AIYIMA DAC-A2 Mini USB Powered DAC Headphone Amplifier AMP PC-USB/Coaxial/Optical to RCA 24Bits 192KHz, Audio, Soundbars, Speakers & Amplifiers on Carousell
My (well, comparatively) budget setup. AKG K702s, Aiyima DAC-A2 and FiiO M3K. The DAC isn't great but it's a hell of a step up from the Macbook's headphone jack, IMO. Lucas amiibo
