Audio Science Review Highlights:

"THX seems to have revolutionized the mid to high-priced headphone amplifier market. It provides a winning combination of vanishingly low distortion and tons of power." - Amir on ASR
"Great to see a new price point also in THX amps. You can add a $100 DAC to SP200 and still be cheaper than the other THX offerings. Needless to say, it is my absolute pleasure to recommend SMSL SP200. It makes THX headphone amplifiers more affordable and gets rid of clutter on your desk to boot" - Amir on ASR
