Objective Opinion? I think I've found it!

I have posted on here before that late at night is the best time for me to listen. Everything sounds more defined. Our dog will lie there during the day when I'm playing music and never take notice. I've played songs by Roger Waters and Pink Floyd that have dogs barking in them, Seamus off of Meddle, Dogs off of Animals and The Ballad of Billy Hubbard off of Amused to Death. During the day, nothing, the dog doesn't even flinch. At night? She comes out of her sleep and stands at high alert, trying to figure out where that dog is. Recently I added a Furman PST-8 and a Green Wave filter. Now, during the day, the dog is taking notice, just like she does at night.  How can it get any more objective than that?
