Is it Me, the Vinyl or the Equipment?

I'm not a vinyl guy, so take this for what it's worth.

Is the problem only on these two records?  If not, it's probably your TT.  I have read of some tables needing a subsonic filter.

Interesting. I had not heard of this before but it may be worth exploring the filter. 

IMO, its something in the system. maybe your phono preamp. They have a lot to do with the sound of the TT. If its a tube pre, it may be a bad tube. Or if not, it may not be up to the task. Did you set up the cartridge? How about the cable from the TT to the pre? Is it a low capacitance cable? Do you have the ground wire hooked up properly? 
These are the things to check. I doubt it is cart setup. But I may be wrong. Check ground first. And if tubes, switch them. Cable next. Then, as another poster mentioned, IF your other albums don't have a problem, It may well be the pressings of those albums. Stuff DOES happen. Good luck

It’s called rumble, two fold. The weight is to great on the head shell or something need service. Rumble is the floor noise of a given TT, it can be reduced a lot or increased because of maintenance.

BTW ALL the older Preamps had filters, the better the preamp the better the filters.. Rumble and Tape filters, were a just of a few.. The reason I like Mac.. They had the BEST filters and lowest floor noise, when NOT using them. Fisher was close too..

Oh one other thing.. I could be wrong.. :-) Get some springs under your TT.

TT 101, get springs, get deadening matt, get HEAVY. I use Russco broadcast TT. They have a TINY bit of rumble.. I keep a cool 1/2 dozen TT here for builds.. Garrard Killers... Russco, QRK, Sparta..
Close to my Thorens.. Better than Garrard though, hands down.
