I just acquired a used set of Morrison Audio speakers, Model 1.5 from 1993. A friend was over and had them in storage, felt I could put them to use as one of my main stereos is in a rather smallish room. The speakers I currently use are 1978 Genesis Physics Model 3's.
Interesting looking speakers, and very interesting sound. Instead of angling them towards a the listening spot a distance away and in the centre these sound the same pretty much wherever you stand or sit, which works better for the smaller room as you no longer need the chair further away.
I'm still playing various music (vinyl, CD, analogue radio) with them, but so far I find voices sound better, more natural. Most instruments sound good, more natural, and more detailed. I'm not taking advantage of the 4 terminals in the back, just the standard 2 channel.
