i have never had a problem with Woofer pumping in any system. I have heard about this, but whether it was an entry rotel preamp and Dual 721, to my current RCM Sensor II Phono preamp, ZYX UNIverse II, Pass Labs Xp10 and XA 30.8 etc, just have never see this issue. Have you changed the cartridge to see if there is a special resonance you are coming up with?
Woofer pumping WHY??
Hello All, I have an older REL B2 series. I love this sub. I recently received a new Project Xtension 10 with Clear Audio Maestro Ebony v2. After a couple days I noticed bad woofer pumping on several records I like to listen too. When I brought it up to Needle Doctor they told me it was my records and said it worked fine in there store. Now my REL is blown! I am so upset at myself for not taking this matter more seriously. Now I am purchasing a KAB rumble filter because I am not going through this again. Is this a cartridge mismatch?? Because on my REGA with Dynavector 10X5 It did not do this woofer pumping nearly as bad. AND I do remember putting a DENON DL103 on my RB301 and this same woofer crazy action occurred!! Immediately took it off that arm. I just spent $4100 for this Xtension10/CA Maestro and now I am scratching my head. Hmmmm.
