I would venture a guess that a McCormack DNA 0.5 Rev. A or perhaps a pair of them would do wonders with the Extremas.
A friend of mine in Canada owned the Extremas for years (and recently sold them) had for a number of years powered them with a McCormack DNA-2 LAE(Limited Anniversary Edition) amp.
The DNA 0.5 is pretty legendary in stock form and a Rev A or Rev A Gold could put things over the top. In the right setup, a Rev A should sound like neither tube nor solid state, yet provide the best charactistics of both.
-IMO
