Hi,
Over the past 35 years I have had over 300 different speaker models through my reference listening room, models, not brands. I currently have 3 different sets of speakers that I play with. Once I find a set of speakers that works better with my reference equipment I keep that set and eliminate one of the sets of speakers that I consider not as good a match to my set up. My preference for the past few years has been high efficiency speakers that are matched up well to the proper amplifier.
Cheers,
