I have a choice between a A51 Halo amplifier (250W *5 channels at 8 ohm, peak amp = 60) and a Reference 200.5 amplifier (200w*5 channels at 8 ohm, peak amp =75A) to drive my B&W 703 and DS-7 surrounds and a HTM7 center channel. Which should i choose?

Hi Amperage is more important than wattage. Amperage is the measurement of the .amount of an electric current An amplifier needs a large power supply. With out current (amps) we would not have any power (watts) .Power (watts) = voltage x current.(amps)

Rms is misleading.It only gives part of the story.
I think I read somewhere on the web,that a sine wave is
generated and then measured-hardly 'real world' stuff.
Hope you find this bit helpful-can you compare them side by
side?On flat response/(neutral setting)- Does one sound too shrill or too bassy? It has to make good,clean power.
Does the amp/speakers go loud WITHOUT hurting your ears?
Are you still able to talk, and still be able to understood,with a
little difficulty?
Are you able to listen at high levels without the speaker cones folding up, or the speaker protection cutting in?
They say to trust your ears-but I think this is still
partly a 'learnt' thing.Or at least take a friend who
might have an idea.
I was at 'the Goodguys' store the other night,and the salesman-had this thing well overdriven,the sub sounded
like it was struggling-it had a horrible ringing(?)sound.
It must have had been clipping.
Stupid salesman-overdriving to get a sale.
I would pity the poor neighbours,if it was bought
and driven at that level all the time!
I think people have to respect and learn the limitations of their audio gear/amps and speakers-
which doesnt happen often enough.

Ask for a receiver with High Current amplifiers. A receiver with high current amps at 90 watts will sound much cleaner and more powerful than a standard current amp at 100 watts or more.
