It’s just when it comes to sound quality that we have reservations regarding this amplifier. Our initial impressions are positive. This device has a stronger sound than its predecessor. It has a more substantial appearance and a more consistent tone.

Despite its allure, the original A-S500 had a relatively lean and brilliant balance while the Yamaha A-S501 is more balanced.

It’s also rather loud, with a power output of 85 watts per channel. We put the A-S501 through its paces with a variety of speakers, from Wharfedale’s outstanding Diamond 220s to our reference ATC SCM50, and it handled them all well.


When it comes to packing, we have never expected anything less from Yamaha A-S501. The A S501 has some good functionality. The amplifier is enveloped in a foam-like fabric. It’s mounted atop a strongbox, which is joined by a thin polystyrene block.

Conclusion: Yamaha A-S501 Review

Yamaha has done it again with the A-S501, which is a suitable successor to the preceding A-S500. While the A-S501 has a built-in DAC, updated components, and reworked circuitry, it’s still the same amp we all know and love.

Any improvements you might make to this amplifier would be small. A detachable power line would be excellent, and we would like to see the record output option brought back — it’d be especially helpful considering the A-two S501’s tape loops.

However, with a great DAC and phono stage on board, as well as the A-S501, being a remarkable analog amplifier in its own right, there’s no reason to be dissatisfied with the pricing. It comes highly recommended. We hope you liked our Yamaha A-S501 Amplifier review and it was helpful.
