The Tonewinner AD-1PRE+ is a versatile pre-amplifier that offers a number of interesting features. In fact, it incorporates quality components such as an ES9038 DAC chip combined with two optical inputs, a CT7601PR USB interface, as well as a combination of no less than 9 AOPs (5x OPA1612, 4x OPA1632, 1x OPA1642) and a MUSES72323 volume controller. These components enable it to decode high-resolution streams up to PCM 32bit 768kHz and DSD up to DSD512, delivering a warm final sound with low noise and distortion over a wide dynamic range. When it comes to connectivity, the Tonewinner AD-1PRE+ preamplifier is also extremely complete. Inputs include 4 unbalanced RCA inputs, including two phono inputs (for MM and MC cells), one balanced XLR input, two coaxial SPDIF inputs, two Toslink optical inputs and one USB-B input. Outputs include 2 RCA line outputs and 1 XLR balanced line output. Finally, a trigger connector and remote control enhance the user experience.
