Records not stored vertically for decades

I’m rather disappointed with these responses. There is simply no reason to reply in such a snarky and downright mean manner. You are not being glib or witty. You’re only demonstrating your lack of civility and proper upbringing. 

I shall skip my traditional friendly signoff. 

But Raul’s pint is valid, especially since we are not sure we have the full story(conditions of storage being the most important). Why not play a few LPs from the bottom of the stack and a few off the top.? Then let us know your results.

@Soix - The records may be noisier and or skippy because the lower ones will have quite a bit of pressure on them so any surface contaminants are going to be well pressed into the grooves.

If 150 records is the totality of your collection, I would also carefully consider the opportunity cost of investing in a vinyl playback system versus what else you could do with your system.

lewm is right. If you have a friend with a decent analog rig, take some samples to him and give them a spin. Given the high cost of quality gear, it’s a good step.

A couple decades of records being stacked may actually help some warped LPs straighten out, in my non-informed opinion
