N.P.I. What is it?

Listen to your MONO recordings with all channels off except for one and tell me what you hear. No Phantom Image.

Try it, it's right for the format.

B.T.W. In my previous thread MC told me I was so ignorant he could write a whole book about it. His problem was he didn't know where to start!!

Back on topic, I am enjoying "Essential Delta Blues" a compilation on Not New Music (2009). And damn if polarity doesn't make a difference - but a switch every other track? I guess it's eglitarian. I like the boost from the corner speaker (R in my case).

N.P.I. Give it a try and report here.
