LP vs RECORDED CD

Post by Snoop65 » Wed Dec 04, 2013 7:46 pm

Rabbit (yeah you Gary!) has often spoke about a cd recorded from a LP sounding exactly the same so I decided to give this a try. I have been making recorded cd's for years for my car or to transfer to my pc but never thought to listen to one against the original lp. I have a Alesis ML-9600 disk recorder that does four sample rates (44.1,48,88.2 and 96khz) , will do Redbook or CD24 and has a built in hard drive. I will making recordings at each sample rate and listen to them against the original lp. I will be doing this on the secret system so I will be able to run lp and digital recording at the same time and fade back and forth between the two, no listening to one then the other.
Ok Lp vs. Recorded CD part one. I kept this first go round simple and only did two tracks recorded at 44.1khz and 16-bit. The first cut was "Captain of her heart" by Double, I chose this because of it's simple but big airy sound and excellent detail. The second track was " Don't let me be misunderstood" by Santa Esmeralda, I chose this one because of the excellent acoustic guitar work, the horn section and there's a lot going on in this track but great detail. I did this recording using my Alesis ML-9600 digital recorder hooked up to my "secret system" which includes my Urei 1620 music mixer, Carver PM-600, Denon DP-DJ101 turntables, Stanton Groovemaster cartridges, Urei 5547 eq's(not in the recording loop) and Cerwin Vega 39P's upgraded with JBL woofers and tweeters.
At first listen, I have to agree with Rabbit they sound the same. I played the cd first then went back to the lp. Then I spent some time with the tracks (over a hour). I started to feel there were differences so what I did was start the record and the cd at the same time so they were playing together and switched back and forth between the two. On "Captain of her heart" the sound didn't seem quite as transparent. The piano notes were not quite as clean and the highs seemed to have a hard edge, not smooth like on the lp. This was actually a small difference but it was there. Moving over to "Don't let me be misunderstood, the difference stood out more. The horn section was not as "up front" on the cd as on the lp. The horns on this record are loud, bright and in your face, they get pushed back on the cd. While still sounding good the cd just didn't have the life of the LP. The acoustic guitars were pretty good on the cd, but the lp had a more real sound. So much for round one.
Next up I will do some recordings at 16-bit and 48khz, then 88.2khz , then 96khz, go to 20-bit at all four sample rates and finally 24-bit at all four sample rates. Then I will move the Alesis ML-9600 from my secret system to my main system and start all over. My main system should be a lot more "revealing". I will also listen to the cd's on my Carver SD/A-390t. Stay tuned!!!

Nice write up Snoop and interesting that you have a setup that allows you to hear it real time one against the other.

Back in my car stereo days I always ran a highend cassette deck in the car and recorded off of cd or lp onto a Maxell high quality cassette. I figured if my collection got stolen It would be $2.00 tapes instead of expensive cd's.

Vance, will the 390t play burnt CDs? My 490t would not.

Have you verified there isn't any eq work done passively in either unit that might explain those changes?

BTW, great experiment man!! Keep us posted!!

Nope no eq in the path Ray. As for the 390t playing burnt CD's , they will play WMA files not MP3. Were the CD's you burned using MP3 files?

Really? Mine won't. I made a CD with WMA and MP3 and it would skip over the MP3 tracks.

My 490t wouldn't play burns from my PC or my Tascam. All were CD copies of CDs. No MP3s or any other kind of file straight CD.

Hmmm makes me wonder what I did wrong. Hell it wouldn't play a copy of Revolver Jesse made and brought to the last Fest he attended.

That is strange. I wonder if it is a thing of one model being newer than the other and the newer ones can play PC made or copied CD's. time to check serial numbers for manufacture dates?

First of all....that was funny :lol: :lol: :lol:

I remember this coming up at CF13, I think it was FrankieD and ZootHorn over at my cabin with some burned disc's and they asked if my 490t would play them. We tried it and it did fine. The 490t has to think about Marks CF12 cd (as in it sets there for about one solid minute before it begins to play) but his CF13 plays perfect. My 490t serial number is 929CO852661. FYI my original 490t that was purchased with my TFM-75 says Februaury 1991 and also has a serial number starting with 91 and the insided looked a little different with none of the plastic guards that say Danger High Voltage etc.

I remember one of the Toms saying the early ones has a better cartridge/disc holder assembly??? Not sure but something to that effect.

I have a good friend that sent me some CDR's he made from the LP's, says they sound just like the LP's. He was right, same damn surface noise, same damn pops and clicks.
