I agree with JP's scoring, but those Watt Puppys were really amazing in certain respects such as bass depth and definition as mentioned perviously. That whole system was really nice but the ATC 50s manage to split the difference between the too cold and detailed Puppys and the too warm and bloated Sonus Fabers.
I am awaiting the return of the Unicorn today, which is very exciting. I think that its introduction into the system will improve dramatically over the EMM Labs direct to ATCs, plus the Doshi phono stage is said to be extraordinary. Will post more pics and thoughts later. Wish me luck on a safe delivery this time...
