Hello Joe.
 >> Some of the amps are phase inverting, some are not phase inverting.
 >> How loudspeakers must be connected to phase-inverting amp?
 >> Should "live" (red) wire of loudspeaker go to "ground" (black)
 >> terminal of amp, or everything should be connected straight? Gregory
 JB> For what application?  Your message is kinda vague ...
   Just for general music and voice listening. For first look phasing
of all sound path should be noninverting, with a purpose to reproduce
ambient conditions (at the recording site) corectly and exactly.
   IMHO every manufacturer is obliged
to inform if his equipement is phase-inverting and suggest ways to reverse.
   Quite right You are, not everything is clear for me in this question :-)))
