What You Hear and What You Don't
Inside, the premium ESS 9028PRO SABRE converter ensures that the ultimate output is a precise match to the digital source. All common word lengths and sample rates are supported for a virtually endless number of digital sources: USB, S/PDIF coaxial and Optical flank the balanced & unbalanced analog inputs on the rear. An ASIO driver is included to support the DSD profiles on a PC, letting you stream up to DSD256 at 12.3 MHz on a Mac or Windows-based source, in addition to PCM files up to 32-bit and 384 kHz sample rate.
Just as important is the purity of the HDV 820’s amp circuitry, providing confident gain with a noise floor cloaked only in silence. The dynamic range (over 115 dB @ 600 Ohms) and total harmonic distortion is < 0.001 percent, with frequency response extending beyond the 10 to 100,000 Hz range to provide unbiased performance until the very last moment before reaching your headphones.
