Crackle and hiss on some albums

@fuzztone   I also own an ultrasonic LP cleaner.  A necessity if you are interested in vinyl IMHO.  My personal rule is to clean the LP with a bit of Kodak Photo Flow in the water.  This causes the water to sheet off and dry without deposits.  Once cleaned, Nothing ever touches the surface of the LP.  No cloth or brushes that will push dust down into the groves.  I use a Furutech DeStat III to remove any surface charge before playing.  This process has really improved the sound quality in most of my collection.  Sadly, nothing can be done to fix a bad pressing or used LPs that are simply played out.  Cheers. 

The vast majority of my LPs are quiet on any of my 5 TTs. If an LP has objectionable noise, it goes to the recycle bin. I’m feeling a bit sorry for the vinyl martyrs. RBCDs leave me cold.

@OP Some modern pressings are noisy. And some purely analogue recordings exhibit tape hiss. Back in the era when multitrack recorders were limited to four or eight tracks, there was frequently an amount of bouncing done to increase the number of recordable tracks, and this caused increased hiss as the noise from each bounce was baked in to the overall recording.

One thing not mentioned....Also inspect the stylus. Crap can collect on front, back and sides and will contaminate the sound horribly.  

Noisy new albums is mainly a result of poor quality vinyl material used in pressing. Japan used to be recognized as one using some of the purest vinyl quality, dead silent. Nowadays it's a crapshoot at best. Even so I have an excellent analog system with over 2k vinyl, I no longer buy them mainly because of quality issues. Rather, if I must have a physical version of something I discover while streaming, I buy the CD. The main reason is quality, the secondary one is, with the new vinyl craze, CDs are much more reasonably priced than vinyl. It seems to me that the people now just coming into vinyl will have a huge uphill mountain to climb to build a satisfactory record collection. It's always all about timing. I built most of my vinyl collection in the 60s and 70s.
