The Big Question About Simaudio’s Moon 491 Preamplifier and 461 Amplifier

In this episode of SoundStage! InSider, Doug Schneider visits Simaudio in Boucherville, Quebec, to get answers about the new Moon 491 network preamplifier and Moon 461 stereo amplifier directly from product director Dominique Poupart. The biggest question? Whether these new Compass Collection components are simply a Moon 371 split into two boxes — or something substantially more ambitious. Dominique explains why the answer is “far from it,” detailing the redesigned fully balanced preamp stage, upgraded dual-DAC architecture, dedicated headphone amplifier, more sophisticated phono stage, dual-mono amplifier topology, and higher-output MHP power-supply design. Doug also presses Dominique on the details audiophiles actually care about: moving-coil loading options, capacitance settings, rumble filtering, biamping capability, bridged-mono operation, output-transistor design, real-world power delivery, and whether the 491/461 combination truly delivers a meaningful performance step beyond the 371. If you’re interested in modern high-end streaming systems that combine compact form factors with serious engineering, this discussion goes deep into what Simaudio is trying to achieve with the expanding Compass Collection. #audiophile #stereo #hifi
