Is biamping worth the time and effort with emerald physics? 4.3.

Hoping for fead back on this. 
No. It’s a 95dB sensitive speaker that can handle 150W RMS. I bet even a 25W amp would be way more than enough.

Emerald Physics DESIGNED the system to be ACTIVELY bi-amped and includes an active crossover/DSP(, as well as a passive crossover. It’s hard to go wrong, using a system the way the designer intended. Using two identical stereo amps, would make everything more accurate/easily tweaked, of course.  Trust the ones that are ACTUALLY FAMILIAR with their product!
With the right amps, you will certainly hear an improvement. The DSP is very helpful and with tweaking, you should get some nice improvements.
