Thanks for all your responses, loving the humor, I went to a proper HiFi store that actually sell my SVS speakers along with brands like Crown, Rotel, Paradigm, Krix, NAD & Denon "Down in Aus SVS are sold through retailers".
The way he tried to explain it was the difference between horsepower and torque........
Then went on to say a HiFi amp "Gets there quicker" with "power on tap" "for example if you're driving uphill in a 4 cylinder car and you put your foot down you'll get there but no as fast as if you had a V8............
I should have also said he's selling both the Crown amp i'm looking for and has a old demo Rotel for sale....
