Guess I'm in the minority here. I have used one religiously on nearly every side of every record for the past 30 years. A Zerostat for most of that period, and the Milty equivalent in the last couple of years.
I have no idea how necessary or unnecessary it is, not having done any controlled experiments. But it would figure to be more likely to be necessary for someone like me who listens to a lot of wide dynamic range classical music (containing lots of low level passages), than for someone who listens mostly to dynamically compressed rock music (where the volume level will tend to always be much higher than the noise floor of the record surface).
