I purchased the original Ultralink when it first came out and upgraded to the Utralink 11 HDCD(2200.00) when it became available. I still have the 11 in my system and use it with my studio DAT player and recorder. It was a class A product during its day and still quite competitive with todays DACs in the 1000.00 + price range. It is very versatile with a number of inputs and outputs and 450.00 is a good price. I believe that PS Audio still supports this product but you may want to check with them. My unit has worked without a flaw all these years.
