What is the point of expensive CD players?

I know what a CD-ROM drive at full blast sounds like. However even the
cheapest ones now have quiet or silent modes; they don't all have to run
at top speed all the time.

Then the extra speed to read a dodgy CD rather pointless?

I don't follow why it might be pointless.

Because I'd have it on silent all the time. If a high speed device was
needed to read a faulty CD (that presumably can't be replaced) I'd use my
PC to rip it then copy. But then I've never bought a commercial CD that
won't work in an ordinary CD player anyway.

OK, but I think that's describing a different case - a player with high
capacity storage, rather than one with a RAM buffer.

Depends a bit on the speed in question. Running at, say, x4 speed should be
enough to allow a re-read or few given a buffer. But CDROM drives in
computers and ripping software may tend to try and read at far higher
speeds because they (I guess) take for granted that the user wants to rip a
disc ASAP.

At some point this extra speed becomes counter-productive - either leads to
so many more read errors requiring re-reads that the rate of reliable info
extraction maxes (or falls), or means loads of mechanical noise, or both.

I've one or two discs that none of my audio players will read, but a CDROM
drive will. Also one or two that reverse this quirk. Rare, but happens.
I've also some discs that work in one player but not another. Bit more
common, but again, rare. Difficult to know why in the absence of some
suitable test equipment.

I've still got some gatefold LPs. They've been digitised, and the
recording cleaned up - but there's a lot to be said for a 24"x12" image...

Quite a lot of computer drives will slow down as they run retries, which
tends to indicate reading does get easier at low speed.

One of my CDs I found in a hedge. It plays perfectly.

The only time I've had a dodgy one was some sort of pressing problem.
The manufacturer sent me a replacement disc, and I sent them back the
old disc with a report from the CD tester we had at work. It wasn't a
speck of dust, it was all over it, and I assume they had lots.

Not surprised. Often I can see no difference between discs that play fine
and the few that won't.

I returned a number of discs that had the 'brown rot' problem that PDO
created for a while. The replacements were all fine. But as previously
said, I also have various other discs that show problems. They are rare,
but crop up. Again, often with no eyeball detectable reasons.

Much lower levels of problems that I got with LPs back in the 1970s,
though!... :-)
