Hi everyone, I have had a small vinyl collection for some time, but only recently decided to purchase a player and start listening to my records. Because of my budget and inexperience, I bought a used Technics SL-23 on eBay. It was very cost effective, but when i plugged in my speakers I found a big problem. I've been looking through this thread and found the reason why (or at least I believe I have): using the aux setting on your speakers isn't the correct way to use your turntable. So, my question (and maybe I have missed the answer on this thread) is does anyone have any suggestions/instructions on what i need to be looking for when i go out to buy some speakers? What should I avoid? And what specifically will my speakers need? Your help will be greatly appreciated, even if it's to point out that I've made a huge mistake and need to start over. Thanks!
