Swiss high-end audio manufacturer Goldmund has unveiled the Telos 670 integrated amplifier, a 250-watt Class A/B beast with a built-in DAC that promises wide bandwidth, ultra-low distortion, and the sort of “effortless authority” usually reserved for Bond villains with mountain chalets. Throughout its history, Goldmund has never been the brand of choice for the everyday audiophile—it’s the audio equivalent of a Swiss watch wrapped in a tax shelter: technically brilliant, brutally exclusive, and priced so high that if you have to ask, you’re probably still making payments on your last integrated amp.
Goldmund claims the Telos 670 ensures “pure, uncompromised reproduction” even when pushed to its most demanding power levels—translation: it won’t break a sweat while your speakers beg for mercy. The result, according to the Swiss maestros, is an amplifier with excellent dynamics, razor-sharp spatial accuracy, and bass so precise it could probably file your taxes.
Of course, this is marketing-speak polished to within an inch of its life—but if past Goldmund designs are anything to go by, there’s just enough truth in it to make audiophiles sell a vital organ and pretend it was worth it. It’s less The Sound of Music and more The Hills Are Alive…with the Groans of Your Banker.
Connectivity, File Support, and Enough Aluminium to Build a Small Fortress
Around the back, the Telos 670 serves up single optical and coaxial inputs, five RCA analogue inputs, and a USB Type-B port. Its digital module handles PCM up to 32-bit/384kHz and DSD128—because anything less would be beneath the Swiss chalet crowd.
The aluminium enclosure doubles as a natural Faraday cage, shrugging off electromagnetic interference like it’s beneath its dignity. A 9mm casing and 30mm-thick radiator chassis pull heat away passively—because fans are for computers, not Swiss trophy amps. The mass-optimized structure and conic feet promise “rock-solid stability” while whisking vibrations away from the electronics, preserving sonic clarity across the entire frequency spectrum with all the solemnity of a Swiss banker counting gold bars.
The joint-free, precision-machined body, micro-blasted in grey aluminium, mixes structural integrity with a kind of “timeless elegance” that translates to: this block of metal looks expensive. A black finish is available upon request—though naturally, it comes with lead times, because exclusivity waits for no man.
The Goldmund Telos 670 is a high-end integrated amplifier built for those who consider “overkill” an understatement. Its power supply accommodates 115 V or 230 V mains (±15%), effortlessly driving 250 W per channel into 8 Ω (IEC 60065, 1/8 output) with Goldmund’s Class A/B Telos circuitry.
Distortion is practically invisible—THD+N clocks in under 0.08% from 20 Hz to 20 kHz at 30 Vrms output, intermodulation distortion below 0.02% unloaded, and the damping factor hits a tidy 600 at 1 kHz/8 Ω, giving speakers the sort of control usually reserved for Swiss watchmakers micromanaging gears. True RMS dynamic range of 100 dB keeps every delicate detail audible, though at a price that might have your accountant weeping in the Alps.
Connectivity is thoughtfully focused rather than flashy. The Telos 670 offers three digital inputs—USB (Audio Class 2.0, supporting PCM up to 32-bit/384 kHz and DSD64/DSD128 over PCM), Toslink optical, and coaxial S/PDIF RCA—alongside five analog RCA inputs.
That’s more than enough to accommodate your streaming source, CD transport, and DAC without overcomplicating the signal chain. There’s no phono stage, HDMI ARC/eARC, or headphone amplifier—because Goldmund knows that piling on features would ruin the understated Swiss bling.
Maximum input levels reach 1 Vrms for analogue and –6 dBFS for digital, while output before clipping hits 170 Vpp unloaded, with a maximum of 215 W per channel into 8 Ω at 1% THD. It’s connectivity that whispers exclusivity rather than shouting convenience.
The chassis is a feat of Swiss engineering and modesty-free excess: a joint-free, precision-machined aluminium enclosure measuring 44 × 16 × 39.5 cm (17.32 × 6.30 × 15.55 in) and weighing 24.5 kg (54 lb).
In short, the Telos 670 is a triumph of over-engineering, over-expenditure, and over-the-top Swiss bravado. It’s technically flawless, sonically commanding, and priced so high that Julie Andrews herself might spin on an Alpine hilltop, suddenly reconsidering The Sound of Music for a career in asset liquidation.
Assembling the Goldmund Dream: Telos 670, Eidos Streamer and Reference SACD Player and Speakers That Command Attention
Goldmund likes to keep things in the family, which makes pairing the Telos 670 with the Goldmund x Pink Faun Eidos Streamer a no-brainer. This first-ever collaboration with Dutch audio wizards Pink Faun marks Goldmund’s foray into the streaming world, combining cutting-edge digital tech with the sort of timeless design only the Swiss can pull off without making it look like a spaceship console.
The Eidos Streamer handles your local music library, integrates streaming services, and synchronizes playback across devices, all controllable through the Roon app—yes, that requires an active subscription, because nothing good in life comes free.
Access is simple across smartphones, tablets, and desktops, while internal storage tops out at a generous 8 TB. Streaming options cover TIDAL, Qobuz, and KKBOX, so you can indulge your audiophile tendencies without hauling a truckload of CDs up the Alps.
On the disc side, the Eidos Reference SACD keeps Goldmund’s hardware pedigree alive. Like its predecessor, it plays SACD, CD, CD-R/RW, and DVD-R/RW/+R/RW (audio data only), but now it’s capable of PCM up to 384 kHz and DSD512 when connected to a computer.
In short, it’s a Swiss-Dutch hybrid that ensures your music sounds as refined as your bank account is thin.
The final nail in your financial coffin? The Goldmund Rhea Passive Loudspeakers.
Goldmund’s obsession with precision shows in every detail of the Rhea Passive. The cabinets are assembled with invisible seams for a finish so flawless it practically glares at your lesser speakers, and each panel meets at a perfect 45° angle—because why settle for merely good when you can achieve obsessive perfection?
Wavy side panels catch the light like a tiny Alpine sunrise, adding depth and drama, while the dual-finish aluminum exterior—micro-blasted vertically, brushed horizontally—injects architectural elegance into any listening room. Standard is refined gray with black grids; black is optional, provided you survive the stock lottery. Art like this doesn’t come cheap—$108,000 USD for a pair, in fact.
Under the hood, the Rhea Passive is a three-way passive loudspeaker: a soft dome tweeter, a single 7-inch midrange, and a 12-inch woofer. Its sibling, the Theia Passive, upgrades to a four-way design with dual midrange drivers (4-inch and 6-inch) while keeping the same 12-inch woofer, smoothing transitions and improving resolution across the frequency spectrum.
Each Rhea cabinet weighs over 123 kg (271 lb) and sits with the sort of authority that could make a small sedan look nervous. Goldmund’s proprietary mechanical grounding system channels unwanted vibrations away from the cabinet, ensuring nothing interferes with pure, uncolored sound.
Frequency response is equally commanding: the Rhea spans 27 Hz to 25 kHz, delivering deep bass and extended highs, while the Theia pushes down to 20 Hz, reproducing full sub-bass impact without the need for external reinforcement.
The Bottom Line
The $36,250 USD Goldmund Telos 670 integrated amplifier delivers 250 W per channel in Class A/B, with a built-in DAC supporting PCM up to 32-bit/384 kHz and DSD128, ultra-low distortion, and precision Swiss engineering that keeps vibrations and EMI at bay.
Pair it with the Goldmund x Pink Faun Eidos Streamer, Eidos SACD player, and Rhea Passive speakers, and the system approaches $200,000 USD—before cables, turntable, phono preamp, or equipment stand. Every element reflects Goldmund’s obsession with engineering exactitude and high-end exclusivity, and the total price makes it clear this isn’t for the faint of wallet: even Powerball winners might flinch.
