I need to connect an old yet very powerful Focusrite Saffire 24pro DPS to my machine and need to buy a new 2m firewire 800 to 400 cable. I tried to search Amazon and Google but cost is in range between < £1 up £24. I also searched for reviews on cables, some say firewire transfers a digital signal therefore distortions due to interference, yet other say even though we have "010101" in signal distortions still cause problems with detection of device, data may be transferred multiple times due to errors etc.
Do you think good quality of cables for audio and recording purposes matter? If someone also could give me a good brand to search for, I would be grateful.
