Low Frequency Rumble Question


I have a Linn LP12/Ekos/van den hul black beauty analog front end. When I play records from my collection, it is very quiet.

I have recently purchased some reissues of famous RCA recordings from Classic Records (all classical music) that appear on Harry Pearson's "super disc" list. In playing some, but not all, of these records, there is a fairly loud, low frequency "rumble" type noise in some fairly lenghty passages. It never lasts the whole disc, but is very pronounced when it occurs, almost like a low frequency "feedback" sound. This does not occur on my other records.

Has anyone had such a problem with any of the Classic Records reissues?? Could it be a problem with my system? - arm/catridge resonance problem perhaps? Any ideas on why it does this on only a few records?? Thanks for any thoughts.

Based on yr description, it may be feedback brought on by subsonic content in THOSE recordings. One way to test this theory is to listen on headphones with the speakers silent-- if your system can do that -- to see if the problem goes away. If it does, then you need to do a better job of isolating the turntable from acoustic vibration.
Best of luck,
