The Pioneer A-401 sounds clean, punchy, and slightly on the bright side, with tighter bass and more edge up top than classic warm amps. It leans neutral-to-forward, favours clarity over romance, and keeps things crisp without getting truly harsh. Less cozy, more honest. Good if you like your music awake and paying attention.

This unit has been serviced to factory specification (bias adjustment, balance adjustment) and comes with a 6 month warranty.
