High-Power Balanced Amp for Your Desktop Setup

Powerful, affordable, and easy to use, the SMSL SAP-10 balanced amp shines when it comes to balanced headphones like the Massdrop x Sennheiser HD 6XX—and it’s well suited for headphones with single-ended connections, too. It uses two advanced TPA6120A2 headphone amp chips to deliver ample power and low distortion, and also features a low-vibration Triad transformer, four 300uF Nichicon FW series capacitors, 10 Epcos standard film capacitors, and a four-channel NJW1195 volume control chip for a balanced output from the right and left channels. This amp puts out 660 mW at 32 ohms and 170 mW at 300 ohms, powers on in just 2 to 3 seconds, and uses panasonic relays to protect your headphones from damage. LED lights indicate the input: blue for unbalanced, purple for balanced, and red when powered off.
