those which were *not* direct heated.

I would suspect that the change was done entirely in terms of
convenience, rather than sound quality.

Which, correct or not, would be consistent with what I wrote, and which
you quote above. However, either way, what we 'suspect' isn't actually
evidence w.r.t. your assertions about the 'sound' of such valves. Your
statements continue to have the status of an assertion of belief on
you part for which you have offered no evidence.


The sound quality was no doubt considered "close enough not to make a
difference". And this is the issue really - when even small changes in
sound quality do make a difference, then builders will use what they
empirically find to be better. No doubt nothing except a few volumes of
statistics will have any effect on your judgement,

It is a shame that you seem not to understand the distinction between a
dismissive phrase like "a few volumes of statistics" and the value of
reliable and relevant evidence, rather that an assertion of faith.

Please note that I have not asserted that direct heating does not, or
cannot have any effect. What I did was ask you to provide some evidence for
your assertions that it does. You have provided no evidence.

so it's pointless pursuing this, particularly since you admit you know
virtually nothing about DHTs.

....and you seem unable to tell us much more than "virtually nothing" about
them - at least in terms of useful evidence rather than your personal
faith. :-)

Hence I'd agree that trying to pursue this with you would be pointless. I
feared this might be so, but was curious for the reasons I gave, so
wondered if you could provide some useful information. Alas, not.

However the exchange has served the useful purpose of illuminating that you
seem unable to offer any evidence to support your personal beliefs. In that
way, I think it has made a useful point which the OP and others can take
into account if they so choose.

Slainte,
