Hey Tony,
The topologies of the Felicia and the BPT CPC are quite different. The stock CPC uses
high-quality parallel filter network on each duplex...
, whereas the Felicia uses a combination of series inductive element and parallel capacitors. Both approaches have their pros and cons.
The Felicia circuit is more like the Audience Adept.
Based on my experience, BPT products are excellent.
Regards,
Paul
