Buy High Pass Filter or KAB RF1?

I need it because the cones on my two speakers as well as the woofer on my sub are modulating very badly when playing phono.

Everyone here will tell you to relocate the turntable, put it on a maple, slate or granite platform, or tennis balls, mount  turntable to a shelf on wall, change cartridge, etc.  I tried all that, blowing money on 3 different platforms, new cartridge and I STILL had to buy the KAB Rumble Filter.  Save yourself the grief and expense that I did and get the filter.  I can't hear  a difference with and without it and I am feeding it expensive cables to boot.

Thanks Stereo5. Yes, it’s quite frustrating the number of people who say to relocate the table when they know a TT has about two feet worth of phono cable length to work with. There are only so many relocation options. 
On other threads I have asked questions like...what does everybody like better A or B....and everybody seems to want to give C as the answer. Lol 

I have already determined I am getting some sort of rumble filter to try no matter what anybody says, because the problem can come at an instant when I am showing my system like last time I had guests and I want to be prepared. 
I will probably get the KAB and then buy an Atoll phono preamp because they are my favorite sounding audio company. 
I just hope having the KAB and the Atoll feeding into a line input in my Marantz isn’t going to be too many connections.

Do you think it will? 

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.
