Here's how it works. Quick speech recording, played against a constant

ratio of direct and reverberant sound changed each time - final one is
reverberant only.

Obviously greatly exaggerated for illustration.

Which is a similar sensation I'd experience when valves are in the
amplification chain. I know (before you start!) that that doesn't
compute. It gives me a very believable notion of instruments (etc) and
spatial perspective.

Not sure what you mean. It's only voltage signals going through the
valves, so what they do to one, they must do to all. So do you mean
that everything sounds a bit further away with valves?


Not really/necessarily.

Music played with valve amplification has depth - that is, some
instruments sound further forward, some further back. When I first
listened to a valve amplifier at home the first thing that came to mind
was 'home cinema'; that sort of 5:1 thing.

Don't know why. No reason why that should happen, I'm sure. But while it
does/I think it does, all's well :-)
