Just wondering...

Nelson how do you make a good sounding amp? The designs you have on first watt are quite varied so it must be hard to follow a general formula you have to create a good amp? You don't go for high power or low distortion. Do you just start playing around with circuits to see how they sound? Does high bias and FETs work for you?

Good ears may be? Some don't have it but believe in it and make use of a panel of good ears. Some don't have it and think that Aleph and gainclone sounds the same

You should try "Zen Pot"

Members in the other thread are talking about it all the time

Go here: Technical Articles

When you get to the top, rince and repeat

Read every one of the pdfs starting at the bottom. One of my favorites is "Audio, Distortion and Feedback".

Making amplifiers is all I do, and after 40 years I seem to have gotten good at it.

There are still a too small selection of finished devices both as integrated amplifier and power amplifier - particularly in the power area between 0,5 watts and 10 watts output power at 8 ohms.
Here examples - currently available - made in Germany:
valvet - just pure music
Audioprojekte - a sense of music
Home André Buscher Audiotechnik - André Buscher Audiotechnik - Puristische Eintaktverstärker (without envelope resp. enclosure, but include power supply - based on a SRPP approach - similar to Aleph with dynamic CCS).
more URLs:
URL Collection of Commercial Single Ended Integrated and Power Amplifier Devices
NP's first Single-Ended Class A amplifier using BjT's biased by a CCS

For the aim of diy it seems to be, that there are infinite number of concepts and approaches - go to
URL collection of Single Ended Solid State Output Stages
