And what is the advantage of this (Yeah. I'm too lazy to look this shit up.)
What is everyone's thoughts on the Line 6 Spider Vavle amps? The Bogner ones?
Since I like you enough, I'll do the dirty work for you

Guitar amplifiers are manufactured in two main forms. The "combination" (or combo) amplifier contains the amplifier head and guitar speakers in a single unit. The amplifier head or "amp head" contains the electronic circuitry constituting the preamp, built-in effects processing, and power amplifier. In the other form, the amplifier head is separate from the speakers, and joined to them by cables. The separate amplifier is called an amplifier head, and is commonly placed on top of one or more loudspeaker enclosures. A separate amplifier head placed atop a guitar speaker enclosure or guitar speaker cabinet forms an amplifier stack or "amp stack".
I'm not quite sure what the advantage is, but I would think it would have something to do with not having to sacrifice power for space like in a combo amp
