Is it possible to have vinyl nearly noise free?

this is groove echo caused by modulation bleeding through from the adjacent track -- you can hear it both pre and post (one on the left, the other on the right) and it disappears completely on loud passages where the grooves are widely spaced -- luckily it’s rarely this bad. The 2 second lag (one revolution at 33RPM) is also a give away

@folkfreak I've cut a few records and not experienced this. My lathe is a bit older- so it only has fixed groove spacing. We modified it so we can run variable groove spacing but either way never get print-though issues. When you look under a microscope at the grooves you can see why- unless you over cut the record the grooves are spaced from each other. Overcuts (grooves too close) often results in distortion. If you really are getting print thru from an LP, its poorly mastered!

Absolutely a mastering issue!

I suspect its a combination of
a) late 70s poor quality vinyl,
b) quad and
c) trying to cram too much on a side -- each side is running a good 25 min + with most of the loud music at the end of the side (esp on side 1 which is where the problem is worse)

I'll look to see if I have that record- i have a bunch of ASDs, most go unplayed. Was it only released as a 'quad' record? 

Yes -- six of the seven Berglund symphonies were recorded in Quad, they’re a great set but I cannot recommend #1 in this original pressing.

Side 1 is >27 minutes which is pushing it for heavily modulated classical

I took a quick look and didn't find it, but that doesn't mean much- partly due to how the classical stuff isn't completely organized here. When I moved a couple years ago, I kind of back-binned several thousand records in one room and I go 'shopping' there periodically.
 I also have a 4th dimension problem- you ever experience that? You know you own a particular record, but you search repeatedly and can't find it. Sometimes, you buy another copy if it isn't crazy money. And then, one day, when looking for something else, the thing just pops into your hand?  I really think there is this dimension where records go sometimes.... 
Go ahead, make fun of me.

Yeah, I remember the SQ/QS stuff from back in the early-mid '70s, whenever that was. I started buying EMI ASDs first for Jacqueline Du Pre, then kinda bought 'em whenever I found them. 
Haven't listened to the Sibelius symphonies in quite a while. Somebody mentioned a Barbirolli of Mahler's 9th here.  I did find that, as a German Odeon. I'm not sure how old it is, it came from a collection that stopped in '91 when the owner passed away. Man, I should get back to listening to classical more. Time waits for no one.
