For tube amps consider the Cayin TA-30 (30 wpc push pull EL34, $900) or Decware Torii (12 wpc, SET sound, EL34, $1500). Both are well built. BTW the Torii was plenty loud enough for my speakers that use Fostex F200A drivers that are about 6 dB less efficient.
For solid state consider the Channel Island Audio chip amp monoblocks with passive pre-amp (40 wpc, $1250 plus interconnects) or a Scott Nixon chip amp integrated (40 wpc, cost should be around $700). Both allow for two inputs, the CIA appears to be the best built and offers a trial period. (Chip amps are said to work well with efficient single driver speakers.)
These speakers are efficient enough to allow use with SET amps as well (after all, that's what they were created to be used with).
