I posted some basic numbers for the new CM7777 in the Dallas thread in Feb of 13.
I installed that particular amp on my rooftop extended 91XG last September where it's still doing its job. Yeah, I needed the extra gain, I've got a lot of coax that I strung through the house ten years ago.
If you send me your email by PM, I'll send you the data that I pulled last year.
