I should have kept my Dynaco A25 speakers...just the right size, nice cabinet, I could have experimented with drivers and x-over. Oh well. 1970s nostalgia maybe.
You are invited on a "trip down memory lane".
This thread is, of course, mainly hyperbole (or less kindly B.S.). But that said, what is an item from your sound system over the course of your journey that you would most want to have back? I have sold some that I, likely, should not have. Mine would be the CJ ART pre-amp and the Magnepan MG-20....a distant 3rd and mostly nostalgia would be the Dahlquist DQ-10 speakers.
