You mention Jupiter in header, than Jensen in post. I've used variety of Jupiters over years, love both aluminum and copper. Haven't used Jensens since owning some Cary monoblocks many years ago. And to throw another J cap in, the Jantzens are nice at lower price point.
I too am interested in hearing comparisons to Odam as I've yet to try. Odams are interesting as realatively lower price point vs some, and more importantly, smaller size allows use where others can't fit. Reviews I've seen up to this point very positive.
