Better sound. Try it sometime. Then you'll know.
OK, I'm sensing a challenge here, similar to Danger Dave's assertions that
resulted in the ³Power Amplifier Without Power Transformer². The problem is
that with respect to Danger Dave's assertions, SNR was an easy to measure
parameter. Unfortunately your claims for the benefits of using a cathode
follower to buffer the IFT from the detector diode, is ³Better sound², a sort of
vague standard.
Before I take up my soldering iron to demonstrate that an AM detector the equal
of yours can be built without the cathode follower between the IFT and detector
diode, I will need to know how to measure ³Better sound². Can you suggest some
valid objective measurements I can use to measure ³Better sound²?

Now John, there are dreamers & there are doers. Which are you?
Pls pick up that soldering iron & show us what you can do.
Cheers to all, John L Stewart who still remembers which end is the handle!
