My current line of thinking is using a something like the TPS61080DRC at 600kHz boosting the batt voltage to say 6V, then linear regs to take it down to +5V (TPS71701DCK) and +2.5V (TPS79901DDC).

Free QuoteThe power supply dissipation is a bit different. Usually the power supply for a power amp is not regulated. So you mainly have to consider the peak current demands on the bridge rectifiers and transformer. A regulated supply is a different matter. 36 volts (plus and minus) means 162 watts peak, which is 81 watts RMS.
Free QuoteHigh power car audio amplifiers use DC to DC converters to generate the rail voltages needed - a single 12V supply can not provide a high power output. Low power car amps running on 12 directly, operate in bridge mode into a 4 ohm speaker to produce approx. 18W max!

TNT-Audio has a very good article on amp power supply that describes various designs. IT explains the purpose of RC network and small value caps as well as purpose of dual rectifiers. The diagram you show correspond to fig 4/diagram 4 in the article.
*Up to twice the runtime is possible compared with eight AA NiMH batteries with 2,450 mAh capacity. Actual runtime and performance can vary with the conditions of use. Products that support the Rechargeable Amp Power Pack will be listed here as they become available. Unless noted, the AC adaptor included with the amplifier can be used for charging.
So ultimately, the primary characteristic needed is stability, all things considered, the power supply should have no effect on the amplified audio by way of fluctuations in DC potential available to the amplifier circuitry. Practical power supplies for HiFi amplifiers could be linear, switch mode or (less practically) batteries.
From a physical design standpoint, the power supply should be located in such a way that it has the least opportunity to induce hum into the amplifier circuit particularly in an integrated amplifier where there is a preamp handling low level signals (like a phono input).
Audio, Audio, Audio! In any well designed HiFi amplifier, there will be a power supply whose job is to convert the AC mains supply voltage to a DC voltage. The power supply must also be able to provide a reserve of power to cope with any sharp transients in current demand without suffering a decrease in voltage output.
