The first question you’ll need to ask yourself when looking for a turntable is how you plan to use it. Are you into vinyl for the ritual? If you simply like the concept of physical media, having to flip a record to finish it or the need to intentionally swap out an album when it’s done, that’s just fine. You probably can make do with a more affordable turntable since overall sound quality may not be a main concern. If you crave the warmth of analog sound, and you want the collection you’ve invested in to sound its best, you’ll need to consider something with better specs.
