Low Frequency Rumble from TT between songs

@dhcod , sorry about the late reply. I was not aware of your post.

My version of accurate has several facets. First is measurable accuracy, the stuff most audiophiles hate like the opposite political party. Frequency response, distortion of all types, signal to noise ratios. Slew rate, etc. 

Most systems fail right at the start because they do not have speakers that are reasonably flat with matching frequency responses in the room and position they are put in. It is not easy to be accurate.

The second facet is subjective but not just my opinion. Others will hear the same features and usually agree. This is the ability to produce life like images and timbre with the right recordings across the frequency spectrum. A system that performs at this level will impress nine of ten lay people. If the people are very use to hearing live instruments that climbs to ten out of ten.  I have seen the reactions to several such systems and they were extremely similar in content. 

The problem for most of us, whether we believe it or not is that we do not fully understand or relate to what we have not experienced. Very few systems perform at this level and price is no indication at all. Go listen to a string quartet live. You want to put that in your media room. That is why I use "live" as a reference. You can not use anything else as a reference because most systems do not perform at this level and are a maze of compounded errors. It is also easier to hear a live performance than it is any one particular system. You want to know how a piano should sound? Go see a solo McCoy Tyner concert at a small jazz bar. 

@dhcod , that is all fluffy subjective garbage. 

What I am trying to impress people like dhcod with is this is not subjective, it's what I like to hear stuff. That is an excuse to validate inferior equipment. There is accurate reproduction and there is everything else. There in only one accurate. Any deviation from accurate is inaccurate.   People think that because accuracy is hidden from everyone that they can make up any definition of what accurate is, a definition that is of their liking. Sorry, doesn't work for me. Accuracy can be found but it takes a kind of persistence most of us do not have. Nor do they really want to. They have more important things to do. 

It left you missing distortion. Isn't it a strange life?

@dhcod , acoustic feedback occurs at a specific frequency and is a steady tone typically described as a howl. 

Rumble is very low frequency and lumpy for lack of a better term. It is low frequency garbage for either the bearing of your turntable or the bearing of the lathe that cut the Lacquer your record was produced from. If it is your turntable it will be consistent and occur with every record. If it only occurs with some records and not others the fault lies with the manufacturer of the record. 

You hear it now because your new speakers are capable of reproducing those very low frequencies. Rumble is one of the banes of vinyl reproduction like scratches, ticks and pops.
