If your power amp requires 2V for rated power, (ie: 2V output)- then at normal listening levels (average level of around 75db) - your amp will need 0.5W to achieve that level - that would be around -26db or an output from the pre of around 0.1V for a 200W amp
Sticking with that 200W amp, raising the input to 0.7V - we get output power of 4W - average listening level would now be somewhere around 87db (@ 3m)
So at a very loud listening level, we enter the optimal Zone for distortion and Noise - 0.9W gets us around 6W and 89db
To me that sounds pretty damn good...
When things get loud - there is lots of music signal which will cover up noise and THD
At normal listening levels, the pre gets it optimal SINAD readings - which is exactly where you want them to be!
I really fail to understand why people consider this a negative?!
At which point in the output level chart would you want the optimal SINAD ? at which listening levels would the SINAD be most audible?
This seems like a very sensible / logical design choice!
