SY, I tried to read that book. The first few pages were OK, then my eyes just glazed over.

Seems like I need to learn a whole lot of stuff I don't care to know, just to find out a few things I do want to know. I have neither the time nor aptitude to do so.

Glad I chose to sample the PDF first.

It may be worse than that. You may need to learn a lot of stuff in order to understand what it is you want to know. Without that, you can ask a question and we can give an answer but no useful information will have been transferred.

Life/the universe/everything is like that. In order to understand the answer, first you have to understand the question.

I would suggest that you persevere. Don't expect to become an audio expert in an hour. It has taken me 45 years of electronics to get to my current understanding, and I am still learning.
 
Thanks for the tip, boywonder.

DF96, I appreciate the encouragement, however I think you may be overestimating my ability and my desire. Statistically, I only have about 30 years left and there are many other things I hope to achieve which take precedence over becoming an audio expert.

I will give Mr. Rosenblit's book a try and if that also overwhelms me, then I will stick to minor amp tweaks like cap swapping, tube rolling, upgrading transformers, etc.
