System suddenly sounds terrible

[Standish]

For the last 2.5 years, I've had a Yamaha v1700 with Vienna Acoustics Schonberg speakers and a Subson subwoofer. Just this week, I've noticed (or I think I notice -- no one else in my family does) that it suddenly sounds flat. Sort of like all the tweeters were blown -- but they're not, because there is still sound coming out of them.

Is there anything I should check before I send them across the country to Berkeley where the only authorized service seems to be?

Thanks.

Do you have another receiver you could test them with? Maybe the receiver is going bad.

That would eliminate one of the two variables, wouldn't it? I don't have another receiver, although I was already thinking of ditching the Yamaha, which I hate.

Is this a way in which a receiver can go bad? I.e., sound quality somewhat diminished?

Not an expoert on this, but if ... well, if some components are "blown" somewhere in the receiver, guesss this could happen, do you have any other speakers to hook up to the receiver, to see if the receiver works well with other speakers.... So you know if it's receiver or speakers....

A couple of other possibilities...

By chance did you lose power where your EQ settings could have been reset?

And since you say nobody else notices the difference I gotta ask... could it be possible you have a head cold or an ear infection? ...

1) Double and triple check all of your wires and connections. Always sounds silly, but SO many times, it's just a wire that's come loose somewhere.

2) Have you possibly moved any furniture or brought a new object into the room? Any changes to the environment (the room) can have a larger impact on the sound than you may think.

3) How are the speakers coupled or decoupled to/from the floor? Check your spikes/feet/stand. I once had a speaker that used fairly tall rubber feet on its bottom. I have medium carpet in my room, so I really didn't see, but somehow one of the back feet got "crushed" and that made the speaker more directly coupled to the floor and also changed the angle a little bit. Sounds like such a small thing, but it honestly changed the sound.

4) Double and triple check your receiver's sound mode and setup settings. They may have accidentally been changed or reset.
