Rumble - turntable or background noise DG LP


Context: Not really audiophile guy. Set up: AXR 100, Debut Carbon w/Ortofon Blue, KEF LS 50, BW ASW 8 Sub. I am a subscriber to LA Phil so I know what things should sound like. 

I notice a fair amount of what I would call background noise and sub flutter or pulsing when I play Dvorak New World - Berliner/Kubelik and Beethoven 6 Wiener/Bohm. Both are new DG and "remastered". The sound otherwise is very good but the background noise is annoying. When I play C Botti Vol 1 on Blue Note, or one of the 45 RPM  like Brubek or D. Krall they are really quiet. You have to want to find the noise. I have double checked the stylus for proper set up. 1.8 on the nose by measurement. Any idea on why the DG's would be so much worse? I have compared the DG vinyl with the same DG CD's and well, for reasons the defy explanation, I like the sound of the vinyl much better except for the background noise.

Thanks

Again,  "groove roar is actually rumble from the poorly machined bearings" would be heard on ALL albums played on this turntable. Is it that complicated?

Suggest you take a 'good' record and a 'bad' record to your local HiFi dealer.  Explain that you'd like to listen on a good turntable to see where the rumble might be coming from.  There is the chance of a turntable sale if it is not on the record!

Sometimes traffic noise makes its way into a recording, or even the sound of the air-conditioning at the recording venue.  Or it could be a bad batch of vinyl.

@richardbrand has a good suggestion. The OP should get their own system out of the equation if they think the records have an issue (and I have already commented the DG TOS reissue doesn't have that issue here). Play them on a known good system before putting it all on the pressings is not a bad idea.

I still say issues like these are often down to inadequate isolation more than anything.

richardbrand - Good suggestion- let me ponder where. 

Update - I moved the sub about 20"+- away from the TT cabinet that it rests on. Could hear no difference the rumble. It is in a corner and toed in very slightly - I had to lower the volume a bit but it seems to be more omni from that position.
