preamp gain in relation to whole systems help


hi guys

newbie question, what the gain in preamp effect the whole systems?

while minimal volume is at 7 o'clock,
i run preamp gain of 2 with 100w amp = listening volume at 11 o'clock, then

i run preamp gain of 8 with 100w amp = listening volume at 8 o'clock

then whats the use of high gain preamp if its only limit the volume tuning?

whats the the different between the gain 2 and 8 preamp driving 100w power amp? will they effect the final watt? my understanding is they stay the same. enlightenment please

i am planning to try out class A amp. will this high gain preamp help? i also see some preamp with gain of 12.

Hi Al

i am not sure bout gain stuff as well. maybe its 2^(2-1)=2db and 2^(8-1)=64db? can someone correct me if i am wrong.

how bout using 24 stepped attenuator and alter the resistors? say use 100 stepped calculation for 100k pot but only use the first 24 steps? will this help with the volume adjustment? thx for the helps
