S.M.S.L - SP200 THX AAA-888 Headphone Amplifier

DESCRIPTION:
The SMSL SP200 THX Headphone Amp is the newest product in the SMSL line-up with the top-of-the-line audiophile high power grade THX AAA-888 technology. This technology allows for the highest fidelity with extreme output power and ultra-low crosstalk. This amp is versatile and can be used to drive a variety of 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, options for switching between different inputs, and choosing high or low gain. A detailed review for the SP200 and its performance is provided by Amir 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." - 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 the SMSL SP200. It makes THX headphone amplifiers more affordable and gets rid of clutter on your desk to boot" - Amir on ASR
