Help with Turntable/arm/cart decision

So the Turntable (Project Xtension 10) arrived 3 days ago, and from the moment I placed the needle down on the record I realized that this was a couple levels up from what I was used to. First the sound is flying out of my speakers like never before! Also, there is more everything. This table Rocks on Led Zeppelin Song remains the same album, the song "No Quarter" Has immense weight and force, Jimmy Pages guitar is like a well sharpened knife slicing away while Plants voice is rich, full, powerful and detailed. I have been spinning everything from 80's pop to 50's jazz and One thing I was really aware of was the way it presented the event very forcefully with great tone and weight, ultra detail, dead solid speed control, over my REGA P3/24 w/Dynavector 10X5 (very good combo). I'm still going thru break in and so far I am blown away with the beautiful dynamic and detailed sound from the Clear Audio Maestro Ebony v2. This MM (if the midrange ever opens up) is one of the best cartridges I've heard MC or MM. I still love Low output MC's don't get me wrong. more to come later. Ill post pics in my system soon. This thing is GORGEOUS in piano black laquer finish too.

After 2 days of listening to the Xtension 10 with Clear Audio Maestro Ebony v2 , I was noticing major woofer pumping on several records that I like to play. I told Needle Doctor and they are unaware of any issuie with this Tone arm cartridge combo. They told me it was my records and said that the unit worked fine at there store....So after trying to be careful, NOW MY REL IS BLOWN!! I am going to purchase a KAB rumble filter because I am very upset that this happened. I even saw it occurring and dismissed it! I am ashamed at myself for not realizing this would happen. I think its not a good cartridge for the 10cc EVO ARM. (bad woofer pumping to me indicates a bad cartridge arm match). What do you guys think? Anyone have experience with this cartridge ??

Never had that problem. I run a Basis with the Basis 300 (Rega arm) and a Benz Glider. I get plenty of bass if it't recorded and it tracks like a pro. Sucks that you blew your sub. Is there something wrong with the set up possibly?

After spending more time with this it seems that the cartridge and tone arm are a great match as I am getting awesome sound. As for the REL it started making scraping sounds and I'm not sure If they are even related. I might still buy a KAB rumble filter though, because I don't like seeing my Dynaudio drivers moving in and out so much you can hear them fluttering sometimes.

It's strange to me, but I'm no expert. Did the Rel give you problems using other sources? I'm sure there are some expert TT guys who may be able to help you out before you have to start with filters. That may be the way, but I wonder how many are using a filter. I haven't even seen one or heard about them in a few years and I've been to many dealers and listened to countless set ups from 300,000 down to Rega 1s. Very interesting situation and I'm sorry you are going through this.
