During the pandemic I've gotten heavily back into vinyl - of course locating and collecting all of my favorite jazz and fusion double bass performances. Unfortunately I'm running a subpar budget turntable that is not upgradeable and there are literally hundreds of options out there (and I don't really know where to start). Needle shapes? Cartridge options? Stylus options? Separate power amp or built-in? Speakers? Subs? It's mind-boggling how many different setups you can get but I want something that doesn't leave the double bass sounding muddy or distorted. My current speakers just cannot handle the lows of the big bass. Any recommendations?
