WooAudio 3+ is an enhanced model of the WooAudio 3, featuring a filter choke in the power supply while removing the pre-amplifier output scheme. The WA3+ increases output power and thus better synergy with low impedance headphones than the WA3. This model retains sound signature of the WooAudio3 as it pushes to a higher performance horizon.
