I own Bliss Hifi, a high-end audio boutique based in Minnesota. These Mola Mola Ossetra monoblock amplifiers are in on consignment from one of my clients. Single owner, just a few months old, and in like-new condition and perfect working order. The manufacturer’s warranty is transferable, with over 2.5 years of coverage remaining. The Ossetra began shipping only at the end of 2025, so a preowned pair is a rare find.

The amplifiers come with their flight cases and all original accessories.

Mola Mola amplifiers have always made a strong argument that the best Class D is not a compromise but simply a better way to build an amplifier, and the Ossetra is the clearest case the company has made yet. It is built on Bruno Putzeys’ Trajectum platform, with a new power supply and all-new discrete Class A input and gain stages, and the result is an amplifier with no sonic fingerprint of its own. The background is completely silent. Bass is gripped and articulate, even on difficult speakers, because the Ossetra’s output impedance is so low that the speaker simply cannot push back on it. The midrange is clean and finely resolved without any hint of the dryness or glare people sometimes associate with switching amplifiers. What you hear instead is speed, scale, and a sense of the amplifier stepping out of the way. Its gain is selectable, so it pairs cleanly with a Mola Mola Makua or Tambaqui and with third-party preamplifiers, and its half-width chassis takes up very little rack space for the power on tap. If you have been waiting for a pair of Ossetras to appear on the used market, this is likely to be the first, and it comes with the flight cases and the balance of the factory warranty.

Happy to answer any questions. Thanks for your consideration.

Check my stellar feedback and buy with confidence. This listing includes free insured shipping across the CONUS. As this is a passthrough sale that I am brokering on behalf of my client, I prefer to accept payments via PayPal F&F, Venmo Gift, or personal check, but this also gives you the opportunity to attain this at my lowest possible price. Credit card payments are also possible for a 3.1% convenience charge.

More about the amplifiers:
The Mola Mola Ossetra is a fully bridged, fully balanced Class D monoblock power amplifier designed in the Netherlands by Mola Mola, built on the company’s proprietary Trajectum amplifier technology developed by Bruno Putzeys. The Ossetra pairs a newly engineered power supply with a discrete Class A, DC-coupled input stage and all-new discrete Class A gain stages. Input stage distortion measures below roughly -150dB. The new power supply exceeds standard EMI requirements, lowers noise, and improves both dynamic and continuous output power, and new shunt voltage regulators are used throughout. The input is normally capacitor-free, with a capacitor added automatically at high signal levels to accommodate third-party preamplifiers. Power output is 350W into 8 ohms, 700W into 4 ohms, and 900W into 2 ohms. Gain is selectable at 22dB or 28dB. THD is below 0.003% at all frequencies and power levels, signal-to-noise ratio is 130dB, and bandwidth exceeds 100kHz. Output impedance is below 0.002 ohms, for a damping factor above 4,000. Balanced input impedance is 200k ohms. Connectivity includes selectable balanced XLR and unbalanced RCA inputs, two pairs of Furutech binding posts wired directly to the circuit board with Kubala-Sosna cable, and a 3.5mm trigger input. The chassis is Mola Mola’s half-width, wave-topped design. Dimensions: 200 x 110 x 335mm (7.9 x 4.3 x 13.2 inches, W x H x D, including speaker terminals). Weight: 7kg (15.4 lbs) each.
