Buy High Pass Filter or KAB RF1?

@yogiboy...……………………………..

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

So I called the company and the guy said the $22 passive version is pretty much just a high pass filter and would technically make an audible difference. He said they have an active product around the same price as the KAB now where you can’t hear the difference when using it. 

I just ordered the KAB. I can’t take this anymore. lol 

Rega thinks it’s a cartridge mismatch but my cartridge only weighs 2 grams more than the one that comes with it and the compliance is spot on I think. 
I think the needle is picking up feedback from the speakers.

being new to this stuff I found that people have an argument that doesn’t make sense. They ask why a filter is necessary and act like it’s a band aid. Yet, these same people will tell you that even rumble that you can’t hear is bad for your system. So that means their systems may be rumbling and they don’t even know it. Why not have this in the system to protect it if nothing else. I haven’t heard one person say it degrades sound. 

Craigert,  Based on one of your posts here, do you seriously plan to put the filter between the phono cables and the phono input of your preamplifier?  If so, that's a no-no, if you care at all about SQ.  If you're bi-amplifying the speakers, do you use an electronic crossover?  And do you have separate amps for bass and treble?  If so, put the filter at the output of the crossover that feeds the bass amplifier. Whatever your set-up, I suggest you avoid putting the active rumble filter directly across the very low voltage output of the cartridge.

Lew,

Thanks for the tip. The ultimate goal is to buy the Atoll phono preamp and put the KAB on the back side of it before it goes into a line level input of the Marantz.

i have a 5 channel amp that feeds my front two speakers and my sub has its own built in amp. 
The crossovers in the front two speakers are built into the speakers and the crossover that controls the sub is in the Marantz. 
There is only one line feeding the sub so I’m not sure how I would connect this just to the sub.

Do I need to wait until I receive the outboard preamp or is there a way to Connect in the meantime?
