LP's... Do they sound better now than 30 yrs ago?

Agree wholeheartedly that well recorded and well cared for vinyl can sound fantastic.  Very fortunate where we live to have an excellent used record store with multiple genre inventories, almost all of which are typically in great condition.  

As a VPI 16.5 user, I'm interested in what brand ultrasonic cleaner would represent a significant improvement in record cleaning technology and results? Suggestions?  Cost?  Thank you for any input.  

The newer lp's are just an lp processed with digital sound, so you won't get the same sound as old lp's that were recorded analog with reel to reel tape.  If you don't want pops,clicks, and wear and tear, stick with compact discs.  lp's sounds degrade a little with each play.

I have found that they sound much better now than they did in the 70s and 80s. That's because I have better equipment to listen. A good turntable and cartridge makes a huge difference!  Especially compared to what I had in college. 

And that's even for vintage records. A good cleaning and they sound terrific, even if 50 years old.  

I have studied vinyl cleaning intensely in my own rig. Every record, old or new, should be thoroughly cleaned prior to play (not every play, just before it is played on your equipment.) To clean a record, it is necessary to cut off the natural oils to release the dirt held by these oils.Special cleaners and diluted denatured alcohol is what I found to be most effective. 

Once you have a clean record, the surface oil must be replenished.If not, you have a diamond riding on soft vinyl and every play will add ticks and pops as the diamond carves the vinyl. Use Grove Glide with the understanding that less is better than more. And no, I have no interest in promoting this product beyond that without it, you will not be treating you vinyl in a manner that results in maximal care and enjoyment.
