THX AAA - World’s Most Linear Amplifier Technology for Headphones
THX Achromatic Audio Amplifier (THX AAA™) ensures the ultimate no-compromise headphone audio experience by delivering the world’s highest fidelity audio with infinitesimally low noise levels, distortion, and power consumption.
The SMSL SP200 THX Headphone Amp is the newest SMSL lineup with the top-of-the-line audiophile high power grade THX AAA-888 technology. This amp is versatile and can be used to drive various headsets, including those that have high impedance, require high current, or need high sensitivity.
The SP200 comes with an included AC power supply and is equipped with XLR and RCA inputs. The front panel has XLR and quarter-inch jack outputs, different options for switching between different inputs and choosing high or low gain. Amir provides a detailed review of the SP200 and its performance on Audio Science Review.
The SP200 has a balanced stereo headphone output, a balanced stereo line input comes with high precision resistors for temperature stability, and a high-efficiency ultra-low noise power supply.
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." - Amirm 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 the SMSL SP200. It makes THX headphone amplifiers more affordable and gets rid of clutter on your desk to boot" - Amirm on ASR.
