There are very very expensive 1.0 meter digital cables on the market. Either those designers lack the knowledge underpinning the 1.5 meter premise, they designed around it, or it's simply not true. Otherwise it would make sense for the lengths offered to start at 1.5 meters.
Digital cable length- SPDIF vs AES/EBU- 1.5 meter for either?
Some have postulated, with Steve Nugent at the forefront, that a digital cable between source and DAC should be 1.5 meters. The articles I've read nominally speak of 75 ohm SPDIF cables. Does the same length reccomendation hold true for a 110 ohm AES/EBU cable?
