Please recommend a high-powered SS amp

I'm surprised that you find the Plinius to be clipping. It's known to be a very gutsy amp. What Proac speakers are you using with it? Maybe the limitation lies there. If you want very high volumes, perhaps look into different types of speakers (such as horns).

If it's just a higher-powered amp you seek on a budget, I'd look into the old Carver Lightspeed amps.

Way back when I had Proac monitors, too. I think that your speakers are becoming congested at higher volumes, rather than your amp clipping. Monitors speakers in general probably aren't your best choice if the goal is loud music. For that, look into horns, or at least decent-sized floorstanders.

That's my guess, anyway.
