Hi. I've read somewhere or another, and probably at multiple places, that digital coax cable length can affect the signal quality due to signal reflection, standing waves or some other explanation. From a long time ago I am familiar with but forgetful about signal reflection and/or ringing in RF (radio frequency) coax cables. The big difference is that RF is in a different frequency range where it may matter more. Then we've got the inherent mismatch in 75ohm S/PDIF coax due to the RCA connector, maybe that contributes to the problem but I don't know. Now from what I recall it was recommended to either have very short (<9") or moderately long (3ft+) digital coax cables but nothing in between. So, while the theory might be sound like many other audio(phile) theories it may not matter in the real world or may be a misapplication of a theory that is true in other cases - I can see manufacturers wanting to upsell a certain length of cable to longer 3ft+ lengths than what's an impractical <9" length In other words 'Don't get 1ft or 2ft cables.' So, is this true in any way that would affect a S/PDIF signal, has anyone tried different lengths of the same cable, or what other solid information do people know about this topic?
