From modern DSD files to the favorite discs in your CD collection, all are received with absolute accuracy and reproduced without extra flavors ever getting in the way. 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 \u0026amp; 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.\u003c\/p\u003e\n\u003cp\u003eJust as important is the purity of the HDV 820’s amp circuitry, providing confident gain with a noise floor cloaked only in silence.

Total harmonic distortion is \u0026lt; 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.\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"content-with-image__headline\"\u003e\u003cstrong\u003eYou Have New Connections\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt’s easier than ever to insert the HDV 820 into your hi-fi setup.
