Does anyone own a tri amped system in Florida I could hear?

Very cool!  As far as same amps for each of the lows/mids/highs for the sake of coherence, that does make sense. My buddy’s approach is a bit different, with different flavors of amp for each, based on his sonic preferences. Similarly, different  cables for same reasons. He however has access to the gear and has devoted endless attention to trial and error. He’s got it tuned and loves his results so far. It has to be very tricky though. With different amp sensitivity, etc. 

Aside, is it best to do all this with DSP or analog active Xover?  My friend uses a K231 by Sublime. Analog. Says it’s the best. 

I personally prefer an active DSP Xover. It gives you many more options. over an analog unit.

Ok. Fair enough. Can anyone comment on the sonic attributes of analog active X over vs DSP active X over?

The best place to do the experiment would be a high end dealer that would have the patience to work with the OP.  Such stores are of course hard to find, but given the amount of money that is concentrated in the state of Florida, there has to be one somewhere.  Has the OP tried Sarasota, Naples, or Miami, just for starters?

are you really wanting to tri-amp or go full active.  If you can find a Linn dealer close by have them demo the difference.  You will be amazed.
