Default Best Alephs for a bi-amp configuration

I'm currently using this setup:

HF: Aleph 3
LF: Aleph 0s

I am considering to keep the Aleph 3 in HF and replace the Aleph 0s with a two stage Aleph 5, or to replace both by a Pass Aleph 4.

HF: Aleph 3
LF: Aleph 5 (or another 3)

or Aleph 4 stand-alone.

Some important notes:
- The Aleph 3 alone fails on controlling the bass, as the load is difficult (unstable impedance curve, low sensivity, etc).
- The Aleph 0s manages to control the woofers (not exceptional, but good enough).
- The Aleph 0s sonic ability has not the Aleph 3's magic, and since crossover is at 2.5KHz, in a certain way it "spoils" the midrange.

And the natural questions:
- Would one Aleph 5 in LF (0-2.5KHz) be enable to control the woofers well, prevailing the sonic talent of the Aleph 3 in the midrange?
- Could one Aleph 4 beat a Aleph 3 + Aleph3/5 bi-amp combination?

Best regards

an Aleph 4 is not for difficult loads. Try a 5 with higher bias (or a 4 with higher bias for even more heating). You could also try a 3 with higher bias and maybe a bit more ac-current-gain to get your bass under control.

Among the Pass products, the best bottom end control comes
from either the Aleph 0 or the X and XA amps.
