Thanks Tyson, so you’re recommending the Otica MTM setup sitting on the subs instead of the floor standing model? That could save me some $$$.
I’m very interested in hearing opinions on a nice, but affordable way to drive these speakers too...
Yes, that's exactly what I recommend. Here's why - the full range towers will have passive bass that cannot be tamed/EQ'd like the subwoofers can. Passive OB bass like in the Otica Towers is certainly better than box bass in closed speakers. But OB bass in the Servo Subs is even better because each sub is individually tunable to the room via the volume, phase, damping, EQ and Extension settings.
The "even better" part of the Otica MTM is that whatever amp you pick to drive them won't have to do any bass duties, so you can pick a smaller, more refined, more beautiful sounding amp that only does mids/highs, while leaving the crushing bass duties to the dedicated servo sub amps. That's how I run my speakers (the Super 7s), and it's an absolutely brilliant design approach.
When you say "affordable", what do you mean? If you want a couple solid recs from manufacturers here on AC, then the smaller Odyssey amps are very good for class A (and AB) solid state amps, while the DAC amps are very good if you want a high efficiency (and small) digital amp.
For a preamp I'd rec a good tubed pre, just as my own general preference. There's lots and lots of good ones around, especially used.
