@reavesdc I've never had an issue. I asked Grok about Duets with 2ohms loads:
Key Performance Expectations with 2-Ohm Loads:
- Power and Current Handling: The Duets can deliver peak currents exceeding those of many traditional Class A/B amps in this power class, often estimated at 600W+ into 2 ohms based on their doubling pattern and GaN architecture. Reviewers note they "anchor perfect control of image and musical energy regardless of amplitude," even with speakers featuring complex impedance curves.
- Sound Quality: Expect retained transparency, speed, and SET-like warmth without compression or distortion. Bass remains tight and extended (no muddiness), mids gain lifelike body, and highs stay smooth and detailed. They excel with "difficult loads" like those with upper-bass impedance dips, outperforming conventional Class D designs in grip and effortlessness.
- Stability and Efficiency: No thermal issues or shutdowns, thanks to >94% efficiency and minimal heat generation. They're praised for driving "any demanding loudspeaker" with authority, similar to higher-end AGD models like the Solo (rated for >70A peaks into 4 ohms).
- Limitations: While robust for most high-end speakers, extremely reactive or phase-shifting loads below 2 ohms might push limits at ear-splitting volumes, but this is rare in home audio. They're not ideal for massive horns requiring 1,000W+ bursts, where the pricier Solo would shine.
In your high-end system, pairing Duets with 2-ohm-dipping speakers would likely yield punchy, fatigue-free playback—far better than amps that falter here. For confirmation, AGD offers in-home trials to test with your specific setup.
