I have made this comparison many times and while the CD-R's sound surprisingly good and in most cases better than a commercially released CD, the vinyl is easily recognized and superior to the CD-R. To be sure, while I have made CD-R's of a number of my records, if I listen to them it is for reasons other than sound quality (ie. in the car, replaying many times for sound comparisons)The difference between a CD-R of an LP and a manufactured CD is indeed about process, and one of the primary differences is that in the case of the CD-R there is a needle physically moving up and down that is producing the signal that is being stored, and the products of that *physical* motion are what is heard.
Follow Ups:
were the cdr's recorded using the same quality of sampling and processing as John's or were they recorded with a less sophisticated recorder? Just asking.
I recorded 45 rpm Belafonte at Carnegie Hall by using RME 9632 sound card, which supports 192kHz/24bit and CoolEdit software at sampling rate 44.1kHz/16bit and 192kHz/24bit. And I played back 44.1/16 version on Sony 777ES with Mark Levinson 360 dac. LP was played on SME 20 with Graham 2.2 arm and zyx air 2. LP was clearly a winner. Since I don’t have 192/24 dac, I played 192/24 version directly from PC. I also played 44.1/16 from PC as well. I couldn’t hear difference between 192/24 and 44.1/16. In order to have fair comparison, I played 45 rpm LP on my secondary system, which consists VPI with JMW arm and Dynvector 10x. LP is the winner, too.However, I would say my experience is not conclusive since 45 rpm is overwhelmly better than 33 rpm. So, the difference between 45 rpm LP and CD copy is so obvious. But in the case of 33 rpm, I expect the difference should be less obvious.

on this point the argument "digital beats analog" falls on it's lights.
If other's can't hear a difference it is because they can not hear very well.
i guess I would suggest that John just stay at home and forget his test with the Rockport. If he can't hear what you hear then it's a waste of time. He's got to face the fact that he has tin ears.
I just want to say that I've been ready to do this test since April 24th when the challenge was made. The challenger gave me only one date of August 12, which I planned on and was ready to attend. Then, less than a month ago he switched to August 19th. I can do this test anytime, but my best audiophile friend who lives in Seattle was not available on that date, so I declined. So far, the challenger has not given me another date. He simply said that since August 19th was not possible, the test would probably not happen until late September or early October. I have not heard from the challenger since.I fully plan to go to Seattle and show this guy what digital can do whenever he decides he is available. However, I would really like my best friend to be at this test session. My friend was available in May, June, July, and the first part of August, but my challenger was not. I am available anytime.
the guy probably thought you renigged. Now with this big cock and bull story about your friend you are becoming a prefessional bullshitter.Why not keep your opinions to yourself until you are reasdy and HAVE taken steps to stress them out.
"You are available anytime" Sounds like when we were kids: "I'll fight you anytime" ... while backpedalling.
You are wrong! The challenger backed out. He told me in April to pick a date in July and August. I told him then that any date would work for me up through the second weekend in August. He picked the second weekend in August. Then, just last month he switched to the third weekend and I told him no dice. I suggested the fourth weekend of August 26th or any weekend thereafter. He said he probably couldn't do anything until October and we left it hanging.You see, O’Malley, you are wrong and you are backpedaling about this whole issue. You cannot provide a single shred of objective scientific evidence in support of your position so you try to change the subject and talk about all sorts of superfluous bullshit. You make jokes about my stereo system, which you have never heard. You talk about A/B tests between commercial CDs and their LP counterparts for which anyone can hear the difference. But you have yet to address the real issue in any objective, meaningful way.
You have not provided one shred of scientific proof that digital sounds better or the same as analog.A poster here has done the exact same test that I lamely tried to do and he claims that he hears a difference. What do you have to directly say to that? Please reread this paragraph and come up with a real answer.
I make fun of your stereo the same fatass way you make fun of people and the same way that you make those tedious, juvenile, digital comments.
Just thought I'd have some fun at your expense ... and I will keep it up as long as you do. It's all about you. I thought you liked the attention.
P.S. You renigged on the challenge by not going; Period. What, you need someone to hold your hand?
"A poster here has done the exact same test that I lamely tried to do and he claims that he hears a difference. What do you have to directly say to that?"So what's the beef jerky?
more than one other person can hear a difference between redbook and higher encoded CD-rs from LPs. The test seems done. The only thing is to admit you have tin ears.
