Hello,
Unless you need the space or money I would get the TT tuned up. Plus, Knowing it all works properly makes it easier to sell. Most people do not listen to their whole collection. Some are not being streamed or the pressing is not being streamed. Sell off what you don’t listen to anymore or the duplicate pressings. As far as the sealed albums I would sell them. You are deciding to sell stuff anyways so why keep the vinyl you won’t open anyway. I have purchased three sealed Pink Floyd albums and listen to them. Some can be worth good money. Your gear is really nice and can be sold at anytime. I think you should do this in phases so you don’t get buyers remorse. I love streaming too, but there is something about playing a record that I love. To me the sound is different. It should not be an all or nothing decision. I hope this helped.
