Inspired by?
Hugh, I have seen some where, long time ago your inspiration for building a better sounding amplifier came from listening to a specific NAD amplifier, that possibly had something special, that you probably wanted to investigate. Is it correct, and what did you find good about this NAD amplifer, and which NAD model was it?
one of my amplifier sets are the 20 year old, cheap cheap! 1240Pre / 2240Power, and I actually like to listen to that also today, they are so easy to listen to, even though there could be more detail. Very musical, and a lot of grip in the bas, even with only 40W (powerenvelope!!)

Thanks for your post, good question!
My original inspiration for a good power amplifier came to me in 1969 in the room of an undergrad elec engineer friend who had built the 1969 JLH in a shoebox.

We played Paul Desmond's 'Summertime' LP and I was bowled over by the musical presentation, and Peter's conviction that transistors could be made to sound as good as tubes.

That was a very long time ago. Since then inspirations have been Mullard tube circuits, particularly the EL84 PP tube amp from the early sixties, Jean Hiraga's Le Monstre amp, Tomlinson Holman's brilliant 1972 phono amp for the NAD 3020, and a variety of lesser designs since then. The FetZilla, incidentally, has many JLH influences in it, the original topology was from Lineup, we must not forget, with voicing by Greg Peters, from Queensland, a northern state in Australia.

It is extremely difficult to be original in this game; everyone copies everyone else, and extracts ideas from all over the world. I claim no originality in anything I do, although the implementation does have flashes of creativity in it. The fact is, the harder you work to reduce THD, the more you run the risk of throwing musicality out the window. To me, this is throwing the baby out with the bath water.
