I'm not sure if this is even possible but it seems that my receiver doesn't sound as loud as it used to. I have an Onkyo 805 that's about 4 or 5 years old. I haven't changed speakers. I also haven't done any tests so this is just based on what I feel. Sorry to post this stupid question but I'm just curious to know if anyone has ever experienced this.

Thanks,
Chester

Hi Chester,

Have you confirmed that all of the main channels are operating at similar output? Try the Dolby Digital pink-noise setup signal that rotates from channel to channel and make sure they are at roughly the same output levels.

Perhaps one of the channels has become intermittent or you might have inadvertently changed one of the level settings for one or more channels. It's possible that one of your front channels may have cut out totally.

In a correctly operating solid-state amplifier, it would be most unusual for it to "lose power" over time. This can happen with tube gear as it ages, but not transistor equipment.

Regards,

Check the speaker wiring too. It's possible the exposed copper wiring has become stiff and has started to fray away.

That's unlikely to be the issue. If distortion were a problem, maybe, but it's not going to get softer because the last inch of the wire is a smaller diameter.

A reciever losing power would be about as weird as a pigeon with the face of a Saint Bernard!

There are days that my system has to be turned up a little more to get the same perceived level of sound that I attribute to my allergies and head congestion. Some days I just don't hear as clearly.

That's an interesting comment. Wonder how you would do on an inkblot test?
