About a year ago I took a leap and bought the DCS Rossini and clock after reading many many reviews and thinking long and hard. My first evening listening all I could think is guys have no idea what they are missing. I've tried many sub 10K DACs etc... and have had a lot of gear for a lot of years but this thing really rocked my world. Yeah it's a ton of money but for me it's worth it, it exceeded my expectations. I don't think you need the clock just the DAC is good enough. The clock makes it better but I didn't even hook up the clock for a while and just listened to the DAC and wow what a great piece of gear. After using for a year it's just been totally solid not a gitch or hiccup such a well built piece of machinery. Guys hate on this expensive stuff and say we are dumb braggers just for buying it. It's a shame we can't all have one because after many years of upgrading and trying tons of stuff I still had a lot of room left to be surprised by something.
