[CQ-Contest] Band-pass filters -- insertion loss

In some current research on SO2R, I was reminded recently that nothing's
for free.  One well-known SO2R op commented that he got only 80 watts out
of the bandpass filters that follow his 100-watt class radios, which in
turn means he can not drive his 3-500Z amps to full output.

Is this typical of the bandpass filters available today -- ICE, Dunestar,
Array Solutions?  Anything to choose among them in this respect, or others?

Thanks in advance.

73, Pete N4ZR

I would vote for second hand IC765 or used FT1000MP. Both are in the range
of 1000-2000$. TS850 can also be a good contender.
