Best sounding amp for 12-30V DC?

[xrk971]

Another option is TDA7297, aka the lunch money amp. You can get the $5 version and upgrade a few capacitors. Use a 12v brick for a PSU and it sounds decent. You can go hog wild and use a fancy board like the one made by OS Destroyer.

I second that, tda7297 is a very good sounding amplifier. But don't cross the 17vDC power supply limit.

This may, or may not, be what you require:

ZOUDIO AIO438 - Z O U D I O

His previous product is well regarded by a number of users here on DIYAudio:

ZOUDIO AIO4CH: 4-channel amplifier with DSP and Bluetooth

The engineer/designer responsible (Lukteveld/Jesse) is very active here also, offering support, advice and answering questions.

I have a Zuodio amplifier. But i havent tested it enough to conclude yet.

Got a similar setup, minidsp 2x4 and two Aiyima A04 (TPA3251) amps for powering my speakers. Although I´m swapping amps often and will exchange them in the future, they work fine with 24V.
As mentioned the TPA3255 will provide 50W/8Ohm at 30V.

Haven´t calculated the idle dissipation of a TPA3255 but would reckon it´s around 1-2W. Going lower in voltage (if you don´t need the power) will also reduce that dissipation a little if you want to save some more.
24V for a BTL TPA3255 amplifier will yield around 25W/8Ohm.

I´d definitely recommend class-d amps when being solar powered and listening loudly.

You should talk about all those nice looking things in the background😉
I see 4 huge horns and 2 subs?

It is my home system. Acoustic Elegance TD18H+ subwoofer. Inlow Sound 100 Hz frontloaded horn with EMS LB7 midwoofer. JBL 2384 horn with JBL 2451 Truextent beryllium diaphragm. Groundsound DSP/preamp. Hypex and Anaview DIY amplifiers. Sony toploader CD. Al lot of RPG professional room treatment products.

This is the off grid battery powered amplifier i think i am most happy with so far:

Hifimediy T3 mono TK2050 amp, Jantzen caps - Hifime Audio

It is my home system.

Thanks for the info/picture. Now I see where you are coming from
and why you like to listen loud!
Unfortunately I never heard anything similar to such an impressive system but I hope I will and I bet my *** it sounds as well as it looks.
That´s quite a luxurious and tastefully built (wo)man-cave!

Those amp modules look like a good choice. Don´t know the chip but I see proper coupling caps, heatsinking and power reserve if your spoiled ears want it real loud ;-)

The Hifimedy amplifiers have Tripath 2050 chip

Noe i have hum in the Hifimedy amp??


Kingrex T-Amp with TPA2020 sounds also very good:
