Groundhog Day. . . .

Has anyone noticed that, when a disc is playing and you press previous or next on the cd player to select a particular track, the sound is inferior than if you press stop then press previous or next to select the track and then play?

Try it, its bizarre. To my ears, there is a marked deteriation in sound quality when you attempt to play the track selected without going to stop first. Furthermore, if you press play on the remote control rather than use the play button on the cd player itself, again the sound suffers. Anyone got any ideas on this?

Enjoy the music,

Also, have you noticed that when playing a record that if you place the stylus on the disk then start the turntable it sounds radically different than if you lower the stylus whilst the platter is turning?

This is easy.

You must approach your local friendly dealer with your problem. Make sure that if you’ve been drinking the night before it was Vodka, not Whiskey and that you have a gum shield in place.

You need to ask him to conduct ten 20 semi-random tests of 30 seconds each: 10 with direct track selection after stopping, and 10 by playing a bit of track #1 muted, then paused, followed by jumping to track #4 using the Next button. You MUST have your eyes closed for each test otherwise it is invalid. Your job will be to guess whether each sample is better than the original benchmark or the same. Of the 20 trials, you must ‘guess’ right 17 times to confirm that there is a difference.

Some may suggest that if you are having a problem with the front panel selector v the remote, that you should try new batteries. Well, I’ve tried TDK, Duracel, EverReady and AOM (Asda’s Own Make). Surprisingly, in a blind test conducted over ten 20 CD’s played at EXACTLY the same time of day, I found no difference at all.

My gut feeling is that either your CDP has a defect and should be sent to Naim for an immediate service, or that your CDP has a defect and should be sent to Naim for an immediate service.

Hockman

You didn't do the edit in time.

Hockman can't help it . He just read the Novotel report thread and saw that the NAP 500 can make Wynton Marsalis foot tapping, exciting and real. Poor old Hock obviously bought a defective one.

I have never checked this, but seem to remember it's entirely normal for Naim players to exhibit this phenomenon. No need for a service.

I'm sure there's been lengthy and learned discussion of the reasons why but I don't remember

Has anyone noticed that when you play a CD upside down it sounds distinctly quieter? You may have to try it a few times to convince yourself there's a difference but single-blind listening tests have shown that 15 out of 20 times I could tell which side was up.

In case anyone is interested, the music used was 3:33 - the single edit of 4:33.

I tried the same thing with a Wagner LP on my turntable but found it impossible to tell the difference.

The experiment was conducted using 33 1/3 rpm, starting up the turntable with the needle on the platter in both cases - as recommended by Tony.

Have you noticed that when playing a CD if you press the "next" button the music sounds different?

This is not in any way scientific because if you are playing a Celine Dion CD pressing "next" makes no difference to the sound at all.

cheers

Pressing stop works bloody wonders.
