The cut sounds like it was done as well as anyone could expect. Bravo. Was the full DMM process used (Deutsche Grammophon-licensed plating and pressing, fresh chemistry, etc.), or was it a copper cut with standard processing? |
Quote: |
I've never had the full DMM treatment, but I get things cut into copper whenever possible, and I particularly appreciate the lack of groove distortion. Your reduction of land space is effective on copper, but probably would not fare as well in lacquer -- am I right? |

With the sides cut at 45rpm, do you need to make any allowances for depth as differentiated from 33 rpm? |
Quote: |
Did you need to use an elliptical equalizer or VAL, for example? |

I've often wondered if cutters which were critically damped for 33rpm would "ring" slightly when used at 45rpm. I had been told that when cutting into copper, the stylus had more difficulty cutting the groove at low frequencies, and this required slightly different "tuning," whatever that is, for flat response. I often wondered if that might be one of the reasons the low end sounds slightly more extended at 45. Have you noticed anything you could measure in this regard? |

I have no idea what "fresh chemistry" is but I think it's important to note that to date the chemical process for electro-plating copper DMM blanks has undergone 3 major changes since the process was originally speced out by Teldec in 1982. |

Steve, A thought has just occured to me,When i master anything to lacquer i always do a test cut on a scrap lacquer which i will a/b with the source,When you do a test cut do you use a standard playback stylus for comparisons or is there a special dmm playback stylus,(Obviously the dmm cutting head and styli are different) Jason |

Seems to me that a tracking arm like a cd player would eliminate the stylus angle problem, I'm wondering why they haven't designed turntables with a cross member tone arm that remains perpendicular to the grooves, rather than one that arcs across the surface. Maybe they have, not sure, but wouldn't it be a better design? |

most on this forum already know the following - but for those unfamiliar with the old skool: In a vinyl record mastering chain two duplicate signals need to be sent to the lathe: the first "preview" path gets sent to the lathe's lookahead pitch & depth computer which sets the height and of the cutter head and the spacing of the grooves dependent on the amplitudes and frequency of the sound, and the second "mod" or "program" path - delayed by a half rotation's time (900 ms for 33-1/3 - 667ms for 45rpm) which goes from the cutting amps to the cutting head which etches the grooves into the copper. Originally these two seperate paths were achieved by using a tape machine with 2 seperate playback heads and that had extra capstans so the tape could wind around the necessary length before reaching the 2nd playback head to achieve this delay. This was later replaced in most vinyl mastering facilities with digital delays. The problem though is that pretty much every hardware ddl out there (including the TC M2000 in our studio) is limited to 24bit/48kHz. Enter SAWStudio. By using it as a tranport it's extremely easy to rout hi-res files at their full resolution to two seperate but identical outputs with one of the outputs appropriately delayed. Also critical to my choice was reliabilty - the copper blanks are very expensive to make so I had to go with an app that I knew was rock solid and wouldn't glitch out in the middle of cutting a side. SAW fits the bill! |

Steve, I don't completely understand the need for all this look-ahead delay complexity. It seems that one could just have an algorithm that models the signal path and stylus behavior, crunches the entire wavefile and then spits out a completely optimized control file (lathe control tracks). The audio signal and control signals would then run simultaneously. I guess this delay system is necessary because the pitch computers are circa 1982? Are they analog computers? Thanks, Thomas |
Ronny wrote on Sat, 25 June 2005 18:09 |
Bored? Absolutely not, this is great stuff, Steve. I have some questions. Do you notice any difference in sonic quality by going at 45rpm over 33rpm, any change in the highs and lows like for example taping at 15 versus 30ips? |
Quote: |
Did BL, know when he mastered the vinyl songs that they would be ran at 45 instead of 33 and make allowances for this? |
Quote: |
Also, you touched base on tracking angles towards the inside of the disk, because 45's were typically smaller than LP's |
Quote: |
and the major difference being the outside of the LP between the two, does the stylus angle tend to distort on the outside of the LP, compared to the 45. IOW, is the angle a concern at both inside and outside of the large disk. |

Steve, this discussion has been fantastic and I must admit you inspired me to order the records. They came in a couple of days ago and I've been breaking in a new phono preamp listening to them. How cool. Great job man. They sound really good. I don't think I've ever owned a 12" that was 45rpm but it's great. You should be pleased. I had already picked up the CD and now I'm wishing I had the hi res PCM to compare to. I think one of the best things is the fact that I find myself wanting to turn it up rather than down. (Audioslave, anyone?) Keep up the good work! |
Bob Boyd wrote on Sat, 25 June 2005 22:13 |
Just to be clear, BL's work on the CD sounds great too. I really appreciate that he didn't fall into hyperlimiting. It's competitive but it's not overcooked. |
TotalSonic wrote on Sat, 25 June 2005 13:08 |
...our current system allows us to transfer directly from analog source without ever converting the signal to digital. It also allows us a faster production work flow in that we can do a direct transfer from DAT or CD-R without having to take the time to record or rip the tracks to DAW and pre-analyze them as you are suggesting here.... |

ummm.... might be misunderstanding your post - but actually in essence a cutting head on a modern lathe is "linear tracking" in that it is kept perpendicular to the center point at all times and moves in & out on a fixed straight bar. Best regards, Steve Berson |

Best regards, Steve Berson How come nobody tells me these things..... So doesn't that create a comptability problem between moder vs. legacy vinyl and liner vs. angular tracking? GR |

A quick question for you: in my 10 years in the industry I have developed a general preference for dance records cut in the UK over pretty much anywhere else (for the kind of music I play, this includes mastering houses mainly in the US, Holland and Germany). The cuts generally sound 'hotter' (obviously an essential for the DJ market), have better dynamics, a warmer, more solid low end and more open highs. Because it seems to be a geographical trend, I have always wondered if there a different standard that they use, a la the RIAA EQ curve? |

I've got both the cd & vinyl. The lp excellent. It has more depth & is less fatiguing at loud levels compared to the cd. my concern is that the lp has so much surface noise & there are two strange peep sounds on the left then right side in the beginning of side one that are not on the cd. any ideas of whats going on...

wow, that's the inside scoop! i can see miss handling attribute to the dust, clicks & pops, etc., but the beeps i mentioned sounded like a test tone of some sort. I'd be interested to know how that got in there Ed |
Ed Littman wrote on Tue, 26 July 2005 00:49 |
there's no visual sign of anything wrong, but a better description is that it sounds like a chirp two in a row. it sound like somthing from an electronic device not from damge to the groove. I'm more curious of what it is & how it got there than anything else. Ed |
TotalSonic wrote on Mon, 25 July 2005 21:30 | ||
Damage to stampers or pressings can indeed cause things like brief "chrirps" and aren't necessarily visible. Usually the very outer diameters is where the risk of these types of things are greatest. Of course I can't make a complete judgement without being able to check out the record you have and being able to compare it directly to the tests they approved and the master - but I can assure you that if there were any extraneous "beeps" it would have been picked up on when they made the initial test pressings - which had to undergo approval from the album's producers. Has anyone else here who has picked up the records heard this on the beginning of the A side?? Anyway - sounds like you definitely should get an exchange for better copies. Best regards, Steve Berson |

You really need a microscope to trouble shoot properly. I think what Steve calls "scuffing" I call "non-fill". Under the microscope you can see little bubbles or ragged spots on the top edge of the groove. Usually at the outer diameter of the disk and usually on the outer edge of the groove. It looks whitish to the naked eye. We call marks that happen after the record comes out of the ram scuffs. Either in the transport or the trimmer. |

The unfortunate update from my retaler is as follows..... "Unfortunate news about this album. there will be no replacement availalble. i'm just going to have to refund your order. Apparently there is no way to tell if the original pressings have the error without opening the box set. So, our distributer has returned all of them and will not be offering replacements and there is no word of a new pressing. I apologize for the inconvenience and disappointment." well i've got the cd..... Ed |

I hear a few bursts of microphonic guitar feedback in the intro of the first song on side A. I figure that's not what you're talking about. I listened about ten times at increasing volume levels and I don't hear anything but the guitar feedback (Michell Gyrodec/Dynavector 10x4/Naim NAC72/ATC SCM 20 ASL's) As for the surface noise, my copy is dead quiet. I've seen variation in smoothness (my vocabulary regarding such things is limited) from one LP to the next; I assume this has to do with the preparation (maybe the temp?) of the "biscuit" before it goes in the stamper, but it certainly does affect the noise level. I have one Kristofferson LP released by Columbia where the surface has the texture of an orange. My copy of "In Your Honor" seems really nice. As for the appearance of the package, as mentioned elsewhere, I was very impressed with "In Your Honor". Nicely done packaging. |

I have just purchased both the US vinyl boxset (45rpm) and the UK vinyl boxset (331/3rpm). I noticed on the deadwax of the US version it has Europadisk DMM SB and the number 82876 68038-1, the UK version doesn't have any reference to Europadisk but has the same matrix number. Anybody got any opinions on this! JG |
Mike L Papas wrote on Tue, 28 February 2006 08:48 | ||
Sounds like the UK version was not cut by Europadisk. If it was, I would suspect it would have both "Europadisk" and Steve's initials etched into it. The matrix number is the actual catalogue number which is often the same regardless of country of manufacture. |
