Re: [SlimDevices: Audiophiles] External DAC on Transporter: best output option
FWIW, SoX uses 32 bit integer internally when passing data between each process step you specify. Each process step can internally use a higher resolution, some calculations use 64 bit float. SoX can also finally output 32 bit PCM as WAV, if you want.

"32 bit PCM" most often means 32-bit floating point (that has a resolution of 23 bits), not 32-bit fixed point. Anyway, 32-bit fixed point would not make any sense, as there aren't any practical DACs with linearity and SNR that would exceed 24 bits. And, of course, good luck finding a commercial recording with a SNR exceeding 16 bits. "To try to judge the real from the false will always be hard.

Re: [SlimDevices: Audiophiles] External DAC on Transporter: best output option
Hi all! I've finally stumbled across Mr Adams himself discussing using an external DAC to a Transporter, & his theoretical justification for the best way to do it... The discussion comes in a Slim Devices forum thread where Mr Adams is (very patiently!) trying to explain to someone who has splashed out a king's ransom on dcs high-end gear why it is the -*wrong*- approach to use the word clock output from an externally boxed dcs "super clock", here: http://forums.slimdevices.com/archive/index.php/t-39770.html To justify his argument, Sean then goes on to reference the following theoretical exposition (by an Italian chap, in slightly shaky English - however the logic is quite clear): http://www.tnt-audio.com/clinica/diginterf2_e.html So there we have it at last. Sean put the word clock in on the Transporter so that the preferred "backwards" configuration of connection between transport & external DAC could be used. Note that the point of the word clock connection is to prevent clock *-drift-* not to eliminate jitter. It is made quite clear that the digital jitter will be increased by connectors, cabling & the physical distance between the clock & the DAC chip. However so long as the jitter does not become so severe as to affect the actual bit stream, this will not matter *-since the bit stream is re-clocked in the external DAC right next to the DAC chip -*if the "backwards" connection arrangement is used. So any increase in jitter up to that point will be totally eliminated. This "backwards" method of connection is precisely the way I have my Transporter connected to my Mytek Brooklyn DAC, with the 0.8ps jitter internal DAC clock (right next to the Sable 32 bit floating point DAC chips) acting as the master clock for the slaved Transporter. Of course back in 2008 Sean was still singing the praises of the fixed point 24 bit DAC chips inside the Transporter (which were famously marketed as "magic") & its 20ps jitter internal clock - but then there weren't any 32 bit DAC chips back then. I'm now starting to feel justified in my assertion that I'm getting superior audible output...
