I use the sub filter on my Cambridge 640P because it works really well by blocking speaker pumping with no difference I can hear...tried an experiment: I put my cat in front of a speaker and switched the filter off to see if it would kill him...he survived...damn.
Phono-pre: subsonic filter on or off ?
I currently have mine set to on. Does this mean I'm rolling off some bass and perhaps not getting the full bass slam I should ? What do most of you do that have phono pre's with subsonic filters...on or off ? Thank in advance.
