You want a set of active bookshelf speakers that will actually fill the room and last for years, so you only buy once instead of upgrading in six months. Black Friday is the right time to look because audio gear sees real price drops, and last year's models often hit clearance right as the newer versions drop with minor cosmetic tweaks.
Active speakers mean the amp is built right in, so you just plug them into your turntable and go. We are looking at spending about $420 for a reliable pair that handles vinyl warmth without muddying the high end.
Just remember that the intro window is a deadline, not free money; if you still have a balance left when those 15 months are up, interest kicks in on the whole original amount.
