Mdeblanc,
It is not a kit, I bought it from a dealer. Another thing you must be aware is that the speakers really need to burn to sound their best. So any comment before 500 hours is premature. What is funny the a/b test with the other speakers were done on brand new speakers. About the amplificarion, till now I drove them with three different amp, antique sound, an e otto integrated, an e quest monoblocks and tom evans lineer a, all produced very good results, but at the end I chose to keep my antique sounds (maybe again because the an amps i tried were not burned properly, that is burn in is a major issue with an than I know any other brand) But the main point is I see and experience no reason why they should not sound good with quality components.
