Apologies up front if this a dumb question! Have just bought a set of the eggs to go with my soon to arrive plasma (Pioneer 434) and AV amp (Pioneer 501). Have plugged 2 of the eggs into my existing stereo amp, and to be honest, they do not sound very good at all. In fact so poor I am tempted to box them up and return them. Sound is very 'tinny'. Have also tried adding the sub driven from the tape line out but this produces a headache inducing thump (I know they are a pain to setup so have lots of tweaking to do). My question is this: Do they need to be driven by a proper AV amp to get the best out of them? Is there something in the output of AV amps that boosts certain frequencies etc? Have seen so many rave reviews and awards on these speakers that I can't beleive they are as bad as they currently sound! Thanks.
