*shrug* seems like you're stuck in the past, no wonder you can't deal with active.
Something like a fusion plate amp would get the job done and provide much cleaner output.
As for low THD, maybe you can back that up with measurements? Nothing I've seen indicates that. THD is fairly high. IMD is worse. Dynamics will be compressed from the low power output.
Not trying to crap on your choices, just bringing some actual facts to the discussion.
Here are Aleph 3 measurements...
Pass Aleph 3, THD+noise vs frequency at (from top to bottom at 100Hz): 4W into 2 ohms, 2W into 4 ohms, 1W into 8 ohms, and 2.83V into simulated speaker load (right channel dashed).
Pass Aleph 3, HF intermodulation spectrum, DC-22kHz, 19+20kHz at 26.7W into 4 ohms (linear frequency scale).
Pass Aleph 3, distortion (%) vs output power into (from bottom to top at 40W): 8 ohms, 4 ohms, and 2 ohms.
