Alpha Design Labs GT40 Phono/Headphone Amp with DAC

Description
The seriously-shielded audiophile-grade GT40 features a low-latency USB 2.0 audio driver that plays and records at 96 kHz. A likely first for this category, the GT40 includes a built-in low-noise MM / MC phono preamp! Record your favorite vinyl to hard disk via the USB output.

The ADL GT40 features L/R analog outputs, and switchable line or phono inputs with a vivid, captivating sound that is simply unheard of in this category. The ADL GT40 brings Furutech`s signature sound -- smooth, detailed clarity -- to desktop systems, especially with high resolution 24-bits/96kHz files, but even 16-bit/44.1kHz files sound impeccable and very musical.

Features
  • High performance 96KHz/24bit USB DAC `and ADC IC chip
  • Enjoy audio in high resolution at 96KHz/24-bits surpassing conventional 44.1KHz/16-bit standards
  • Incorporates the most trusted driver in professional audio for 96kHz recording and playback
  • External power supply: while a USB-powered device might be convenient, it won`t develop the power required for high resolution playback, so we designed the GT40 with an external power supply to solve the problem.
  • Headphone Amplifier: It contains a high performance headphone amplifier with ample drive for good headphones
  • Analog-to-Digital Converter: The GT40 sports a high-performance ADC IC chip for high resolution recordings via analog inputs including phono, AM/FM radio, or other analog signals.
  • Phono Preamplifier: A first for this class, the GT40 features a phono equalizer for recording your precious LPs. Switch between Moving Magnet (MM) and Moving Coil (MC) or Line input
  • Highest Quality Parts: The GT40 features a high quality amplifier and condenser supporting its high performance analog circuit
  • High End Audio Grade Connections: The GT40 is equipped with gold-plated Teflon-insulated RCA jacks with an extremely high quality aluminum chassis and machined volume knob
