10ht,
Your amplifiers will be suitable matches for most of the speakers on your list but not for the Nenuphar.  This very unique speaker will not perform at its potential with low output impedance/high damping factor speakers. This speaker is designed to work (at its best) with high output impedance amplifiers with little or no NFB (Negative feedback) thus low damping factor. . The 6 Moons review amplifier comparisons with the Nenuphar clearly demonstrated this. The Nenuphar is virtually the antithesis of a speaker such as the Raidho  you're also interested in. These two speakers have very different amplifier requirements (And quite likely very different sonic presentations).

Hi 10ht,
I agree with those who say that more specific information (room size, preferred listeningvolume level, amplifier etc.) will likely result in more meaningful recommendations. What sonic characteristics do you most value? Given you enjoy jazz (so do I) the Cube Audio Nenuphar is definitely a prime candidate. From what I have learned from a friend/Gon member who owns them (10" model) they are spectacularly good sounding speakers. Amplifier compatibility will vary greatly amongst your list of speakers.
