Its funny you mention this Cal MASTER SERIES SC-TEN Tube Dac. Someone just sold this Dac on Ebay last month. I still have the ad. I rarely have seen this Cal dac being sold. You can email the guy who sold it, also you can email the guy who bought the dac. There's also a pic of the dac. The guy was using the Cal on a Sony SACD player. Here's the ad. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3813587293
