I have been thinking about the gain structure of pre and power for a home theater amp or stereo amp with pre section being solidstate and tube
consider a tube pre with gain of 20 and power amplifier with gain of 20 log 33 or 30.37 db so how much this ratio needs to be where in tube pre I cannot change the gain but can change the gain of the power amp. I do understand the total gain ratio but what is the usual case i feel even amplifier with 26db is quite high if we have a tube pre with 20 gain
Another scenario with solid state pre with 6db gain and power amp at 30db gain so what is to be taken into consideration
For HT application
For Stereo application
Now do commercial HT amps comes with pre gain stage inbult? as the AV processor or receivers dont have a proper standard some give 1Vrms out and some are capable 3.5Vrms out
Can anyone please provide few inputs on this
