First being that it is quite difficult to get a grip on the quantities to measure. the current set of measurements does show SS with better numbers. I have heard many nice SE amps and don't appreciate their performance. I like PP. Not the traditional, but Class A, and built like the amps which gave SE their reputation as 'best'. HD power supply design, choke input filters, excellent parts...

For an amp, adding loop NFB improves the quantities which are measurable...but the amp does not sound the same anymore. Generally it sounds worse. This contradiction leads me to believe that the measurements which show SS as better just aren't the whole story.

My PP amps have a lot of NFB, it is short path, plate-to-grid through a circuit called E-Linear. It works quite well IMO. low output z, good freq. response...

!

Are we sure it is the mic or the equipment after the mic? The reason I mention this is because the recording equipment I have seen thus far is far from SET or even PP quality. Usually poor quality SS designs and the ICs are very poor too.

Just a thought.
Take care buddy.

Howdy John, good to see you in these parts
