The TOPPING PA5 Power Amplifier Is Now Available at Apos Audio

140W x2 of power

We loved the TOPPING PA3s power amp for its ultra-clean, powerful output. Its new successor, the TOPPING PA5, is even more exciting. Featuring 140W x2 @ 4Ω output power and an ultra-low 124dB SNR, it can drive most bookshelf speakers without a bit of distortion. Stack it with the TOPPING E50 and L50 to add ultra-clean power to your audio chain.
