The Heaven 11 Story


A Quest for Musical Truth | Old School meets New School

Our journey began with a simple mission: unite the warm, articulate character of vintage analog sound with the precision and power of modern engineering. We sought to achieve this through the careful pairing of a first-rate tube preamp with an audiophile-grade Class D amplifier—a combination that proved far more challenging than we ever anticipated.

The Spark of Inspiration

Heaven 11 was founded by Itai Azerad, an award-winning industrial designer:

“It started innocently enough. I bought a cottage and needed a new stereo.

There’s a moment most serious music lovers know. You hear something: a system, a room, a recording. And suddenly everything you’ve been listening to at home sounds wrong. Not bad, exactly. Just thin. Like a photograph of a place you’ve actually been.

That moment hit me the day I hooked up a new amplifier at my cottage. The sound was revelatory: texture, detail, a sense that the music had come alive in a way I hadn’t experienced in years. And then came the other feeling: twenty years of listening to what now felt like complete garbage. My home-theatre system hadn’t just been underperforming —it had been quietly robbing me.

My brother came over that same evening. We sat and listened for fifteen minutes before he quipped, “Yeah, sounds great, but I would never put that in my living room.”

That was the lightbulb moment.

He was right. The amp was a slab of uninspired folded metal. And once you surrounded it with the rest —DAC, phonostage, the tangle of cables connecting it all— the whole setup looked like a mess you’d want to hide, not something meant to bring music to life. A far cry from the stereos we grew up with. Brushed metal faces. Beautifully machined knobs. Glowing panels and dancing VU meters. Those objects had presence. They were meant to be admired, even coveted —altars for the ritual of music.

I’ve spent my career as an industrial designer, and one thing I’ve always believed is that objects communicate. Through shape, material, proportion, and detail, they tell you what they are and why they matter. Every micro-expression adds up. When all those signals point in the same direction, an object feels coherent. It feels right.

Somewhere around the mid-1980s, stereo equipment lost that coherence. It became bland sheet-metal boxes: functional, yes, but visually and musically lifeless. So lifeless that people started hiding their systems behind credenza doors. Out of sight, out of mind. And we’ve been making that devil’s bargain ever since —trading away too much with home theatre, soundbars, and Bluetooth speakers in the name of practicality, lower cost, smaller size, easier living.

If the mainstream had given up on sound, the audiophile world had given up on everything else. Bulky separates that weighed as much as furniture, labyrinthine setups, price tags that climbed into the absurd —all in pursuit of specs and micro-differences that had no bearing on whether the music actually moved you. Somewhere along the way, the point of all of it —the music— became secondary to the gear.

It never made sense to me. Music is arguably one of humanity’s greatest inventions. It deserves better than a choice between too little and too much.

“If I’m going to invest years of my life into this,” I told myself, “the world does not need another mediocre product.” It couldn’t just look the part. It had to sound as good as it looked —even better.

That’s when I met Denis Rozon, an engineer who had spent a lifetime working in hifi and tube amplification. Denis had a line he liked: “Everything about tubes is a con: they’re hot, fickle, expensive. The only pro is the sound.” That one pro is why tubes are still around today. Later, as the project grew more complex, Sylvain Savard came on as lead engineer, someone who understood both the old world and the new, and had the patience to make them speak to each other.

The challenge I gave them was deceptively simple: build an amplifier that was musically engaging, easy to use, and cost-effective to build. Not a machine designed to impress on a spec sheet, but one built for actual musical pleasure. For the experience of sitting down at the end of the day and feeling something.

Instead of cutting corners on the physical product, we stripped away the features that didn’t matter. We ignored vanity specs. We focused on the primary use case: stereo music, presented as it should be: without boosted bass or sizzling highs, without artificial tricks. Just music, delivered in a way that feels natural, emotional, and true to the artist’s intent.

We explored every technology with an open mind. Tubes, for all their measurable flaws, had that elusive quality of musical engagement. Class D, while sometimes criticized for sounding cold or glassy, could deliver remarkable performance in a compact and efficient form when paired properly with a tube front end. The more we worked, the clearer the goal became: fuse these two seemingly opposing technologies into something genuinely modern. A hybrid architecture that kept the warmth and emotional directness of tubes while bringing the control and efficiency that modern listening demands.

There were dead ends. A lot of them. But even through the failures, something kept pulling us forward —the sound we’d hear on a good day, when everything lined up. That sound became the target. Everything else had to earn its place.

Our first product, Billie, came directly out of that thinking. A hybrid integrated amplifier: tube front end, Class D output stage. Designed to bring warmth and precision together without compromise. Designed to sit in your living room like it belongs there. Not IN the credenza, but ON the credenza. The kind of object that invites you to stay and listen.

That idea became Heaven 11. Not an exercise in retro styling or audiophile nostalgia, but a response to a real gap: the growing distance between what music can be and what most of us are actually hearing at home. We think that gap is worth closing. We think the experience of listening and connecting to music is worth protecting.

That standard guides everything we design and build —right here in Montreal, where the whole thing started.”
