For Skylab Jan has provided a couple years ago following info about the maximum output of Classic:
- At 600 Ohm: 160 mW / channel
- At 300 Ohm: 320 mW / channel
- At 50 Ohm: 1.9 W / channel
- At 30 Ohm: 3.2 W / channel
Jan suspected that "CORDA amplifiers do not produce a WOW-effect". I am not sure this is true. When you at first time hear a neutral sounding good quality equipment like the Classic, it is possible that they do not give you an immediate WOW -feeling, especially if you have been accustomed to hear equipments exaggerating bass and dynamic. But if you have enough patience and keep on listening to them, after a while you start to hear details and nuances in the music you have not heard before. At this point come the WOW -feelings and they continue to keep on coming after that.
These are the figures I was referring to - would the output of the Concerto be similar?
