I thought this question was pretty obviously not on topic, but opinions seem to differ.
The answer you'd give someone wanting to be a turntablist, and to someone who just wants to listen to music, are completely different. For creative DJing you want variable speed, bidirectional needles, rapid start and stop, etc. For listening to records you need none of this.
This question is explicitly only about listening to music. Hence if you have an answer aimed at musicianship, you wouldn't be answering the question.
Hence, for me, it's off topic.
You might argue that a Hi-Fi is a tool for musical appreciation, and that musical appreciation is part of being a musician. But even in that case, this question is analogous to "my local library stocks musical scores -- how do I apply for a library card".
I'm surprised not to see a "home entertainment" SE, where this would fit fine.
Clearly, the questioner is only going to listen to vinyl records. It's also very basic, a quick google should turn up answers enough. Just as questions about how to use your microwave (cryptic enough to warrant a question) probably isn't going to fly on Stack Overflow, I don't think this have is on topic here (if we are looking to build a build a community of musicians, rather than a place where all music related questions are welcome).
Although I have voted to close off-topic posts in the past, I voted to leave-open and reopen this question. Yes, it may be rather straightforward, but I think it is valid, and think that we're being a little mean-spirited closing it. Leaving it open wouldn't create undue noise on the site.
Although the OP may only be trying to find out about record-players, I still think the question has merit for several reasons:
- The specific equipment used for a good record player and audio setup has similarities to equipment used for live performance with other instruments or audio equipment.
- Although the OP may not be interested in using a turntable as a live performance instrument, many musicians do, whether as DJs or in many styles of popular or contemporary (art) music.
- Why not let somebody ask a question related to the process of listening to music? I spend about half my time as a musician listening to music. (Okay, I haven't used a record player for years, but hey…) I doubt we would close questions related to reading about music...
If the question and answers can be useful to create, perform, or practice music, then I think the intentions of the asker are not important.
Imagine someone comes and asks about the harmonic content of different types of keyboard and pianos, and how materials, shapes, and acoustics in general affect the tone of it. Then he specifies that he wants to know because he plans to eat a piano with a very rich harmonic content.
His intentions are gourmet and not relevant to this site but the question and potential answers are on-topic (as on-topic as it gets) and can be very useful to musicians.
We can share scope with other professions, hobbies, activities; and it is not a bad thing.
If the off-topic specifications still bother you, I think a better approach would be to edit out the irrelevant or not important parts.
