PKN XE10000 (2 * 5000W+ @4R) is a very cost effective solution to drive two of 8R/2500W speakers per side. If you want even more headroom H8-18002U (2* 10000W @2R) would be the best ever but that is expensive and not so common yet.

i find it odd people moan about amp weight when wanting to run 4 or 8 cabs that weight 100kg each ?? obvz I expect it on big touring applications where they need minimum rack space and maximum output but not on smaller things

The general misconception is that everybody thinks that the amp will drive a resistive load (all amps parameters stated by resisitive load) however the speakers are reactive. It means that the output current are usually OUT of phase with the coil driving Voltage! Why it so important? Most(if not ALL) analog amplifiers have a type of output stage which NOT allows to sink or source large current when the output devices see large momentary Voltage drop, especially when the output Voltage nears Zero but the load current still large.. Big big surprise than pretty large analog amplifier could be forced entering to output power dissipation protection of its power devices to prevent momentary overheating of junction layers if the current shift is unfortunate angle.. Here comes the advantage of modern switching amplifiers: with proper construction a good switching amp can deliver its max. output current at ANY output Voltage :-) So while a large analog amp loosing control movement of Volice coils due activated momentary output dissipation (UxI) protection, maybe even a smaller switching amp could work better.

...surely that's a topology problem... not a PSU problem.

I’m also interested in how powerful of an amp is recommended for 2x TLW3000

No. Class AB amp shave almost the worst conversion efficiency ~ 50-60% maximum. Also plagued by the problem I have mentioned above^. Class-D ( high frequency switching ) amps could have efficiency above 85% while very few reaches ~ 95% or more. Linear (50/60HZ transformer) and poor switching power supplies without PFC are equally bad due their mains current distortion originated from 'peak rectification', which end sometimes as bad as they consumes 5X or 10X of the output power. For example a 1000W SMPS(without PFC) or toroidal transformer would needs 4.3A average (6.2A peak) from the mains if the power factor would be correct (1.0) but unfortunately - due peak rectification - usually pulls out 50 or 100A peaks with very narrow conducting angle which is bad for the mains, generators and could create dangerous over Voltage spikes on the opposite phases. Learn and understand why good power factor are so important.
