TOPPING A90 Discrete / A90 Headphone Amp (Apos Certified)

Dang it. We hate being the bearers of bad news, but the SMSL SP200 has reached its end of life. Luckily, we have a great alternative for you: the SMSL SH-9 THX AAA-888 headphone amplifier. The SMSL SP200 THX Headphone Amp is the newest product in the SMSL lineup 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 for a high-quality, low distortion sound. This amp is versatile and can be used to drive a variety of headsets/earbuds including those that have high impedance, require high current, or need high sensitivity. The THX patented AAATM 888 is a linear bipolar amplifier circuit with feedback error correction. It eliminates the distortion mechanism of traditional amplifier circuits, reducing harmonics, intermodulation, and cross-distortion by as much as 40 dBs. This creates a realistic fatigue-free listening experience. The SP200 comes with a built-in 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 patented 24W high-efficiency ultra-low noise power supply. Its measured distortion is as low as 0.000078% with a signal-to-noise ratio of 122.2 dB. The CNC aluminum alloy shell chassis reduces the interference and noise to improve the amplifier's performance.

Big power, small spaces The SMSL DA-6 is a power amplifier that outputs a serious 70W x2 of power but takes up less than six inches of space on its longest side. A member of the SMSL "-6" family, it is made to stack with the SMSL SU-6 Mini Desktop DAC and SMSL SH-6 Mini Desktop Amp. Together, they create a formidable audiophile-grade stack at an entry-level price. Aluminum alloy CNC shell The SMSL DA-6 is made with an aluminum alloy CNC shell. Perhaps the greatest chassis material in the world, it is strong, lightweight, and excellent at heat dissipation. Multiple EQ presets Make sound signature adjustments on the fly with the DA-6's built-in EQ presets. Options like "super bass effect," "soft effect," and "clear effect" can correct sub-par speakers or accentuate certain frequencies when you need it.
