Should all hi def cables audio and video 75ohms?

[RH Customs]

I was looking at some different cables, and found that most tech engineers recommend 75ohm for hi def cables. Meaning both the connector and cable rating. I was looking around and there really are not to many manufacturers that offer a "True 75 ohm" cable. Does it really matter for home A/V?

It would depend on the distance you are laking about. The cables used are 75 ohms with some +/- to it, no 75.000 that I know of. Many of the RCA connectors are an issue though. But, usually it is of no concern.

Isnt 75ohms and industry standard by which all equipment is manufactured too?

That is what I thought, but after reading several articles, I noticed most manufacturers don't give the ohm rating.

If you wanna do it right, you should try to make 75-ohm cables.

Yes, but, always a but
Audio and short distances means not that critical
