Thank You for chiming in to assist arvincastro -

Happy Listening!

Unsound - Regarding impediments to CS5i ownership, I am confident we can address the primary shortcoming quite easily - and that the amplification problem would be reduced significantly. The impedance drops to 1 ohm in the deep bass and doesn't rise above 3 ohms till 200 Hz. That severe bass load drains the amp of ability for transient response in the upper bands. By adding a second input for the 3 woofer/ subwoofer drivers, we can sequester the "amp problem" to the bass.
From history: Jim was aware of the problem and the solution. His personal make-up caused him to avoid the fix due to the potential chaos of cable and amp interactions in the field. However, if you used 2 identical amps with identical cable runs, you could successfully vertically bi-amp each speaker with its own channel for each band. As was mentioned earlier, each amp could sit close to its speaker so the 4 cable runs would be less expensive.

While in the XO we could easily upgrade some caps and resistors if desired.

In addition,  according to Paul at PS Audio,  not only do mono blocks let you play louder,  the sound quality is substantially increased with greater definition and a larger sound stage.

Unsound, you probably know that the xo is a parallel design and each section is wired to the binding post. To bi amp is only a minor modification.
