You also seem to have only done this a few times, not many times to

We didn't worry about setting up a blind test at this stage, as my
concern was simply to find out whether there was a difference,
perceived, psychological, whatever.

From my point of view I'm satisfied with the results.

That would be fine for you - if you had not then posted your opinions here
as if your 'test' had any reliability or value for anyone else. :-)

Alas, since your 'test' was not conducted in an appropriate manner, your
report will be unlikely to have eithe 'satisfied' or been of any use to
anyone else.

Quick question - in the event of a lightning strike, what would you
rather have fried? £8 worth of surge protected mains distribution block,
or £1,000 worth of amplifier?

Bit of a no-brainer really, that one.

Indeed. :-) Particulary since a lightning strike may well crisp the
'surge protection' *and* the rest of the equipment locally connected. I'm
afraid that a small VDR isn't likely to be able to absorb the energy of a
nearby lightning strike. :-)

Nor is a VDR likely to be much use against RF spikes as it laregly converts
a voltage spike into a current pulse. So may still allow 'clicks' though if
the units you wish to 'protect' don't have decen PSU, grounding, etc.

If you wish to avoid clicks and pops from audio gear, then go for decent
kit, and perhaps suppliment it with *filters*, not a 'surge protection'
unit.

Slainte,

Jim
