Buy High Pass Filter or KAB RF1?

Also, how do most people have the KAB hooked up?

I biamp my speakers so it would have to be between the TT cables and the Marantz Preamp Processor for my system.
The problem is that this means that I will need rca cables for between the other side of the KAB to the Marantz phono inputs right?  Maybe they sell 6” pigtails.

My preamp has both a tape loop and processor loop.  I run it through the processor loop.

Another option!

Good call, had forgotten about those.  It's cheap enough, I would give it a try.
