If you don’t know where you are going, any road will get you there….
As @soix so often asks what sonically are you looking to improve ?…..
IF it plays loud enough and can handle the speaker load , amp is the LAST thing i recommend….. i know… big…beefy… heavy… easy sell …
IF you don’t plan on playing records beyond the currently hip fad, as @ghdprentice points out, don’t invest further. IF you do, then you need to focus on transducers - cartridges …. your table will support and reward possibly up to an Ortofon Bronze ( just an example )…. after that work on the other transducers ; speakers….
