I am running a Cambridge audio AZUR 340A and 340C, into a pair of
Monitor Audio silver S1's, now I am very happy with this setup, they
have been getting heavy use the last few days, and are about 4 months
old, nothing has broken, but, the setup has increased in volume,
could it be that the speakers are now finally broken in?, or could it
be someting else?.


Do you mean that the perceived level for a given setting of the volume
control remained much the same for nearly 4 months, but then changed
fairly recently? By 'heavy use' do you mean played at much higher
levels than before, or used for longer periods at a time?



More or less yes, my amp sitting on half way,

By "half way", do you mean that an indicator mark on the voulme control
knob is set midway between the "full clockwise" and "full anticlockwise"
positions? If so, that varies from one design to another but typically
means 20-30dB down on winding the volume to maximum.


with all tone controls bypassed, and using the a/b setting to biwire the
speakers, it has not had a lot of use over the 4 months, max 3 hours per
week, but lately I have been running it for around 8 hours per 2 days.

Assuming that the gain *is* the same, and the effect is genuine, three
possibilites occur to me that involve the speaker.

1) That the suspension has weakened/altered.

2) That the voice coil is heating up, and also heating the magnet.

3) That a component in the crossover has been affected.

I would normally associate (1) with use at high levels, mainly during the
initial period of use. I'd also - as Don has indicated - mainly expect this
to alter the bass response a bit, not to change the overally level a great
deal.

I would expect (2) to occur after extended use at high levels, but for the
speakers to tend to 'recover' as they cool down after use each time.

(3) may occur if a component has become damaged/faulty, or if something
like a bipolar electrolytic was used that has been part-formed in use. If
this has occurred it may be a fault.

I would not expect the actual gain of the amplifier to change. However it
is possible that something has altered. The curious point is if this is in
both channels.




Could it be the Cd player, could it be drivng the amp harder, would this
lead to higher output?, I'm using a high quality OCF connecting cable
between the CD unit and the amp.

As Don has said, it seems unlikely to be the CD player if you have used the
same one throughout. The cable is unlikely to matter - although you may
have had a poor contact previously. But if that were the case it would be
unlikely to be on both channels, and for them both to clear at the same
time. It probably would have also produced distortion that you would have
noticed. So I'd suspect the speakers as the most probably area that might
cause a change. There again, though, it occuring symultaneously on both
channels implies the same process at the same time.

Slainte,

Jim

Nope the same cd player a Cambrige Audio AZUR 340C, I was just thinking
that something go be going pop in the cd player, and has driven the amp
herder?

Most unlikely as any such fault would have to effect both channels equally.

It's almost certainly all in the mind. ;-)

Hello Eddy.

Could you be more precise, please ? I mean, if the whole sound level
(from bass to treble) is stronger, it can be a bit.. strange (or at
least, something to worry about). If only the bass increased, (e.g
under 100 Hz) this could be regarded as normal break-in. (After all,
Monitor Audio are good speakers, with tough bass units, and these
speakers can be a bit longer to make more compliant than "lighter" units).
If this is the case (More bass) nothing to worry about. Perhaps you can
move your MA to keep your bass tuneful and accurate.
If not, as I told you, please tell me more.

It happened to a friend I shared a flat with; he'd had some kind of wax
build up in the ears, and after getting his ears cleaned out, everything was
louder and clearer.
