Im currently using a pare of jbl HLS 620 and im thinking of replacing them with the synergy series from klipsch. i really liked the sound of the SF1 they sound great. but i need some postive reviews , and bad if there are any about these speakers. this is important since i really am not in a hurry to stash away the HLS620. so, do you think these klipsch sf1 are better then the JBL? or should i just stay with them? 10x..
