I have two. One is installed via toslink in from a cable box to spdif out to a Bel Canto Dac 2.5 to Bel Canto M1000 AND a Bel Canto C5i. This primarily drives indoor TV sound but also indoor/outdoor audio. Initially I bought to drive two devices with the same signal, but really liked the improved sound. I bought the power supply and it was a huge upgrade again. I liked it so much, I installed another in a second system via toslink out from TV to a Creek 100A with Ruby DAC. Nice improvement again compared to not using one at all. I think many newer DACs perform better when receiving a 96k feed, and this does that really well. I recommend getting the OTL option if your dac has a transformer on the input. Also, highly recommend the Dynamo power supply if you are using this with a higher end system, although it does double the price. Finally, his BNC cables are very good too.
