Solid state, Valvet Audio A4 mono blocks. Pure class A 55watt into 8 ohms/90 w at 4 ohms.
Tube, Line Magnetic 805ia class A SET 48 watts.
Both of these amplifiers would in my opinion easily drive your 8 ohm impedance speakers. Caution, if your listening space is modest the 805 tube will generate heat.
Either will contribute to providing beautiful sound quality given the make up of your Audio system. . I believe that the Gryphon recommendation from George is a good option as well.
P.S.
Luxman 590 AX MK II pure class A. Intergrated but I believe that the preamplifier section can be bypassed.
