the audio signal does not pass thru the coil (inductor) of the relay and so very little damage is done to the signal..... transistors do quite a bit of audible damage.

but then why doesn't an amplifier produce a huge amount of noise? i thought that most amplifiers used transistors in them. but ok. i think i get the idea, use relays if i can, transistors only for other signals.

The idea is this...

If you use a remote soft start circuit, you can use a transistor to trigger this. Use relays for the power supply rails to minimize heat and relays for the signal input switching / output protection etc just use transistors (BJT or FET) when you need a buffer, gain stage etc where transistors can not be avoided.
