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!

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.

Newbee, that meant that I put the system in a new position with careful attention paid to addressing acoustical problems. You're right that it's going to sound different, though I'd expect the basic tonality to remain at least similar. Perhaps that's not right.

The cables were actually all being used by a friend while I was gone. They shouldn't need any burn in time.

The tube is not new, and it's had probably 50 hours of playing time since I came back. It's a Mullard 6922, the lushest of the lush. Does anyone think it could be dying?

THanks for the feedback guys, I appreciate it all!

The tube certainly could be the problem, Oliver. However, I would suspect that the re-orientation in the room has more to do with it. I rotated our system from one wall to another, and I would have thought that we'd changed at least one of the components. Also, each time you have listened since returning, the amp has had 25 minutes or so to warm up, correct? And you're using all the same cords/cabling as before?
Hope all is well with you,

sounds funny but.... have you made sure that all the contact points have been cleaned on the cables and equipment? Have your actual room changed in it's treatments in some way unlike that which had been before? In the new set up has the placement of the speakers changed in the dimentionality? such as from short wall to long wall? Just some added things to could make a difference for you.

I also think it's the room...

See if you can put things back to the way they were previously. Once you do that, you'll know if it was positioning or if your tastes have actually changed during this time.
