My problem may seem rather strange, but here it is:-
The interesting thing is that whenever I connect a new piece of
equipment, using the Lapis cables, the same thing happens. Fantastic
sound for a few days, in respect of all components, which then fades
away. It even happens when there is a change to the cables. For example,
I have used Pro Gold to clean the connections from time to time, and on
occasions, the original sound comes back, but again only for a few days.
This happened most recently when I had the phono plugs on a pair of the
Lapis cables resoldered as they had become loose: great sound for a few
days only.
My own suspicion is that there is some kind of impedance alteration
going on and that a new/cleaned/repaired cable, or new piece of
equipment interface in a particular way for a short period before
changing, but I could be completely wrong.
The only things that occur to me a
1) Connections are tarnishing in some way. This really should not happen so
swiftly, or be so noticable, though. Hence it impies something odd is
happening.
2) Despite what you say below, the effect is due to your perceptions
responding to an expectation of change, or some 'uncontrolled' effect -
e.g. slight change in volume or listening position - that you aren't
noticing as a factor.
May be something else, of course... :-)
What I am sure of however is that this is not a psychological thing
resulting from a new piece of equipment etc. The difference in sound
quality is obvious and significant and the effect demonstrable to others.
The problem is that you may be "sure" of this, yet may be wrong in thinking
so. :-)
I routinely hear 'changes' from one day to another in all the systems I
use. I don't (in general) think the systems are changing though. I assume
it is due to changes in my perception, signal level altered, hearing
expectations adapting due to having listened to a different system for a
while, etc.
Has anyone got any suggestions. Ideally I would like to be able to do
something the have the magnificent sound which I only seem to get for a
few days continue on a permanent basis.
Cleaning contacts or resoldering decent connections is unlikely to have
much effect upon the impedances involved unless there was a quite serious
problem. Also, having cleared such a problem it should not promptly return
unless there is an underlying fault.
One (in principle) example being a high d.c. current passing through the
contacts as a result of leakage from one unit to another. This might lead
to tarnishing with some connections over time. However I'd be surprised if
this was acting as quickly and as repeatable as you describe.
Slainte,
