Depends on the application and signal. It's probably good for 25' for a -10 consumer line level signal.

As you know, the longer the cable, the more likely it will have noise problems. If you need lengths of 50' or more, you better change to balanced lines using transformers or a direct box to a balanced input.

Always go balanced whenever possible dude.
In my facility 98% of all my patch is +4dBu balanced, I'd hate to hear what the noise floor would be like if that were not the case.

I have always suggested 20 - 25 feet as a maximum for unbalanced lines. Depending on the cable used, beyond this length interconductor capacitance begins to attenuate high frequencies.
