Alex Peychev discovered the sacd rot and had a forum which was abuzz with owners that had these decoder boards problems, but he's shut it down.
Since it's introduction SACD has always had many problems, and if it's not with the lasers it was with the horror of the Philips decoder boards with the Mace 2 Furore chip set that had a cancer like bug, that couldn't be fixed, just got worse and worse till the item became a door stop.
This effected many players that used it, Krell, Music Fidelity, Philips.

Then Sony had there own set of problems, it could have been the Philips chipset I'm not sure.
Now I'm not sure what Teac used in their Esoteric models, but it's enough for me to steer clear of any SACD players regardless of manufacturer.
This is a "Wayback Machine" cached page of the now deleted APL find. But this did fix the problem either.

But the many pages of APL forum tech talk about all this is now MIA on the web, CIA stuff from Philips, if you know what I mean.
