Is this player any good? I've been planning on starting a record collection for a long time. My mom got plenty of awesome rock records of Zeppelin, Hendrix and Deep Purple to start with. If this is a good starting point, it would be great. I was about to spend 50 bucks on a Pioneer 510A, as suggested in the first post. But now I can spend that 50 on maybe upgrading this thing.
I'll be honest with you guys, I was unfortunate enough to get born after the vinyl era, so I don't know at all how these things work.
I understand that there is a cartridge and a needle (also called stylus?). From what I understand, these two are the main factors of audio quality. Can you guys explain a little how it all works? Does every cartridge work on every player?
Say I got this thing, and I got 50-70 bucks to spend, on what should I be spending it, if, at all? That money is just a starting point, though. I find it fun to upgrade my stuff. Is this table also suited for that?
Looking forward to your replies! Thanks.
