Professional Burners

This will seem odd but it makes sense to me.

I generally play CD(R) on a cheap Technics/Panasonic SL-PD8 5 disc changer. I take the digital out into an HHB CDR830 burner which has high quality D/A conversion. This arrangement allows me to get great sound from the lowly changer because I am employing the excellent "BURR BROWN" DAC on the HHB (PRO) burner for playback and not the panasonic DAC.

FYI: As my CDR's fail with that RPM related noise on the outer (last) track, I am often able to play them noisefree on a modern DVD player.....take the digital out of it and then reburn onto quality (Taiyo Yuden) media with the HHB.

The panasonic changer has great shuffle options I have never seen in other players be they 1 disc, changer, expensive, or mass market cheap. "Spiral" mode ensures that each random play selection comes from a different disc ie consecutive tunes never originate from the same disc.

The HHB, being a "pro" burner, lets you defeat the SCMS (Serial Copy Management System) which is in force on all consumer burners. More on SCMS later.

Huh? :scratch2:

I don't follow much of this. I'm not aware of any copy protection in CD burners.

Nor do I see a question in the post. Is there a question?
 
Most consumer CD recorders -- actual recorders, not drives meant for a computer -- do have a form of copy protection (SCMS) active on the digital input.

Yeah, I think the terms burner and recorder gets mixed up sometimes.

I'm curious about the "RPM noise" issues, myself. I went around and around with Pioneer and their crappy recorders about ten years ago. They all ended up having issues with distortion being added to some recordings, almost like a distorted echo. Most of the time when it happened it was on one of the last tracks. I assume it is on the recorded disc, and there is no way to get rid of it.
 
aging CDR noise

I will now describe the (RPM) noise which seems to be the first sign of CDR alzheimer's which then leads to "coaster" status.

Recording on cheap media will catch up with you. After a few years and especially if the CDR is not protected from light, deterioration has begun.

The first sign of trouble affects the last tracks on the CDR. It will be an audible noise heard at the rate of disc rotation, similar to the sound of a radial scratch on an LP. This noise is not mechanical; it is definitely coming over the speakers. Unlike the LP, which spins at a constant 33 1/3 RPM, the CD is steadily slowing down as the laser tracks towards the outside of the disc, where the last recorded track is. The LP is tracked outside to inside and the CD is tracked inside to outside. Some portable players have a window so the rotation can be viewed.

Perhaps the light damages the CDR dye on the edge of the disc first, since this is closest to sources of light.

Has anyone else out there heard these noises.....or is the spirit world trying to contact me?......TIM:scratch2:

Interesting thought js; have you tried this? Is the type of marker ink used important? Some claim that certain felt markers are hazardous to CDR, at least on the label side.
 
I'm afraid the green magic marker thing was an urban myth from way back.

If a CD has noise, it's because the player can't read it. Different players have different tolerances. I just get rid of players that are finicky.

It's easy to make ISO images of CDs and DVDs. That's the way the world is going. I think CD players are a waste of time and money.

Music files in the form of computer data files have robust error correction. You can copy them indefinitely without worrying about errors. It's also pretty obvious that the best place for a DAC is on the same machine that has the files. SPDIF, whether optical or coax, is not a robust and error free way to get data from one device to another (without expensive and needlessly complex clock reconstruction circuits).

So if I were in the market for the ideal CD player and copier, I would get a computer and install the best sound card I could find. A shame that sound cards seem to be a relatively neglected technology, at least by high end audio manufacturers.
 
ISO files

I've made a big investment in yesterday's technologies.

My computer, on the other hand was free and is maxxed out at a meagre 512MB of RAM. I've purged it of bloatware and the former owner's vacation photos so it'll function adequately as a surfing vehicle.

So....with only a 40GB hard disc, ISO files for me are off somewhere in the future.

Portable music doesn't interest me......great music deserves my full attention and that means a chair and perhaps a snifter.

Now; how about more input on the "pro" CDR burners......isn't it curious how the gear used by professionals in the music business is so detached from "audiophile" gear. Is this niche marketing at work?
