Buy High Pass Filter or KAB RF1?


Is a $25 high pass filter as effective for rumble as the $180 KAB RF1?

I would rather spend the lesser amount. Thanks!

The KAB RF1 will do what you want.  The high pass filter won't  I own the KAB, it got rid of every bit of the feedback without altering the bass.  It uses all audiophile graded parts inside.
Thank you very much. It either buy the KAB or buy a preamp with rumble filter I guess. I was thinking of possibly the pro-ject tube box S2 if I don’t go the KAB route. 
I'm pretty new to the forum and have read a thread about rumble filters and how some folks think they degrade the sound.  

I have a second system that I use a MoFi Studio phono pre that has a rumble filter which I use and it works quite nicely.  I haven't noticed any sonic degradation but maybe my system or ears are not quite as resolving as others.
