Some of the responses on this thread are wild. $50-100K to build a good vinyl collection?! That's 1000 albums at $50 each! That certainly could be an enviable collection (depending on the music) but is not required to enjoy having a turntable.
I just got back into analog and am greatly enjoying myself. I certainly have not spent anywhere near $100K on my vinyl collection.
Even though, IMO, I think a turntable analog system almost universally sounds better than digital, that's only half of the joy for me.
Collecting the vinyl, enjoying the album art, the tactility of playing the album, all add to the experience for me in a positive way.
I stopped listening to music often in my system and was basically just using it for videogames or movies for a long time when streaming was my only source.
Analog has me excited again to listen and enjoy.
I would say, with your amplifier, while you may or may not experience a jump in SQ, the connection to the physical media and music might be worth the money.
There's something special for me when removing a favorite album off the shelf for a listen. YMMV.
