This Yamaha A-S501 review covers the integrated amplifier that most consistently appears as the recommended step-up when listeners outgrow a budget receiver and want more power, more control, and a cleaner phono stage without veering into premium pricing. At around $550 it delivers 85W per channel, a neutral MM phono stage, two speaker pair outputs, optical and coaxial digital inputs, and Yamaha’s outstanding long-term reliability record — a combination that’s difficult to match at this price.
It sits in our roundup of the best integrated amplifiers with phono input as the best step-up option for power and speaker control. This review goes further — covering exactly who benefits from that neutrality and power, how the A-S501 sounds across different music types and cartridge pairings, and when it’s genuinely the right choice versus when a different amp serves the listener better.
Quick Answer: The Yamaha A-S501 is the best neutral integrated amplifier under $600 for vinyl listeners who need more power and speaker control than budget alternatives provide. Its clean MM phono stage is accurate rather than characterful, 85W per channel handles a broad range of bookshelf and floorstanding speakers, and two speaker pair outputs add practical flexibility. No Bluetooth, no warmth added — listeners who want a more musical, characterful presentation should look at the Denon PMA-600NE or Marantz PM6007 instead.
