But critics note that its build quality is much better than you would expect from an amplifier in this price range. Regardless, the amp offers six pairs of single-sided pairs, one pair of balanced (XLR) inputs, and two sets of speaker output terminals with plastic-protected connectors suited for banana plugs & pins, but not for audiophile-grade cables. Also included are many control options, including bass, treble, mono left/right, balance, second zone source selection, selectable biamp, volume, etc. Overall critics praise the M3 for quality, crisp audio; a durable build that’ll last years; and a minimalistic and easy-to-operate user interface.
