sorry for three posts in a row but I missed this earlier.
Prez, I couldn't figure where the 26dB cam from but now I do. My earlier analysis was of the VK-75/150 and I did not know you were looking at the solid state amps.
If you take a look at BATs website and look at the following products: VK-255SE and VK-600. You will see that both amplifiers have 26dB of gain. Yet one is rated at 150W into 8ohms and the other is 300W into 8ohms.
The practical difference between these two amps is that the VK-600 is basically a chasis with two of the smaller amps fit inside. There are other differences but practically speaking, this is the crux of it.
Bottom line. I totally agree that paralleling identical amps does NOT change the gain (dBW) one bit. But clearly, BAT is a good example of how it does double the output power.
I believe you should see now that your conclusion is incorrect. The 26dB, as stated by Al just means the input voltage gets multiplied by 20 for both amps.
To get 150W@8ohms from the smaller one takes about 1.7 volts in.
1.7V times 20 = 34V......34V squared divided by 8 = 150W
If you drive it harder you can't get more than 34V because the voltage can go no higher and it clips.
To get 300 Watts from the bigger amp takes about 2.5V in which produces about 50V out. It can go higher because the voltage rails are higher. It has a power supply with higher voltage rails and presumably more output devices in parallel to share the higher amount of current it can produce. It's not higher power because it has more devices in parallel, it is higher power because it has higher rails. It is not simply 2 of the smaller ones in the same box.
You clearly don't have a firm grip on the basics yet you attack me for pointing that out. I don't know what to tell you. That's all basic electronics that a first year tech school student learns yet you call me a complete and utter fool when I explain it to you.
