How Well Shall a CD Transport "Track" a CD?
fiogf49gjkf0d
A while back (I thought) I was having trouble with my Accustic Arts Drive 1 CD transport. It was skipping and messing up on CDs I wanted to hear. Since I normally listen to LPs, it took me a while to dedicate the time and pay attention to exactly how the transport was messing up. It turned out that some CDs worked OK, and some did not.  Then I remembered that the CDs that were not working now on the AA transport had all been dragged by me out to the car and used there in the car CD player. When I carefully cleaned the problem CDs, most of the problems with the AA transport went away, but some of the messed-up CDs still would not play well on the AA transport. They all played "fine" in the car.  Now my question is, why will the "crappy" car CD player "track" dirty CDs "better" than the Accustic Arts Drive 1?

Add this to the pile of the Mysteries of Hi-Fi.

Reflectivity is a real issue

Some drives do not get along with certain reflective surfaces. I had a Philips that played just about everything. Then I bought a Yamaha and all of the "gold" colored CDs would not play. I think that your dirt issue is not the real problem. If the CD was made on a writer instead of from a stamp, it could be the brand of the blank.

Color? Brands?
fiogf49gjkf0d
Hmmm...  The AA uses Philips Pro 2 mechanical guts. Most of the discs that would not play played fine after I cleaned them. Various cheapo CDs my brother burned for me over many years played fine, and one RVG (Rudy van Gelder) jazz CD would not play at all after cleaning (and I think it played OK before I cleaned it!).  I played silver and gold, and maybe a couple of other colors; I'll have to check that more systematically.  That car is pretty old, so who knows what other grief it inflicted on any CDs it played.  Still, it continues to play the damn discs! At least I think so. Remember, I still haven't bothered to set this up rigorously, with controls...

Plextor PX-891SAF.

I always had very luck with Plextor CD/DVD drives (sound-wise) but they had disappeared of the PC market, but seem to come back now:

I would buy one now but I need to import it and there are a big mess going on my country customs services now, and it would take a while to normalize.

Cheers!
