Why pick the Topping L30: Audio Science Review measured 121 dB SINAD, so its noise and distortion are inaudible. The catch: It has only RCA analog inputs, so you need a separate DAC.
The case for the Topping L50: Audio Science Review measured a SINAD of 121 dB, so the amp adds no audible noise or distortion. Watch for: It has no DAC, so it needs a separate source with line outputs.

Topping L30: $149.00 Apos Audio eBay
Pros: Audio Science Review measured 121 dB SINAD, so its noise and distortion are inaudible. A rated 2.3 W into 32 ohms and 280 mW into 300 ohms drive nearly any headphone, including planar magnetic and high impedance models. It also has RCA preamp outputs and a compact footprint.
Cons: It has only RCA analog inputs, so you need a separate DAC. There is no balanced headphone output, and the only jack is 6.35 mm. The JDS Labs Atom Amp 2 earns the same rating and publishes more power for less.

Topping L50: $169.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 121 dB, so the amp adds no audible noise or distortion. A rated 2,800 mW into 32 ohms and 540 mW into 300 ohms is enough for nearly any headphone, including demanding planar magnetic and high impedance models. It offers a 4-pin XLR balanced headphone output and accepts balanced 6.35 mm TRS or RCA inputs.
Cons: It has no DAC, so it needs a separate source with line outputs. The Topping A50 III rates slightly higher with more rated power for a little more, and the passthrough outputs only work while the amp is switched off.
