Philips SACD 963; upsampling in general

Dear friends,

About a year ago I snapped up the Philips SACD 963, partly because of its upsampling capability — it will upsample a standard Red Book CD to 96KHz or 192 KHz. In my experience with the player, this does add extra presence and depth to the sound. I'm very pleased. But there's always a snag somewhere, isn't there?

In this case, it's the playback of CD-Rs (recorded on a separate CD player and component CD burner, not a computer). Yes, the upsampling seems to work just dandy with CD-Rs, too … but (usually beginning several tracks into the disc) there are randomly timed popping sounds, not particularly loud but very distinct and annoying enough so that I have given up listening to CD-Rs through this player.

What's up with that?

I have been so impressed with the upsampling phenomenon that I have considered relegating the 963 to DVDs, SACDs and factory-made CDs, while getting a separate upsampling unit — either for my other system or to use in lieu of the 963's upsampling circuitry if that's where the popping originates.

But there appear to no longer be ads or articles about upsampling components. A few years ago I thought they were a serious rival to SACD and DVD-A and might well be more cost-effective if they came down in price from the $1200 Musical Fidelity pegged theirs at. But upsampling units no longer seem to be offered. Was this a good idea that flopped because manufacturers dropped the ball in marketing it?

I highly doubt that the upsampling has anything to do with pops in the CD-R.

Most likely the problem is just that the laser has a hard time accurately tracking the cd-r because cd-r is alot less reflective than a factory pressed cd. It may also have to do with the blanks you are using. No cd burner is perfectly compatable with all cd-r or cd-rw. Computer burners have 'write strategies' stored in the firmware with supposedly optimal parameters for buring a particular disc. They get the information about what type of disc it is by reading the ATIP section of the disc (Absolute Time in Pre-Groove). I don't know if standalone burners employ similar strategies, but even if it does it may not have been tested with your particular blanks. Then there is the possibility that the blanks are just not high quality to begin with. You might want to try a few different brands.

MDS -- Thanks for your reply!

I've tried three different brands of CD-Rs, including Maxell and Memorex, but I'll keep experimenting.

Some preamps now do this for you. I have an Outlaw 990 which upsamples to 192khz from anything lower. I'd guess some of the newer receivers do as well.
