Please don't associate me with the ABXing that Arny finds makes his QSC USA series 'PA
amplifier' sound as good as the best of genuinely well-designed high-end audio.

I have listened to these QSC amps and I regard them as very 'agricultural' in their
performance. Even before listening, you could thow several technical brickbats at them
based on examination of the circuitry.

I have no trouble distinguishing such types - yet it's entirely explainable using
science too. No surprise to me I have to say !

Now - would you like to start again ?
