Having owned a Audiostore and experimentation ,I feel the quality of the source is
most important , speakers a close 2nd why ? For the quality of the source is what makes the audio signal ,good or bad , once it goes to the next component it is just that ,it cannot be improved upon. Even if it was the finest speaker ever made.
if the instruments tone ,and Soundstage is not there then the Loudspeaker cannot
reproduce what it does not have . The Loudspeaker is though right behind the source to finalize the creation of the original signal, From Start to Finish.
