I recently bought a vintage NAD 5200 CD player. Beautiful machine, simple controls. But .... it doesn't read everything. I have several hundred CDs - everything from old "unremastered" to enhanced (i.e., with embedded interactive software or Quicktime movies) to hybrid SACDs to HDCDs, etc. - in other words, just about every kind.

The NAD reads probably 75% of my collection but doesn't consistently read many (but some of them sometimes), especially the enhanced CDs. No problem with most of the HDCDs and (surprisingly) hybrid SACDs, although some won't read.

Anyone else have this problem? The NAD 5200 is one of the earliest players (1983, I think?). I respect that CDs in 1983 were probably relatively simple in content (as well as few and far between!) and that the old machines were designed to play the discs of those days. I'm just wondering if anyone else has had this problem, and if there's anything that can be done to expand the list, so to speak, of CDs that will play.

I should add that the discs the NAD does play sound really good in my system.

When was the laser head last cleaned or replaced? The intermittent or inconsistent reading of various discs points mainly to a weak or dirty laser assembly.

According to the seller, very recently, and by a very competent technician.

I had a NAD 5440 that had the same issue, mainly concerning HDCD encoded discs. The unit was stolen during a B&E and I managed to work through my insurance to replace it with a Micromega and never had that issue again. Good player, the NAD, but limited to standard CD's.

Samey same. My old NAD was very fussy with anything but plain ol' CDs. Replaced it with a Pioneer laserdisc player for CD playback, which seems to read every type of CD I throw at it.

Early CD players were designed to play CDs without defects. Later on, designers had learned and designed players that specifically did play discs with defects. One thing to watch out for are discs you burn yourself. Don't use them in these old machines. The head can be run back into the end stop (outer edge), then tear the teeth out of the gears. This is true, and we processed many warranty claims for this type of damage.

Depending on how early a machine this is, the alignment procedure is quite involved and requires special discs and tools, plus filter jigs. I built many during the early - mid years of the CD player. So your CD tech will be an older fella for sure. If he's a young fella, he may fall short as an experienced CD technician. We went through trials and horrors during those years. I think they left a mark!
