JA - thanks for the tip. I won't be pursuing it. Bill Thalmann tuned up the old Thiel SCD-1 which had been previously upgraded. It's quite a piece of gear. The SACD head was not salvageable, but I have very little SACD hard media. I'm beginning my investigation into software storage and playback of high resolution media, while avoiding 'normal' computer circuitry. I auditioned iFi's Zen streamer - pretty impressive for the price.
