Analogue Productions SACDs

Good answwrs...

I have 5 different Analog Productions SACD’s and each has a CD layer, a 2ch SACD layer and the 5.1 surround SACD layer.

Thanks very much for your answers!  I'll order one and find out!  KB

Here is a different question on SACD: I have loved the format from the first time I heard it, many years ago. I own two Sony SACD players that were $3000 retail, as I recall, when I acquired them--also many years ago. They are the XA777ES and the XA9000ES. The 777 has been a fantastic workhorse, with thousands of hours on it. The 9000 has been an infrequently used player is a second system. But neither will now play the SACD layer on hybrid CD's. I have read very little on this amazing anomaly of the SACD format. Does anyone have any insight on this issue? TC1

I asked Microsoft Copilot again and this is what it said:

Hybrid SACDs contain two layers:

• CD layer: Read using a red laser at 780 nm (same as standard CD players).

• SACD layer: Read using an infrared laser at 650 nm (similar to DVD technology).

🔬 Laser Configurations

• Dual-laser systems: Some high-end SACD players (like Sony’s SCD-1 or SCD-777ES) have physically separate laser assemblies for CD and SACD layers. This allows for optimized reading of each format.

• Single-laser with dual wavelength: Many modern or budget SACD players use a single optical pickup that can switch between wavelengths to read both layers. This is more cost-effective but can be less precise or more prone to wear over time.

⚠️ Common Issues

• SACD layer failures are often due to laser degradation or misalignment. Players may still read CDs fine but struggle with SACDs, especially hybrid discs.

• Some users have had success recalibrating the laser or adjusting internal pots, but this is risky and not recommended unless you’re experienced with electronics3.

If you’re evaluating a player or troubleshooting one, knowing whether it uses separate lasers can help diagnose issues or justify a repair. Want help identifying the laser setup in a specific model?

Tom again:  Finding laser assemblies for older (and sometimes newer) vintage CD and SACD players is a major flaw with these players.  It shouldn't be too hard to find someone who works on Sonys and find out if your SACD laser can be replaced or recalibrated.
