The Two Amps and DACs In Full
Topping A70 Pro: $499.00 Amazon eBay
Pros: Audio Science Review measured 121 dB SINAD, so its noise and distortion are transparent. A rated 12.6 W balanced into 32 ohms and 1.37 W into 300 ohms is enough for nearly any headphone, through 6.35 mm, 4.4 mm and 4-pin XLR outputs, and it has XLR and RCA preamp outputs for powered speakers.
Cons: It is a headphone amp only, so it needs a separate DAC. The Topping A50 III matches its rating and SINAD for far less, with power that is still plenty for planar magnetics.

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.
