A Conversation with Definitive Expert Gary on Octave Audio

On January 29th, we invite you to experience Octave the way we do at Definitive. An intimate listening event dedicated to what modern tube amplification can deliver when warmth, power, and precision exist together. Before the event, Definitive Expert Gary sat down to reflect on his experiences with Octave, from the first time he heard it in our Reference Room to why it continues to deliver goosebumps today. His insights capture exactly why Octave has become such an important part of how we listen.

There are moments in this business that reset your expectations. Moments when something you thought you understood suddenly reveals a deeper layer. For Definitive Expert Gary, that moment came the first time he heard an Octave tube amplifier.

“It was here at Definitive,” Gary recalls. “In our Reference Audio room, driving a pair of Wilson Sasha V’s.”

What he expected was familiar. What he heard was not.

When Harmonics Meet Control

Tube amplification has long been associated with harmonic richness and tonal beauty. That part showed up immediately. Instruments felt complete, textured, alive in a way that’s difficult to describe until you hear it yourself.

What surprised Gary was everything else.

“What stood out was the grip,” he says. “Solid-state-like control on the Sasha V’s. Nothing slow. Nothing soft. Nothing imprecise.”

That balance—harmonic beauty paired with authority and control—is where Octave separates itself. It’s not about trading accuracy for warmth. It’s about delivering both at once.

Why Tubes Still Matter

Gary has heard just about everything. So why do tube amplifiers still matter today?

“Because great tube amplifiers make music easy to connect with,” he explains. “They invite you in. You lose yourself in the performance. That matters now, and I can’t imagine a time when it won’t.”

For Gary, tubes aren’t about looking backward. They’re about emotional accessibility. About removing barriers between the listener and the music.

“If there’s ever a time when that doesn’t matter,” he adds with a smile, “I don’t want to be part of it.”

Not Nostalgia. Engineering.

One of the biggest misconceptions about tube amplification is that it’s fragile, finicky, or stuck in the past. Octave challenges that idea head-on.

“These are modern designs,” Gary says. “Auto-bias circuitry, robust protection against power issues, tube failures, overdrive. They’re incredibly stable and reliable.”

Octave preamplifiers use external power supply transformers to keep noise away from sensitive audio circuitry, resulting in what Gary describes as one of the lowest noise floors he’s ever heard from tube electronics. The modular design allows clients to configure inputs and outputs to match their system, rather than forcing compromises.

Power amplifiers can be expanded with external energy storage units, increasing performance without increasing chassis size. Output tube flexibility allows listeners to tailor sound and power by simply swapping tubes and listening.

And then there are the transformers.

“Octave began as a custom transformer winding company,” Gary explains. “And honestly, in a tube amplifier, the transformers are everything. I’m convinced that’s a big part of their secret sauce.”

What Tube Sound Really Means

So how does Gary describe tube sound to someone who’s never experienced it properly?

“A harmonically complete presentation,” he says. “A spacious soundstage. And dynamics that feel far more powerful than the amplifier’s rated output would suggest.”

It’s not about softness or romance. It’s about scale, realism, and energy that feels natural rather than forced.

Music That Reveals Itself

When demonstrating Octave, Gary avoids audiophile clichés.

“I use music my clients already love,” he says. “Because they’ll hear it differently.”

Two of his personal favorites on an Octave system are Juan Garcia Esquivel’s More of Other Worlds, Other Sounds and Jimmy Smith’s The Cat. Familiar records become new experiences, not because the system is drawing attention to itself, but because it disappears.

Goosebumps, Delivered Consistently

At Definitive, we talk a lot about goosebumps. Octave delivers them often.

“Unless the recording is especially poor,” Gary says, “what you get is a very engaging, lifelike performance happening right in your room.”

That consistency is what matters. Not a single wow moment, but repeated emotional connection.

What We Hope You Take Away

After hearing Octave at Definitive, Gary hopes people leave with something deeper than admiration for the gear.

“I hope they rediscover that deep connection to music,” he says. “That feeling that something meaningful has been shared between you and the artists. That it’s more than notes. More than sound.”

That’s the heart of Octave.
And it’s why it belongs at Definitive.

Because when music communicates, everything else fades away.
