Thank you so much Joe...and everyone for their kind thoughts and comments. I know I'll have them for the long haul. I think, with the Phase Linears and Onix I have obtained with the help and expertise of the people on this Forum, that I finally have the best, and probably last audio components I'll ever need. It's been a fun journey from the time I joined the Forum. Got to love this hobby!
They are 1984 models.
Some people have said 1985 and later are not as good? But, I have no idea if there are differences or not. I also have heard that the SpeakerLab K is actually a better design than the original Klipsch design. I have no idea..
