Unconventional Audio Frequency Amplifier

I think you will be interested to see the contribution to the amplification of all cascades. I used the Qspice option.

I understand that it has a high frequency response and this is ok, for me that is not so important because I had 50 KHz uper limit and I liked it. I noticed you are biasing the transistor verry hard and this helps for good frequency response, I am not pushing my designs like this because my ear tells me when I have 1K-Ohm per volt sounds amazing. There is a fan base for what you aim but I am more vintage.
