Well, since I'm using a total of FOUR 200X3 amps, bi-amping my Front L+R, and tri-amping my Center, of course I hear a difference!
It's these other non-audioholics around me that don't know anything
See what I have to put up with?
They looked at the back of my speakers and said, "Why the heck are there so many wires coming out of your speakers? Is that for real? What's the reason?"
So I said, "Well, they significantly improve headroom, clarity, imaging, and detail! There is a separate amp for the high frequency, the mid-range frequency, and the low frequency."
They said, "well, we don't hear any differences."
I said, "First, my system is so good that you won't be able to distinguish unless you know what to listen for. Your hears aren't trained."
They said, "You are so full of it."
I said, "Thank you."
