I have owned both Spendors and JMR speakers. I've never owned Harbeths.
I traded in my Spendors after a few years because I found the sound a little boring.
The JMReynaud speakers - I've owned both floor standers and monitors - are much more dynamic and exciting. They have an amazing midrange and a very sweet high frequency range. They are not harsh or over analytic and are on the warm and rich side of the spectrum. I've auditioned similarly priced speakers in my home - Totems, NOLAs, Regas - no comparison. The JMRs are in another league and make beautiful beautiful music.
