Yeah, but 'exactly the same way' means that they have to have the same

Yup.

Ok, so now you agreed that driving the same voltage on the speaker
terminals will cause the speaker to move the same way, given that the amps
PSU is up to it, then:

1) Explain why a SS amp could not drive the voltages in the same way as a
valve one


Forgetting that little magic word, are we??


2) At what point do you declare differences to be inaudible?


Out on the back step - all the way indoors, up to the patio door, I can tell
without any problem. Once outside, it starts to become less obvious -
specially if I'm cutting the grass (petrol mower).....


equipment exists that can measure down to about -140dB - are you
suggesting the 'valve sound' comes from sub -140dB artifcats ?


We're bird-feeders - I see any artifcats round here they get an apple (when
available or handful of peanuts, if not) chucked at them!


perhaps this is why speaker wire makes a difference - maybe they were
right after all!



OK, enough ****ing about.

Ian, it's no big deal - you either *get* valves or you don't. Not everybody
does, so don't bash yer brains out. It's not easy to describe the
'difference' without resorting to subjective phrases like 'space', air',
'texture', 'vitality', 'musicality' or whatever. These phrases immediately
draw a (usually hostile) reaction from the unbelievers and the strange
phenomenon of valves and SS becoming antagonistic and mutually exclusive
starts to appear. (A load of ********, given that I've had an SS amp driven
by valve pre's on the go today! - See

http://www.apah69.dsl.pipex.com/keit...w/sharkey1.MOV

for a ****e little movie of this in action! :-)

Also the 'science' involved is a) mostly way over my head and b) not clearly
agreed on by any significany majority of the theorists. All I can say is if
you haven't spent any time with a valve amp yourself, get a good listen and
see if it does anything for you.

Knowing this don't happen on every street corner, I often say people I
*know* on this group are welcome to come and hear mine (and take the ****,
if that's what they want) if it's doable. (I'm in Cambridgeshire right on
the A1, where are you? - Cornwall, I expect, given your predilection for
dragons!)
