Digital and Analogue XLR Cables - Is There a Difference?

@lordmelton let us know if sounds different. I suspect it will. 

After doing quite a bit of Googling I found that most studios use 110 Ohm cables for analogue and digital. They don't use 75 Ohm cables at all.

There does seem to be a consensus that 75 Ohm cables can intrduce jitter in the digital domain but short runs are acceptable.

My cables are only 1.5 m. I will change to a high end 110 Ohm cable but at the moment my 75 Ohm cable sounds great,

Actually the spec for XLR cables is their characteristic impedance, which is 110 ohms for digital XLRs but can vary for analog XLRs. Characteristic impedance is the impedance presented by an infinitely long length of a uniform transmission line. A cable terminated with a load equal to the characteristic impedance will transfer all the energy to the load without any back reflections, which is crucial in digital signal transmission to minimize reflections and resultant jitter.

Hi Rick,

Well thanks for that. I always believed they were both 110 Ohms.

I've been using the analogue for digital XLR for many years and haven't experienced any problems.

XLR cables are balanced they have a pos, neg & ground.  The actual conductors vary according to brand and price point.  Analogue XLR cables are 75ohms while Digital are 110ohms.  The difference between analogue and digital is the resistance.
