Big 2 channel Amp OR Smaller 6 channel and TRIamp?

Speakers: High end w/TRI-AMP binding posts.

Which amp scenario would you choose?

A - 2x300W Discrete Amp, use jumpers to connect 3 posts together on each side and run 2 speaker wires to each speaker.

B - 6 or 7x100W Discrete Amp, no jumpers, run 6 speaker wires to each speaker.

Speakers are KEF Reference 203.1 but that shouln't matter for discussion sake. The above scenarios could be applied to biamp speakers as well.

Same old, same old. (A) without doubt.

With scenario (B), your woofers would see only 100w.

For the KEF Reference 203.2 (could not easily find the specs for the 203.1), the LF crossover is 300Hz in these speakers and sensitivity is 89dB/2.83v/m so the woofer eats half the power and the power rating is 50-200w. So, I would guess, again, that the 300w amp would be the more effective solution.

Can you explain how you reached this conclusion? AFAIK, the current (and power) required is a function of voltage swing of the source and the impedance of the load.

Headroom, of course, is not power, per se, unless it is used. So, do you think that the OP's scenario (B) is superior to scenario (A) for that reason?

How about you bi-amp, with 200 wpc for the woofers and then use a second amp for the mids/tweets and jumper them?
Jumper what? Why? Cannot think of a jumper in this situation that would not create the potential for a short.

Sorry. I forgot about the OPs three pairs of terminals and was trying to fit your suggestion into 2 pairs.

Just get a big enough amp. That's all.
