Here is my vintage CD changer (accepts up to 6 CD's). 



I also have the following two CDP's that are less vintage, i.e. less than 10-year old.

NAD S500i



Rega Planet 2000



They are the reasons I have not rushed out to get a SACD player since I absolutely will not buy any run-of-the-mill SACD player.

    Have you ever hit pause and play? The buffer is tiny. It's effectively real time and the player can't go back and read the same passage again. The error correction in a CD player doesn't correct because it can't. 

You seem to think the sentences you typed in have some meaning, which puzzles me.  When you hit pause the unit stops copying data from the buffer to the dac, it stops immediately and the disc transport sits around waiting for something to do.  When you hit play, playback begins instantaneously because the player resumes clocking data out of the buffer and the disc transport resumes its job of topping up the buffer.   That's how my players respond. There is no relationship between the pause/play response and the buffer size.

     That's what you'd expect. I was pointing out that the tiny buffer is what you'd have in a real time system like CD. Whereas on my computer Winamp definitely can be made to react more slowly, demonstrating the greater capacity of the system. I don't know exactly why the larger buffer helps, but it is there. And it does take time to fill. I don't know if it was just cost, or the requirement for quick response that made the CD system necessary.

A hardware FIFO (first in first out buffer) induces absolutely no time delay for filling the buffer when playback starts.  When the first number is loaded, it is instantaneously available to be accessed.  The point is that the disc reader is designed to have a higher read rate than necessary, so keeps the buffer close to full.  Then if there is a problem (a read error occurs and a track must be re-read or restored from redundant information) music is only interrupted if the data can't be read at all and the buffer runs dry.

     You're saying that's how both CD players and CD-ROMs in computers work?

I can't imagine that they could do it any other way.

Guys, can we please stay on topic?  :)

Any and all comments on Vintage CD players are welcome here.

Thats the way my vintage Panasonic portable does it at least, to provide insulation against external shocks.

I still think George should try to track down one of those Marantz CD63 or 67 models, especially the CD63 MKII SE.  I'd love to know how they compare to a modern $200 Yamaha.  If you don't like it you can always put it back on eBay.

Also George, did you know the Sony PlayStation 1 has a cult following as a bitchin' CD player?  Apparently it used some ridiculously good (for the application) Wolfson DAC's or something.

Interesting info. I am on the lookout at work, where we get a handful of used players come in every week.  :)

This is the Sony PS 1, right?

Looks like it.  Here's some reading:  http://www.msnbc.msn.com/id/15484873/

I bought a Philips CD player in 1985 and it still works fine after endless thousands of hours playing (actually it's been in the cupboard for a couple of years but there's nothing wrong with it): big boxy thing.

To quote DavidW, "Coolness."
At $20 including shipping I'll take six of them.

If six of us go in together ;D:

Do you need more than the console?  Are the cables used normal size?

Haha I was only kidding around - I can't believe you found an actual auction for six of them...   ;D

I imagine you need the PlayStation controller too?  However if they are the type that have RCA outs for audio any standard RCA audio cable should suffice.

Was just having an informative discussion with a new friend over at rmcr. Some great info here:
