what are you using for source switching?
The MT has two inputs, it is a pre-amp and power amp setup as dual mono blocks.

You are correct, no balanced inputs, just single ended RCA jacks.

I was thinking of this cabling...

Turntable -> Pre-Amp -> XO >100 HZ -> MT -> A12p
-> XO <100 HZ -> ?AMP -> Woofers

Is that an improper assumption?

that signal chain description seems correct.

The easier option is to use the pre-outs on my Mini Torii and just send that to powered woofers or woofers that have a passive XO.

Pros: Much Simpler, Cheaper
Cons: Still sending 100% of the signal to the Mark Audio A12s

Thoughts on the two options?

well my answer is tainted by the fact as an old pa guy i have a bunch of tuneable 2 and 3 way x-overs kicking around and it's not out my capability to build an active x-over.
speaking of which how familiar are you with mini dsp that might be the ticket for what your thinking of.

My brother has a miniDSP 2x4 and I have tried it, it unsurprisingly pulls all the emotion and soul out of the signal (IMHO). > Hence why I am kind of dead set on staying analog, ideally crossover-less to eliminate phasing issues etc.

Overkill? Maybe.

If anyone is still following this thread I am looking for some advice on pro audio analog crossovers. Specifically, I was wondering if anyone here has looked inside any of the commercially available pro audio crossovers and can comment on the quality of components and powersupply. I have been using a 2x 4th order LR that I built 20 years ago and am looking to go to a 3x. Before building another unit I though I would take a look at commercially available units but don't want something that is inferior to what I have been using in terms of quality.
