Amplifiers - depends how much clean power you need, where's the limit?

A streamer, on the other hand, has a single defined task that can be taken to notionally perfect, measured, and defined as such, for not a lot of money.
If they can't totally optimize the power supply in the actual device itself and still sell it for £13K and make a good profit, then they're in the wrong business.
But in fact they're in the right business as there's actually a market for £14K worth of add-on power supplies for £13K streamers, insane as that sounds.
