US$265 is a fair-to-good asking price for an MRX 300, and it looks a bit below the typical used market rather than a true steal. Recent asking comps cluster around roughly US$250–US$400, with some cleaner or better-bundled examples landing near US$300+; that puts this listing on the attractive side if it’s fully working and complete.
The MRX 300 is still respected for solid Anthem amplification and a more serious, high-current sound than many mass-market receivers of its era, so it remains a worthwhile buy for a straightforward 7.1 theater setup. The real upside is value: if it includes the remote, mic, and is free of protection-mode or HDMI issues, this could be a very satisfying grab at US$265.

Anthem traces its roots to the 1990s in Canada, emerging from the acclaimed Sonic Frontiers, a brand celebrated for its no-compromise high-fidelity components crafted by dedicated engineers and audiophiles. In 1998, Paradigm acquired Sonic Frontiers, including Anthem, marking a pivotal shift toward innovative home theater electronics while preserving the pursuit of pure, unadulterated sound. This heritage of passion fused with scientific precision defines Anthem's enduring Canadian legacy.
The brand excels in premium amplification and processing, renowned for AV receivers like the MRX series, high-end processors such as the AVM line, and MCA power amplifiers. These products integrate proprietary technologies, including Anthem Room Correction (ARC), the pioneering room optimization system born from advanced research. While not venturing into speakers, turntables, DACs, headphones, or cables, Anthem's focus on electronics delivers reference-level performance tailored for discerning home theater and hi-fi setups.
Anthem holds a commanding position in the high-end market, topping charts as the leading brand for home theater preamps/processors with 30% share and ranking fourth in AV receivers at 31%. Repurchased in 2019 by Paradigm co-founder Scott Bagby and his brother John, restoring original stewardship, Anthem embodies premium Canadian engineering—reliable, innovative, and free of excess—for knowledgeable buyers seeking world-class audio without compromise.
