Teresa Posted September 3, 2016 Share Posted September 3, 2016 Although SACDs pressed at the pressing plant in California (I can't remember the name) had a problem with spindle cracks, that plant shut down or quit pressing SACDs... I found the name of the pressing plant, it was called Crest National. See: Crest National Issues Statement on SACDs With Cracks. The article lists the 7 SACDs titles that were affected. Lucky me, I don't have any of those discs. I have dementia. I save all my posts in a text file I call Forums. I do a search in that file to find out what I said or did in the past. I still love music. Teresa Link to comment
sandyk Posted September 3, 2016 Share Posted September 3, 2016 Teresa I also had problems with the Hybrid SACD "Norah Jones-Come Away With Me" from a plant in the USA. Both copies developed a little split from the outer rim at about the same place. Regards Alex How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area. All that Identical Checksums gives is the possibility of REGENERATING the file to close to that of the original file. PROFILE UPDATED 13-11-2020 Link to comment
sandyk Posted September 3, 2016 Share Posted September 3, 2016 I took a poor quality photo of the faulty Elton John CD, with a bright LED light shining on it from the printing side.

Regards Alex Alex, I just did a google search for "crest spindle cracks" and the thread at SH Forums Norah Jones and *Blue Train* SACD owners: Do your discs have spindle cracks?

AnotherSpin Posted September 3, 2016 Share Posted September 3, 2016 (...) I believe that the problematic mid-1980's pressed CDs that were subject to CD-rot were from the Nimbus CD pressing plant in the UK (they pressed for many UK labels) these are subject to bronzing, and the Polygram Germany CDs you mentioned which are subject to pinholes (...)

kumakuma Posted September 3, 2016 Share Posted September 3, 2016 In the last week or so I have found a couple of CDs that I wish I had backed up to computer.

徐中銳 Posted September 3, 2016 Share Posted September 3, 2016 Oh boy! the cables are touching each other in that picture...remove all the greatness recorded in that music... so much money wasted for an error like that :-) [ATTACH=CONFIG]28853[/ATTACH] So, photo from that day's amplifier terminals end : He was bi-wiring and bi-amping. Of touching, what of speaker cables such as : Perhaps he's most careful when testing for a screw : « Q : I hear that you work overtime quite a bit. A : Yes, sometimes, I have to conduct listening tests to determine a single screw that will be used in a chassis. Q : A single screw ‽ A : Yes, a single screw. And before I even listen to anything, I have to set up the speakers and amplifiers, warm them up, and so on. When I need to change my monitoring equipment, it involves moving about a ton of equipment. Sometimes, I have to change the listening environment also. It also takes time to prepare mentally. The reason I work so much overtime is that it's quieter during the night or on weekends and holidays when no one is around, and the power is cleaner too. When I have to listen to a screw, it is quite a consuming task, so it's usually done late at night or on weekends. It's actually quite risky to start a listening test from 5 PM, towards the end of the workday. Everyone doesn't leave at the same time, so the sound changes every 5 to 10 minutes as equipment is turned off. So, it's quite risky to attempt a proper listening test around this time. » « an accurate picture Sono pessimista con l'intelligenza, ma ottimista per la volontà. severe loudspeaker alignment » Link to comment

You really can't help yourself with the snide comments can you ? Only my most played CDs have been ripped to internal storage due to the expense of large capacity SSDs. Despite what you and your know-it-all buddies may wish to believe, a flac copy on an external HDD is a poor substitute for a well recorded and mastered CD ! Several members have also remarked recently about the differences between much older and freshly ripped CDs, as computers and their Operating Systems and hardware have improved in recent years. I went to the trouble of posting that photo for the benefit of others so that they can check their most treasured CDs, and hopefully back them up before they are lost forever. I don't think that others I have lost previously due to this problem were all from W.Germany either.

That's absolute BS! You have followed me around like a bad smell for years , and just can't help yourself with the personal attacks. Like many other members, I have CDs from the initial batch of CD releases and earlier years, that haven't been played for many years, and are unlikely to be played again.

I didn't say that direct CD play was better. I obtain far greater SQ from properly extracted tracks to a PC than most affordable CD players. What I am saying is that most people aren't able to extract, save AND export the highest possible SQ from well recorded CDs due to the high level of internally generated RF/EMI as well as interaction through the PSU area .

It's OK, it really is There is no need to go hunting/searching for someone who does all three things I mentioned because someone doing even one of them is all the madness I need to see. And in that case, there's no need to look any further than you as the perfect example Maybe someday you will grasp the concept of data transmission and duplication and look back at your theories today and smile but I won't be holding my breath on that one.

Indeed... I do wonder though if the ISP routers/switches in between point A & B are using the proper audiophile firmware version for their hardware so no bits are lost or added in transit In SandyK's world, there are such a things as 0.25,0.50 & 0.75 values in the normal 1' & 0's scale the rest of the binary world follows My Audio System -Last Updated May 20 2021 Link to comment
