non-musical program noise. I'm not questioning what you found to be true with *your* transfers, only the universitality of it. I snipped out most of the thread becuase anyone interested can go back and read. This back and forth is getting unmanagable. Anyhow, to recap: I claimed that when recording from a turntable to a CD there exists alot of analog grundge that is heard and is also shown graphically by VU meters. This stuff is non-musical noise. Now it appears that you are arguing the validity of this? My suggestion: take a turntable, any turntable, and get yourself some analog to digital software. Use any album you like. If you want to replicate my results then I'll tell you that I use Audacity on Linux; I'm sure there are many other similar applications out there you may use--even Windows applications. :-) Next, place the stylus in the lead in or the lead out groove, or any silent passage you like. Finally, watch the vu meters bob up and down with peaks around the -40dB value when there is supposed to be "quietness". It helps to have a good set of headphones for monitoring. I use Sennheisers. Once you have done this several hundred times, or even just once or twice, then post about the "universality" of the experiment. Yep, the behavior you see is not unusual; you're seeing the surface noise of vinyl, which even for the *best*, *cleanest* LP is noisier than digital silence. It *is* a universal phenomenon. Vinylphiles IME are loath to admit any deficiencies of their favorite medium, but to deny the universal existence of surface noise in vinyl, is to be, well, in denial. Please cite one example of anyone denying the existance of surface noise. Well, here is what you said: "Kind of a broad claim based on limited experience don't you think?". That was in response to michael's statement that there is noticeable noise observed from LP systems. Seems to me that you were at least questioning the universal existance of surface noise... Then you are mistaken. I was questioning the notion that his experience was indicative of the best the medium has to offer in performance. His statement wasn't that there was just noticable noise but it gave very specific meansurments of how much but that was based on his records on his rig. I was simply pointing out that this limited experience is not neccessarily evidence of the limitations of the medium but just his records on his rig. Michael's experience was that the LP noise is very noticeable on a digital readout as soon as the needle contacts the "lead-in" groove. That is universally true. You seem to be saying that on some recordings/set-ups the LP noise is not noticeable this way. That's quite an extraordinary claim, given that the surface noise is 20 dB or more higher than the sensitivity of today's 16-bit or higher A-D converters. That's not an extraordinary claim at all as anybody with a really good vinyl rig and properly installed line-contact stylus can tell you. The noise simply becomes virtually inaudible at any normal listening level during normal playback and even between tracks, no matter what the meters show (and I can see it plain enough on my Marantz CD Recorder). Can you cite any example where the vinyl noise cannot be heard? Do you live in the L.A area? I'll demonstrate it for you. Given the easily measureable noise floor of vinyl, you need to listen more carefully... No, Chung, you need to listen to a few really good top-end vinyl systems before you start in based on "theory". Digital capture and display of vinyl transfers simply makes it visible. It can be 'heard through' and thus ignored, but it's always there. It is not the same for all records and all TT rigs. That was my point. It is the same in that the noise is always there. It isn't the same in nature and level for all rigs and all records though. It can always be heard, no matter how expensive a rig you have, or how clean and pristine the vinyl is. I disagree. It is not always noticable. You perhaps will be the only one with this belief. Nope, count me in...and virtually every audiophile who continues to enjoy vinyl. |

Thanks for agreeing that the noise is noticeable on the meter, even on your presumably SOTA vinyl rig. Mr. Wheel seems to think that not all vinyl setups have noise that show up like what Michael saw. That was the extraordinary claim. Can you cite any example where the vinyl noise cannot be heard? Do you live in the L.A area? I'll demonstrate it for you. Given the easily measureable noise floor of vinyl, you need to listen more carefully... No, Chung, you need to listen to a few really good top-end vinyl systems before you start in based on "theory". Boy, there again is that rather contemptuous assumption that anyone who understands the inferioe noise floor of vinyl has not lisrtened to top-end vinyl... And it is not just theory. It's theory, measurements and listening. Digital capture and display of vinyl transfers simply makes it visible. It can be 'heard through' and thus ignored, but it's always there.

Nope, count me in...and virtually every audiophile who continues to enjoy vinyl. I enjoy certain vinyl records (and I have been listening to them for almost 40 years), and I always notice the noise. But of course whether one is bothered by that noise or not is a separate issue. |

No, it's audible any time the music is quiet, as anyone in possession of a high-quality vinyl rig, but *not* in possession of a pro-vinyl agenda, will confirm.

Tired old strawman argument, and absolute rubbish. It can always be heard, no matter how expensive a rig you have, or how clean and pristine the vinyl is. I disagree. It is not always noticable.

Nope, I enjoy vinyl, otherwise I wouldn't have a decent vinyl rig, but I do not choose to blind myself to its *inherent* flaws. I pity those who find it necessary to stick their heads so firmly in the sand - this ruins treble reproduction! :-) -- Stewart Pinkerton | Music is Art - Audio is Engineering |

No, it's audible any time the music is quiet, as anyone in possession of a high-quality vinyl rig, but *not* in possession of a pro-vinyl agenda, will confirm. First, I'd like to comment on the notion that, at normal listening levels, vinyl noise is inaudible. I think that in a home environment with the usual ambient noise this may be true most of the time. Especially if one is not really paying attention. On the other hand, using headphones noise is quite pronounced during low level passages and in between cuts regardless of whether one is critically listening. The fact that in a normal home environment this gross noise is masked really makes me wonder about the critical abilities of those that claim to hear sonic differences from devices such as interconnects, or amplifiers whose level of distortion is infinitely smaller than what we are talking about here. I expect that some of those who argue about how imperceptible vinyl noise is are the first ones to hear differences among items which, under controlled conditions, make no contribution to the sound at all. In fine, components that, if they have any measurable distortion at all, the measured distortion is so low as to be meaningless. In any case, there is obviously a big difference among records regarding quality and quantity of noise. With the V-15xMR cartridge tracking at one gram (plus another half for the damper) I measured the following: A brand new, only played once copy of "John Coltrane Live at the Village Vanguard, Again"; 180 gram Virgin Vinyl "Audiophile Remastered" Impulse disc: silent grooves peaked at -33 dB below 0 (where the loudest passage on the disc registered -2dB below 0. During the quiet "Intro to My Favorite Things" passage, surface noise was audible both on headphones and listening to my Boston Acoustic PC speakers (about 2 feet away). An almost new "played a couple of times" copy of "Sound of Joy" by Sun Ra and the Arkestra on Delmark--a standard LP with no pretensions of being audiophile grade. Here, the silent tracks peaked at -18 dB below 0. On this record surface noise was even more obvious. Are my measurements trivial? I think not, but anyone can say anything, so please don't take my word for it. Indeed, for those of you arguing that these artifacts are less than important, or somehow only valid for my specific set up I'd like you to provide your own measurements for the newsgroup. I for one would certainly be interested in reading about how a "modern" rig measures up when compared to a 30 year old Thorens TD 160 (although it does have a new belt, an aftermarket felt mat, and one of those fancy pseudo high-end weights* that sit on the top of the record :-)). *it's only pseudo high-end since it came from Audio Technica Signet and only cost about $10.00 new. I've seen real high-end weights that cost 10 to 20 times more, but before I spend that kind of dough I first need to save up to get a set of those magic wooden thingys to place under the turntable. You know, the ones with the funny name and that are supposed to improve the sonic pace and the timing, whatever that means. michael |
