DeKay, a bit scary, every item you listed I have owned, all only once, but one could say I owned the Large Advents twice since I had two pairs stacked with the top one upside down...to get the tweeters close together which helped the image. A "burned into my mind" memory was the first time I heard the Magneplaner 1D speakers..the three panel models.....think my friend was using a Crown Pre and Power amplification and likely an early direct drive Dual turntable with either a Shure V-15 or and ADC XLM....all with first gen Monster interconnects and speaker wire....and it sounded....ah.. let’s see...FINE, VERY FINE.
(and a P.S. Since the store I worked at was an Advent dealer I had the chance to hear the "double Advents" that Advent people had set up at C.E.S. and the top pair was upside down)....w/the tweeters close together.
The store I worked at was in Iowa City, named The Stereo Shop, which later was sold and re-named Audio Odyssey.
