I have an early Wadia 6 I bought 10 years ago. Never any problems. Always used bal connectors direct to the amp. It really does sound best this way. I also have a Wadia 830, which functions very much like the 6 , except that it has the internal dip switches to adjust output to match amp/speaker combinations. The 830 has updated Wadia tehnology and sounds a bit more "open" than the 6, but they are definitely cousins. I'm selling my 830, keeping the 6, in order to give priority to speaker replacement.
