Tonewinner AD-1PRE+Preamplifier Class A/B DAC ES9038 32bits 768kHz DSD512
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.
Tonewinner AD-1PRE+: an audiophile amplification stage
As the ToneWinner AD-1PRE+ is above all a Class A/B preamplifier, the brand has chosen audiophile components for its amplification stage. There are 5 AOP OPA1612, 4 AOP OPA1632 and 1 AOP OPA1642. These components deliver low-noise, low-distortion sound, for a pure, transparent signal at the AD-1PRE+'s outputs.
Tonewinner AD-1PRE+: ES9038 DAC and CT7601PR USB interface
The AD-1PRE+'s optical and digital input interface incorporates an ESS Technology ES9038 32-bit DAC chip and USB interface. This enables this preamplifier to support high-resolution PCM 32bit 768kHz, DSD DoP256 and native DSD streams up to DSD512. In addition, it supports numerous formats such as SACD, ISO, DST and DFF. These features allow you to make the most of your music library, and to link a wide range of devices to the AD-1PRE+, from CD/SACD players to network players.
Tonewinner AD-1PRE+: Phono-compatible inputs
This preamplifier features two Phono-compatible RCA inputs, one MM-cell-compatible input and one MC-cell-compatible input. A very useful feature for fans of 33 rpm and 45 rpm records, who will be able to use the AD-1PRE+ directly with their turntable and enjoy their vinyl collection with a high-end Hi-Fi system.
