Millions of years ago I took a stab at making and selling mains conditioners for an existence - that stab only wounded me, but in the process of curing my intense commercial naivety, I discovered that some people prefer the sound of their system with bad mains - this being just one among the many other technically wrong things people do because they prefer the sound: all perfectly legit of course, since the enjoyment of music is subjective not objective…
The stupid fucking twats.
tl;dr - borrow before you buy, you may just prefer things as they are now.
PS: please don’t literally bin it, it appears to be mostly working, and someone somewhere may want it - you can always offer it up for a small donation to forum funds on ‘Spongers Corner’
