Marantz · CINEMA 30
Ready to buy
The retained reference is About $4,800 current direct reference. External amplification, correction licenses, dealer setup and rack planning remain part of the real installed price. Confirm the current configuration, included parts, support path, return terms and the work that must be preserved before ordering.
Current market
Each line carries its own check date because price, software, specifications, and product cycle do not age at the same speed.
External amplification, correction licenses, dealer setup and rack planning remain part of the real installed price. Confirm the checkout price and package before paying.
CINEMA 30 fits a premium eleven-channel build or thirteen-channel expansion where Marantz support, construction and interface are valued explicitly.

What changed
Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.
CINEMA 30 was checked against its manufacturer record, the current category collection and the nearest ownership alternatives.
Each amount stays tied to its source and capture date. Conflicting prices remain visible until the seller resolves them.

Owner experience
Owner discussion repeatedly returns to thirteen-channel expansion, software licensing and flagship service rather than specifications alone.
These are self-reported experiences from a changing mix of owners, conditions and software versions. They identify questions to test, not a failure rate.Owner threads repeatedly surface HDMI handshakes, firmware, room-correction workflow, heat, channel assignment and support experience; those reports are configuration-specific troubleshooting evidence, not population-level reliability data.
Document which channels the external amplifier will drive and purchase software only after confirming the license applies to this model and intended subwoofer topology.

Marantz identifies CINEMA 30 as an eleven-amplifier flagship Marantz receiver with 13.4-channel processing, seven HDMI inputs and four independent subwoofer outputs
About $4,800 current direct reference was retained from the current manufacturer or authorized-market record with package and availability qualifications kept visible.
Marantz publishes setup, compatibility or service material that makes this purchase boundary explicit: Processing thirteen speakers is not the same as powering them: a 13-channel layout needs external amplification, and the 140-watt figure is measured with two channels driven under the published 8-ohm test
A current independent specialty-retail collection exposes channel counts, HDMI connectivity, room-correction systems, authorized pricing and support while separating receivers with internal amplification from processor-only components.
Independent technical coverage keeps amplifier test conditions, channel loading, processing topology, thermal behavior and HDMI implementation visible instead of treating one headline wattage number as universal output.
Independent receiver reviews compare room correction, surround formats, ergonomics, connectivity and measured or observed system behavior while preserving the speaker, room and setup context around each conclusion.
Owner threads repeatedly surface HDMI handshakes, firmware, room-correction workflow, heat, channel assignment and support experience; those reports are configuration-specific troubleshooting evidence, not population-level reliability data.
CINEMA 40 represents the reference expandable nine-channel receiver branch at $3,800 current direct.
AVR-X6800H represents the expandable eleven-channel receiver branch at About $3,699 current U.S. reference.
The manufacturer record, current market collection, support material and independent category evidence were checked on August 16, 2026. The checkout package and regional support path still need verification. Owner reports are retained as bounded experience, not a reliability rate. Powered channels, processed channels, amplifier test conditions, room-correction entitlement and HDMI input and output counts are kept distinct. No record guarantees compatibility with a particular speaker, room, source, display, cable or firmware, and no listening-level statement is a safety guarantee.
