Bi-amping

There’s a huge audio benefit just not for you. Twice the amp twice the cables for some lucky audio manufacturers. I was biamped with Bel Canto REF1000 mk2s for years and when I started selling them off to buy new, I was surprised at the difference. Like no difference. The 1000s sounded good.

There is a lot of information on active bi-amping apogee speakers, but quite a few people don't like the sound as much as the passive crossover. 

Sounds very technical, to an amateur, my speakers each have four terminals, so the amp will be connected to one set of the terminals, is it as simple as that no setting up need?

Yes, just use one set of cables per speaker and a jumper between the positive pair and between the negative pair terminals. No need for a more expensive bi-wire cable. 

No need for any fancy jumpers! A few inches of copper wire will do just fine. That's what I use on my Snell Type A's.
