M9000: 9000 Watt – Monoblock Amplifier

The upgraded M9000 features our 7th generation M Series high-current amplifier circuit, refined with new enhancements focused on extended reliability, durability, and improved transient response. These upgrades provide greater control and stability under load for improved sound quality revealed through tight, solid, and shocking low-end punch. We further beefed up internal high current pathways on the PCBs in multiple ways. Redesigned high stress sections to use through-hole, higher power components Increased the power supply current capacity by over 30% Added 2 toroidal transformers, making it a six-pack Upgraded to larger, higher current power supply Mosfets and increased the total from 16 to 24 Increased the total number of output section Mosfets from 8 to 12 Increased the overall heat sink length for the most demanding thermal applications Stronger power supply increases transient impact delivery These upgrades allow the M9000 high current, half bridge amplifier to run with lower internal stress during tortuous demo sessions while driving difficult and demanding impedance curves. The M9000’s chassis features DD Audio’s exclusive High Volume Air Circulation (HVAC) heat management system. The mass and intelligent fin design of the super heavy-duty extruded aluminum heatsink constantly conducts heat away from internal components. An internal brushless fan pulls in cooler air through an elevated bottom panel and end panel vents to maximize air flow.
