Default DBT a flawed method for evaluating Hi-Fi ?

Someone else, in the cap testing thread, pointed out thatone might be more
likely to detect a difference between caps in an amp with a low parts count.
That's why the µ-follower stage seemed such a good idea.


Yes that was me. You can get the same quote from several different sources,
e.g. Eric Kingsbury "With very simple circuits like this, the quality of all
the active and passive parts is critical. Indifferent capacitors, resistors,
and even switches, wire, solder, will be audible" with reference to his 6V6
(trioded) PP amp. reference:

Hello Andy.

Yes. I realised it was you, but I did not mention your name
as you had not posted much in the cap testing thread, and I
thought perhaps you wanted to keep a low profile:-)

I am grateful to you for your suggestion, which has been
endorsed by many others. Without it, I would have built two
complete channels of power amplifier, plus psu units, many
many more times the number of components.

The test µ-follower is to be built by my BBC pal, to a circuit
drawn by another ex BBC engineer, Morgan Jones.

Iain

Hello Iain

I have killfiled a small number of people who post on this forum, so I don't
partake in the usual ng sport of endless ridiculous mud slinging. I keep the
profile that befits the subject, and since this is one of the emptiest
newsgroups on audio subjects, that means not many posts.

Ah, Morgan! Good to see you're keeping him off the streets. Andy

It seems a little better of late. Only one Anglo Saxon expletive in my
direction
this year - today in fact:-) New Years resolutions?

Understood. I can see from a little archive research that many people
seem to have dropped out from this group. I think I can see why:-((

It would be refreshing to see him on this NG.
But little chance I fear:-(

Makes me think of Groucho Marx "I refuse to belong to any such club as would
accept myself as a member"......
