Maybe you can loan them out to some of the people I run into who absoultely swear that there is no difference in sound between......(insert your favorite controversy here).
It's raining cats and dogs
Someone noted in a recent thread that his cat becomes aware when he(not the cat) feels his system is sounding good and jumps in his lap. Well I have a similar experience. We have two cats. The female jumps in my lap when I tweak it and it's correct. My focus is channel balance. After a correct adjustment she'll run up, jump in my lap and face the speakers contentedly. They have good hearing so it makes sense they'd be able to tell. It's uncanny though, that she'd be willing to repeatedly confirm it. I also have a Chihuahua that confirms the same thing. But he does it by freaking out and running to hide in the bedroom. Anyone out there have similar experiences? Go ahead and get spiritual.
