First, let me state that listening to speakers has been a hobby of mine for decades. Moreover, once upon a time, I was a part-owner of a speaker company that failed.
That said, my criteria for suggesting a speaker manufacturer in my response is that I have heard more than one model (if said company makes multiple models) and every time I have been delighted/amazed by the overall quality of the sound reproduced. So, here goes — in alphabetical order: Clarisys Audio; Dutch & Dutch; and Rockport Technologies. They are all radically different from each other, and none will disappoint. Unfortunately, none are cheap, but ut the price to value ratio of Dutch & Dutch are noteworthy.
