I totally agrre with Jwaugh. The Merlins are very nice speakers and very difficult to beat at its price range, but the Kharmas are a very special thing matched with Tenor (I haven't heard them with Joule Electra).
I own a pair of Tenor 75wi that have been working well with the Merlins for more than one year, BUT, when a tried the Kharma CRM 3.2F in my room, I felt in love inmediately and inevitably: bigger and more coherent soundstage, deeper and tighter bass (I owned the Merlins without BAM), and overall the famous and unknown for me until that moment "timbral accuracy". The textures of all the instruments are unbelievable, specially the strings in classical music. Tenor plus Kharma represents the more involving musical experience I have experienced.
Merlins are great, with very good service, but Kharmas are, at least matched with Tenor, in another league IMO.
Good luck
