Would still like to hear from Louis, just what the wattage rating is for each driver. I know Louis avoids specifications like the plague, but maximum power (and output) would be useful is handled intelligently, and it would remove a cloud (at least in my mind) over his products. I know Omega is not for headbangers but live music can reach peaks of 105 dB, can Omega? In room, with two speakers, that can translate into needing 108 dB output at one meter. With the stated efficiencies that equates to needing 20 - 40 watts per channel to reach symphonic peak levels. And having a safety margin is always a good thing (in the case of solid state to avoid nasty/hard clipping that can melt speaker voice coils).
Traditionally:
Tubes provide their cleanest signal at low outputs (where most listen, especially with higher efficiency speakers) and solid state are cleanest at high outputs.
Tube amps had poor damping, meaning that speakers would suffer bass bloat (exaggerated, flabby, poorly controlled bass). But as very few high efficiency speakers can reach say 30 Hz and all amps (50 years all were tubes) were small, it was pretty much a mote point.
Nowadays both solid state and tube amps have generally gotten better in these regards. The ancient Decware Rachel I home auditioned on my single driver speakers (F3 = 25 Hz, 90 dB/w/m, 8 ohms) years ago sounded glorious but bloated badly, but no solid state amp has and neither did my Prima Luna Dialogue Premium integrated (tube).
