What's the best way to hear multichannel sound? I've heard arguments on both sides of these two formats. Has anyone seen any definitive research on which one sounds better?
In the audiophile world, coax cable is widely considered to be superior to TOSLink. With very revealing components, TOSLink sounds brighter and less accurate. Bits are bits, but there are audible differences. The same is true with digital transports whose sole purpose is to read the digital bitstream from a disc and transfer the bits to an outboard DAC. Keeping the DAC and cables the same and switching only the transports, there are still audible differences. Go figure.Originally posted by TommyC
As for the wire, I use both and havent really noticed a difference in sound quality. Then again I dont use a high-end receiver or speakers.
The crux of the problem is a phenomenon called jitter which refers to small timing errors that can be introduced as the digital bitstream is read off the disc and transported through various processing stages on both the source component and the receiving component. The word clock that cranks out bits in quick succession as tiny electrical pulses can drift by several tens or hundreds of picoseconds between clock periods. The explanation is more complicated than this, but the result is that jitter produces undesirable audible effects. Jitter cannot be completely eliminated, but it can be significantly reduced. Apparently, coaxial connections offer more flexibility in controlling jitter.Originally posted by legion
It's a bit of a long explaination...
If the music you hear sounds bright or exhibits other audible effects compared with a CD transport or any other reference system you might have (I have connected several transports to my Theta ProBasic IIIa DAC and readily noticed audible differences), consider adding a standalone de-jitter device (Theta Digital or Monarch Audio among others) and listening for any improvement. De-jitter devices lock onto the incoming bitstream in all the usual ways (PLL circuits), but construct a new bitstream that is re-clocked using very accurate crystal oscillators and other components. De-jitter devices cost about $250 and are easily inserted between the source and receiving components. On the other hand, many mid- to high-end DACs today have built-in de-jitter capability.Originally posted by carletonmusic
I've been a professional musician all my life so I definitely do hear the smallest details of sound reproduction.

So what about the "quality" of the Digital Coaxial Cable or TosLink cable. Is the Monster cable that's thick and pretty going to make that much of a difference if the source material is digital?
