Input voltage gain on levinson amps ?

Dear Alwyn: As important as is the input sensitivity and voltage gain there is ( at least 9 one critical subject that your friend has to take in count: both amplifiers sound diferent, its quality performance is diferent and not closer each other, so your friend could experiment a sound that is far from be : natural well tone balanced. The 20.6s ( that I own ) are in a diferent audio league than the 29 ( that I know very well ).

Now, like Arthur say: he can try it anyway.

regards and enjoy the music.
