Hi,

My hi-fi sounds great sometimes and not others. I am told that it needs an
hour's warm-up
and this could fit with the times it has sounded good. For example, great one
evening but
poor the next morning. I leave the electronics on but not playing.


Maybe you could give us the specifics on your system.


Is there a CD that can be played to loosen the system up? I suspect the
speakers most.
Bass extension is particularly absent at times. Any suggestions as to whether
playing a
very low frequency sine wave or similar could do the trick?


Check Acoustic Sounds or Music Direct for a number of test and diagnostic CDs.
I doubt that Bass extension would be that affected by any sort of warm up.
