I have to second Mejames suggestion of the VTL 225 that are currently listed for $2200. The other VTL 225's listed for $999 may be bogus since I have not heard back from the seller after several attempts myself.Also they are still not marked as sold when the $999 is far below market value.
None the less the VTL 225 with the Ei KT90 tubes run in only full triode mode and matched with the efficiency of the ML Request will sound incredible. No need to worry about the low load of the ML's, This amp can handle it hansomely. The only issue you will face is the heat from the tubes, but beleive me, once your hear sound you may be willing to deal with it.
Good luck,
Jimmy
