Now here's a crazy idea:

ATX 2009 Corsair CX 400 Watts Corsair CX 400 Watts

Kingwin LZP-550 Lazer Platinum 550 W

Anandtech - Seasonic Platinum Series 860W - Platinum without the Fuss

PC power supplies aren't as good as regulated linear supplies, but the best of them aren't bad at all, and I wondered if I could fit a PC supply into a surround processor:

Its rather overkill, as processors & DACs only use a few tens of watts, but ripple is usually lowest at low load levels, and PC supplies are hardly expensive in the context of four-figure processors. Linear supplies are better, but they do generate more heat, and the transformers hum a bit, so now I'm wondering if a high-quality PC supply would improve on the stock supply (50 - 100 mV noise & ripple), while avoiding some of the noise, vibration and heat issues. A nice compromise in the middle, maybe?
