Default Low power consumption reference amp

I would like to build a studio/mixing setup on a small sailboat.

Everything will be running from 12-volt lead acid batteries, charged by solar. We don't have a lot of capacity, so I want the power consumption to be as frugal as possible.

Can anybody recommend a D or T amp that would be a good choice for running a pair of near-field monitors?

- 12v DC supply, obviously
- Best possible flat frequency response and low distortion
- Modest power output is fine

I see a few likely candidates out there such as Tripath TA-2020 or TA-2024 but was wondering if there is something else on your radar.

Thanks - !

Given the 12V SLA, you can expect about 10W @8Ohm of undistorted output power in BTL configuration . All suitable class-damps will give similar output power at given supply voltage an load impedance. You better look for low standby current consumption to extend battery life.
And for high efficient, water-proof speakers.

MaxAmp20 would be the preferred option. Second best would be the TPA3116 in 1SPW mode in my opinion.
