Matias Posted February 20, 2010 Share Posted February 20, 2010 Why do some DACs and transports/interfaces provide dual SPDIF? What's wrong with a single SPDIF coax? I mean, my ESI Juli@ output up to 24/192 and my Benchmark DAC1 receives up to 24/192 in the same single RCA SPDIF coax cable. Why do other brands (Lynx, Chord) double this? I don't understand. 1.

jonmarsh Posted February 20, 2010 Share Posted February 20, 2010 in order to support quad rate SPDIF; others work fine with a single transmission. Some pro equipment will support both. Link to comment
The Computer Audiophile Posted February 20, 2010 Share Posted February 20, 2010 Some devices like the Peachtree components allow a very jittery device to connect via the second S/PDIF input. The sound quality is slightly lessened because of this greater tolerance but at least one has the option. Founder of Audiophile Style | My Audio Systems Link to comment
Matias Posted February 21, 2010 Author Share Posted February 21, 2010 But what is quad rate SPDIF? When is it used? 1. WiiM Pro - Mola Mola Makua - Apollon NCx500+SS2590 - March Audio Sointuva AWG 2.

The Computer Audiophile Posted February 21, 2010 Share Posted February 21, 2010 Quad rate usually refers to sample rates 176.4 and 192 kHz. Founder of Audiophile Style | My Audio Systems Link to comment
Matias Posted February 21, 2010 Author Share Posted February 21, 2010 Well, then Jon did not answer my question: why do some brands offer up to 24/192 (including quad rate 176 and 192) in a single cable, and others don't? 1.

Audio_ELF Posted February 21, 2010 Share Posted February 21, 2010 Matlas... I would say the answer to "why do some manufacturer support 24/192 via single wire and some require dual wire?" is like asking why some use Firewire and others use USB and still others stick with SPDIF - a combination of testing and phillosophy to give best results. Also SPDIF used to be spec'd at only 96k but manufacturers have pushed the spec. to allow 24/192 in more recent years. Using higher rate oversingle wire **may** result in higher jitter and therefore lower quality. Eloise Eloise --- ...in my opinion / experience... While I agree "Everything may matter" working out what actually affects the sound is a trickier thing. And I agree "Trust your ears" but equally don't allow them to fool you - trust them with a bit of skepticism. keep your mind open... But mind your brain doesn't fall out. Link to comment
