Y2015 AV8802 <Challenge to reach Premium H-Fi quality Complete Redesign of the Hi-fi grade amplifier
Analog section of the amplifier is protected from high frequency noise (also improved jitter)
Derived enhanced measured and subjected sonic improvements well above the AV8801 levels.
Hi-speed output amplifier Upgrades Using the same grade as the Newest Hi-Fi (Slew-rate: over
100V/μsec or an order of magnitude performance gain.)
Doubled reserved power supply capacitance using audiophile grade components.
Evolution of Marantz AV Pre-Amplifier
Split Pre and Power True Hi-Fi Quality Noise reduction Chassis Separation
New technologies
Full discrete current feedback with HDAM-SA2
Jitter reduction Efforts. DSD Compatibility.
Transformer with OFC winding/
New developed main Multi Layer Boards
New Improved DAC / AKM AK4490
Current technologies (continuing)
Independent PCB analogue output circuit
(HDAM-Pure Lines )
3 pieces chassis and dual mounting stay with copper plated chassis

x 7 times Hi-speed (41.7V/μsec) than AV8801
More higher quality XLR output : mounted same circuit for Invert amp
