I need some new leads for my microphones is there much difference in sound quality between leads or will the sound be the same with a cheap lead to a expensive one?
Dont want to spend aload of money on leads if there is no improvement in sound.
Leads meaning just the cable, right?

The biggest difference in quality that you'll notice is the cable's durability. So how well the connections are soldered, how thick the rubber insulation is, etc etc. A cheap one is just fine for home use. If you'll be moving them around a lot, gigging with them, etc, you might need to look at one more durable, but again, a cheap one should do fine.
it's all just coming back

it's all coming back to me
They will be gigged with we got 4 mikes two came with what i call guitar jack leads and the other two came with three pin leads (think there called that) the three pin ones seem to give better sound.
