Suddenly, things are sounding awful...

So I hooked my system back up after about a 6 month absence (though the speakers were seeing constant use in another system for much of that time). 6 months ago, the tonality was fantastic. Things sounded rich and detailed. Now, the system sounds extremely bright (especially on top), very grainy, and much of the detail is gone.

I did indeed change the system's position in the room. But Everything has been repositioned very carefully, and I don't see why there would be any major acoustical problems.

The equipment is as follows:
Silverline SR15 monitors.
Audio Refinement CD Alpha
Audio Aero Prima series 1 integrated
Analysis Plus cabling

The only thing I can think of is that perhaps my NOS tube in the Prima is dying. But could that cause brightness and graininess? Those aren't the symptoms I would normally associate with a failing tube.

Suggestions, comments?

Thanks!

Give it some constant play time... and see how it sounds in a few days. If I recall correctly some speaker cables and interconnects will require a shorter "break in" time after being dormant for many months... mostly a rebiasing of the dialectric if memory serves, however I have had this experience in the past as well...

Keep us posted.

"Everything has been repositioned carefully". Does this mean that you put it in a new location, but carefully, or does this mean that you changed it back to the old position. If it's in a new location, no matter how carefully set up, its bound to sound different because of the way the room treats the sound waves and reflections.

I changed from the speakers in front of the short wall to in front of the long wall and I couldn't believe it was the same system or the same room.

Probably a good time to revisit room induced acoustics.

Maybe your system is haunted! Just kidding, on the more serious side it could be that as your tube breaks in, it will extend itself more in the high frequencies, changing the whole sound. Consider a different tube that has warmer characteristics.

Ditto on the give it some play time. Don't know why but one or two of my components get that tizzy not burned in sound if left dormant too long.
More to discover
