Streaming amplifier In development
Pick your speakers, shape your sound, and hear your room the way it was meant to be heard.
01 One box, every source
Streamer, DAC, amplifier and input switch, folded into one — every digital path handled bit-perfect. Nine ways in, and two ways out: your main speakers, and a reference line output for everything else.
Honest by default, natural reproduction — it stamps no house sound on your music. But when you want to shape it, the control is yours: 11 bands of parametric EQ per channel, allowing you to tune your sound around your world. Choose the speakers you fall for, tune them to exactly what you love, and change your mind as often as you like.

02 Where it started
The project began the day a simple soundbar could no longer carry the show.
Understanding sound means understanding how air moves, and that means understanding that everything matters: the cabinet’s volume, its material, its size, its shape, even its position in front of you. Try to take your home setup a step further and do the math, and you will soon find that “compact” solutions simply can’t reproduce the sound you’re after. That is not a concept; that is what physics says.
That is how the idea was born: the convenience of a compact system, in a build that doesn’t choose the speakers for you, and that is physically capable of delivering the sound you want.
Also, I want to keep the brain and the voice apart, so each can change without touching the other. If a speaker fails, you should only have to replace that speaker, with everything else staying as you left it. When you want more, you should be able to add a subwoofer or move to a different pair whenever you like. And because the brain runs on firmware, I want every update to keep improving what you already own.
03 Inside
Every part is drawn from scratch: the schematics and circuit boards in KiCad, the enclosure and its inner structure in FreeCAD. A Raspberry Pi Compute Module 3+ running embedded Linux, a Digital Audio Interface Transceiver and a Bluetooth 5.1 HiFi audio module feed a Class-D stage through a programmable DSP.
04 The power stage
The main output is built on the Texas Instruments TAS3251 — a Class-D amplifier with an on-board DSP, running at a fixed 36 V rail. The figures below are its rated capability.

05 The line output
A Burr-Brown DirectPath stereo DAC feeds a dedicated line-level output: a second pair of speakers, an active subwoofer, another amplifier or a recorder. It is ground-centred, so there are no coupling capacitors in the path and no turn-on thump, and it holds its performance into loads down to 1 kΩ.
06 What it will become
Brahma is a foundation, not a finished thing. Building from the silicon up means nothing is fixed — and the same idea is already taking new shapes.
Planned
When the room outgrows the stage.
Sometimes the founding brahma builds a stage that’s too small for its audience. A bigger room, a bigger crowd, a bigger appetite for sound — same soul, same features, but with real muscle behind it. Everything you love about brahma, scaled up in power to fill the spaces the original was never asked to. It’s on the way.
Planned
Respect for what came before.
We know we’re new here. Great sound existed long before brahma, and we respect the machines that made it — beautiful amplifiers, warm and characterful, that time quietly set aside when the world went digital and left them without a modern way in. VARANA gives them that way in: all of brahma’s flexibility — every source, every stream, every input, and the freedom to tune and shape it with the same DSP — delivered cleanly as a reference line-out to the amplifier you already cherish. Your grandfather’s amp, rediscovered, fed by a modern brain — the past, playing today’s music, on its own terms.
Planned
The same world, up close.
Same flexibility. Same open, honest signal. Same freedom to choose and tune. Only now it’s built to drive your headphones, not your room. MAUN brings the whole brahma philosophy to the intimacy of a great pair of cans — every input, every stream, reproduced with the same care, poured straight into your ears.
