About 12 months ago I purchased a Samson PB10 from @sherpa_man ;
I haven't really used it to be honest, didn't get round to ordering extra cables.
I've been getting some hissssssssssssssssssssssssssssssssssssss from my speakers so I thought I would try it.
Feck Me. What a difference. They are totally silent. I'm almost imagining hissing because I was so used to it.
