I dissagree with the "blanket stements" saying that verticle or horizontal, or whatever is the way to go. It depends on the situation largely. I can easily see where, at times, it would be better to possibly do one or the other.
One possiblity for people to STRONLY consider with full range speakers(especially 3 way speakers), is to biamp using an inexpensive(relatively) ss bass amp on the bottom(if covering mostly only bass down bellow 200hz), and whatever amp matches the sonics of your speakers up top!
For instance, Parasound makes SUPERB amps for bass!!! They've always had very very dyamic and authoritative/well controlled bass from these amps, and they come with a volume control to adjust gain as well!...this makes it perfect for biamping in my oppinion.! You can not only level match the two amps this way much easier, but you can take advantage of the excellent bass response from the amp, and let your midrange and top end be handled by a more "finess" amp up top...tube, SS or otherwise.
I've done Biamping in the past, and I like this option, functionally and cost wise, very much!
