Perspective Change in my Tone

It seems there is a shift happening with my tonal perspective on my tenor saxophone. I feel my tone has lost some of its lushness. Could the sax body (pad issue, alignment issue, etc.) cause tone change? Or could it be my ears (early stage of Hyperacusis or Tinnitus)!? Although when my repairman played his sax (another sax body / mouthpiece) I felt it sounded well although I was in front of the horn not behind it (playing position) and he is a really good long time player. Could it be that my playing style is shifted, i.e. I'm not using the same embouchure, taking the same amount of beak in, same amount of pressure on the reed, etc.? My repairman fixed a few leak spots. I thought I would have less of that harshness and get some of that lushness back but hasn't made whole lot of difference. Has anyone else experienced this that suddenly you are not happy with the tone no matter what? I guess I could go and play with a few other horns in the shop see if I feel any different.
... Weird!
