I started with Magneplanar MG-1Bs in 1980 and in the last 26 years have upgraded through MG-IIBs, MG-IIIa's, detoured into Apogees and Martin Logans, and finally settled into a pair of Tympani IVa's.
For amps, I started with a Hafler DH-200, upgraded to a DH-220 and a DH-500, tried an Adcom GFA 555 and now have a Mark Levinson 23.5.
They can certainly gobble up the power, and I am thinking now about upgrading to even more powerful monoblocks.
Nonetheless, I would agree that it depends on your musical taste and your room.
I imagine in a small room, playing not the most dynamic or bass heavy music that even modest amounts of tube power would sound great.
Good luck.
