Goldmund's $700K Amplifier: Engineering Marvel or Luxury Excess?
The amplifier needs time to safely power down.
Mark
Why does an amplifier need to cost this much? Couldn't you get 90 percent of the performance for a tenth of the price?
Mimi
Probably, yes. But this isn't about getting 90 percent. It's about what happens in that final 10 percent—the ability to control a speaker driver with absolute authority, to deliver power instantly when the music demands it, to do all of that without introducing noise or heat into the signal path.
Mark
So it's not really about volume, then.
Mimi
Not at all. The power is there so the amplifier never has to catch up. It's always ready. That's a different thing entirely from being loud.
Mark
The two-storey design seems like an unusual choice. Why not just make it wider or deeper?
Mimi
Because the power supply and the amplification stage need to be apart. They generate different kinds of noise—electrical noise, heat. Sitting them next to each other would mean they're constantly interfering with each other. By separating them vertically, each gets its own environment.
Mark
And the price? Does the Swiss manufacturing really account for half a million dollars?
Mimi
It's part of it. But you're also paying for precision machining, custom transformers, the engineering time to solve problems most amplifiers never face. And yes, you're paying for the fact that very few people will ever buy one. The cost per unit is higher when you're making them in small batches in Geneva.
Mark
If someone actually bought this, what would they hear that they couldn't hear from something cheaper?
Mimi
Honesty. The ability to hear what's actually on the recording without the amplifier imposing its own character. Control. The speakers doing exactly what they're asked to do, not fighting back against the amplifier. That's what you're paying for.
El Pulso
- A single amplifier costs as much as a house in most cities, and you need two just to hear music in stereo — the entry price for this level of listening is AUD$1.4 million before a single speaker is connected.
- Each unit weighs 360 kilograms and stands nearly 1.4 metres tall, demanding trained technicians, lifting equipment, and a dedicated AC power line just to get it operational.
- The two-storey architecture physically separates raw electrical power from delicate audio circuitry, solving the interference and heat problems that haunt lesser amplifiers through sheer mechanical ambition.
- With 1,560 watts into 8 ohms and a damping factor of 900, the engineering isn't chasing volume — it's chasing control, the ability to grip a speaker driver with authority when music becomes complex.
- Swiss manufacture, precision-machined aluminium panels, custom transformers, and a six-and-a-half-minute controlled shutdown process all compound into a price that is enormous but, in its own logic, not entirely mysterious.
In a Geneva workshop, a half-million-dollar amplifier waits for the rare few who measure devotion to music not in hours listened but in millions spent. Goldmund's TELOS 9800 represents one of those curious human artifacts that sits at the intersection of engineering obsession and extreme wealth — a 360-kilogram monument to the idea that sound, pursued far enough, becomes something close to philosophy. At AUD$1.4 million for a stereo pair, it asks not whether the price is reasonable, but whether the pursuit of perfection has a ceiling at all.
A half-million dollars per unit. That is where Goldmund's TELOS 9800 begins — and it doesn't work alone. A stereo pair costs AUD$1.4 million before speakers or source equipment enter the conversation. Each amplifier weighs 360 kilograms, stands nearly 1.4 metres tall, and requires at least two trained technicians with proper lifting equipment to install. It is, in every sense, a commitment.
The amplifier's two-storey form is not aesthetic indulgence. The lower half houses the power supply; the upper half handles amplification. By physically separating these functions, Goldmund isolates the noise and heat of raw power delivery from the circuitry shaping the audio signal. French industrial designer Cécile Barani was brought in to ensure this functional architecture could also inhabit a living room with some grace — a thin gold accent marking the divide between the two halves.
Inside, a system called Controlled Energy Management works alongside a high-capacity capacitor bank, custom transformers, and a new generation of MOSFET output devices to deliver power quickly when speakers demand sudden surges. A SoftStart system brings everything online gradually. The result is 1,560 watts RMS into 8 ohms — numbers that aren't really about loudness. A damping factor of 900 at 1 kilohertz measures how firmly the amplifier commands a speaker driver after moving it, keeping complex music under control rather than simply making it louder.
Cooling is handled by the massive aluminium structure itself — no fans, no introduced noise, just natural convection through fins and 15-millimetre panels. Gold-plated copper terminals appear where conductivity demands it, though some of that gold is simply the visual language of a half-million-dollar object. Everything is conceived and assembled in Geneva, where specialist low-volume manufacturing compounds the cost of every precision-machined component.
Ownership carries its own rituals. Each unit needs a dedicated AC power line. Switching one off initiates a controlled discharge lasting roughly six and a half minutes. By the time all of this is absorbed, the price feels less arbitrary — though something still resists full explanation. Ultimately, the TELOS 9800 exists for a very small group of people who have long since stopped asking whether seven figures for a stereo pair makes sense.
A half-million-dollar amplifier sits in a Geneva workshop, waiting for someone wealthy enough to buy it. Goldmund's TELOS 9800 costs USD$500,000 per unit—around AUD$700,000—and it doesn't work alone. You need two of them to hear music in stereo. A matched pair runs AUD$1.4 million before you've connected a single speaker or chosen what to play. Each weighs 360 kilograms. Installation requires at least two trained technicians with proper lifting equipment, the kind of detail that matters when you're moving a tower of precision-engineered aluminium that stands taller than most people.
The amplifier's physical presence announces its ambition. It rises 1.367 metres, a two-storey structure of machined metal and cooling fins, with a thin gold accent running through its middle. That vertical split isn't decorative. The lower half houses the power supply—the electrical reservoir that feeds the amplifier above. By keeping these two functions physically separated, Goldmund isolates the noise and heat generated by raw power delivery from the delicate circuitry that shapes the audio signal. The arrangement is functional, but it required collaboration with French industrial designer Cécile Barani to make it something a person might actually want occupying a substantial corner of their living room.
What justifies the price begins with what's inside. Goldmund engineered a system called Controlled Energy Management, paired with a high-capacity capacitor bank that holds electrical energy in reserve for the moments when speakers demand sudden surges of power. Custom transformers and a new generation of MOSFET output devices release that power quickly, preventing the amplifier from lagging behind the music's demands. A SoftStart system brings all this hardware online gradually rather than flooding the electrical system with full load at startup. The result is 1,560 watts RMS into 8 ohms, climbing to 4,180 watts RMS into 1.4 ohms—numbers that sound impressive until you understand they're not really about volume. The reserves exist so the amplifier can grip difficult speaker drivers with authority, keeping them under control when the music gets complex. The damping factor of 900 at 1 kilohertz into 8 ohms measures how firmly the amplifier can command a speaker driver after moving it forward or backward to produce sound. These aren't specifications chasing the biggest number on a spec sheet; they're engineering choices made to serve the music.
The chassis itself is part of the cooling strategy. Rather than relying on fans—which would introduce noise—Goldmund uses the enormous aluminium structure and its fins to dissipate heat through natural convection. The metal enclosure also shields the electronics from interference. The company specifies 15-millimetre aluminium panels and a 40-millimetre radiator chassis. Gold-plated copper terminals and screws appear where conductivity matters, though some of that gold is admittedly there because a half-million-dollar amplifier is permitted to look expensive. Everything is conceived, engineered, and assembled in Switzerland, specifically in Geneva, where specialist low-volume manufacturing carries a cost that compounds with each precision-machined component.
Owning one of these amplifiers means accepting certain demands. Goldmund recommends giving each unit its own dedicated AC power line. Connections include XLR and RCA inputs, S/PDIF input and output, and Goldmund 4B and binding-post speaker connections. When you switch one off, the internal power supply enters a controlled discharge process that takes approximately six and a half minutes—the amplifier needs time to safely power down. By the time you've absorbed all of this, the price becomes less mysterious. It's enormous, mechanically elaborate, packed with specialized power hardware, and built in Switzerland at the highest end of audio engineering. Yet even after accounting for the engineering, the materials, and the labour, there remains something that defies neat explanation: how 360 kilograms of aluminium, custom transformers, capacitors, and Swiss precision somehow add up to half a million dollars. The answer, ultimately, is that this amplifier exists for a very small group of people who don't need to ask whether a stereo pair costing seven figures makes sense.
