My current amp is:
2xUCD400;
+-50V dual linear PSU;
4x4700mkF per rail;
~500W toroid / quad secondaries;
balanced inputs;
input buffer's gain is reduced to ~18db;
PSU voltage drops to ~+-42V @ 4 Oms with 4V RMS input signal (max volume).
I'm planning to add two more UCD400s into this setup for the bi-amping.
1 there won't be any of the crossovers. Is there anything special I should implement for connecting input signals? Just to do the parallel or to add resistors in series?
2 the extra UCD will be loaded by 2 Oms speaker. Hereafter, I'm planning to add an extra filtering capacitors like 2x3300mkF per rail to the new module. Is this OK? Also, I worry that the transformer won't be powerful enough. Would you recommend to upgrade it to more powerful?
Thanks

I may be in a bit of a cynical mood today but I can't imagine any situation, short of a football stadium, were 400 watts is not enough.
I have Magnapan's Supper MMG (with DWM woofer). I'm planing to add second DWM, it has 2 x 4Oms diaphragms. Connecting them in parallel doubles the bass output.

2 transformers in external enclosure - is this pros or cons? I wont be able to fit all that on one chassis.

No problem. Use min. 2,5mm2 wires for connection. Connectors with min 10A current pins and one big power supply capacitor also in the amp housing.
What will be output power of the UcD400 on the 2 Oms? Would you, please, recommend SMPS for single channel.
No experience with low impedance on UCD.
I limit is 19A at 2ohm. Ppeak is IxIxR = 19x19x2 = 722Watt. About 510 Watt rms.
