Solid state class AB, 150wpc, impeccable build and sonics to match. runs cold to just a tad warm, but has treble fidelity i've never heard from AB. has proven a wonderful combo with speakers such as Wilson Sasha 2s and now Magico S7s, never running out of power and always musical and inviting.
the ideal match for the C-900U preamp, and the combo is a last stop for not-outrageous sums.
