Checked 3 days agoDirect source1 evidence itemAmplifier architecture and ownership branch
high-value high-current Class AB with USB DAC
Checked 3 days agoOur synthesis3 evidence itemsExact amplifier and purchase boundary
The exact A-S801, remote and mains lead are retained; computer driver, source cables, network streamer, Bluetooth adapter, loudspeakers, turntable cartridge and subwoofer are separate
Checked 3 days agoOur synthesis3 evidence itemsAmplifier topology and signal path
Yamaha's analogue Class AB output stage and ToP-ART chassis retain independent source, tone, Pure Direct and CD Direct paths. Digital sources pass through the onboard DAC, while network transport remains external
Checked 3 days agoOur synthesis3 evidence itemsContinuous power, impedance and load boundary
The FTC basis is 100 watts per channel into 8 ohms from 20 Hz to 20 kHz at 0.019 percent THD. Published dynamic 6-, 4- and 2-ohm figures are short-term values, not continuous ratings, and the rear impedance selector plus A/B combinations must follow the manual exactly
Checked 3 days agoDirect source3 evidence itemsAnalogue inputs, preamp and bypass paths
RCA line inputs, tape-style line output, MM phono and main-zone volume are provided. There is no balanced input or power-amplifier bypass, and fixed recording output must not be used as variable level control
Checked 3 days agoOur synthesis2 evidence itemsDigital, television, Bluetooth and network path
Optical and coaxial S/PDIF accept bounded PCM rates, while USB-B supports higher-rate PCM and DSD through the documented computer path. There is no Ethernet, Wi-Fi, HDMI or native service streaming, and Windows or macOS USB support depends on current drivers
Checked 3 days agoOur synthesis3 evidence itemsPhono, cartridge and headphone boundary
The phono input is fixed moving-magnet gain and loading; low-output moving-coil cartridges need a separate stage or transformer. The 1/4-inch headphone output mutes or redirects speakers as documented and still requires exposure control
Checked 3 days agoOur synthesis3 evidence itemsSpeaker terminals, subwoofer and output boundary
Speaker A and B terminals and a mono subwoofer output are physical. Simultaneous A+B use changes the allowable per-speaker impedance, and the subwoofer output does not provide modern automatic bass management or room calibration
Checked 3 days agoOur synthesis2 evidence itemsRoom correction, tone, control and bypass
Bass, treble, loudness, balance, Pure Direct and CD Direct change the path in different ways. There is no measurement correction, app, programmable crossover or per-source automatic level matching
Checked 3 days agoOur synthesis3 evidence itemsMains power, heat, ventilation and placement
The 26.7-pound 120-volt chassis needs full ventilation and stable support. High-current use, low impedance and simultaneous speaker pairs increase heat; protective shutdown is a fault response rather than extra continuous power
Checked 3 days agoOur synthesis3 evidence itemsSoftware, service license, account and privacy
Analogue, S/PDIF and core controls are offline. USB DAC use adds Yamaha or operating-system driver support, while any external streamer introduces separate service accounts, subscriptions, network permissions and privacy terms
Checked 3 days agoOur synthesis3 evidence itemsFirmware, warranty, parts and regional service
Yamaha retains the U.S. manual, legacy and current USB drivers and regional service. Test both speaker banks, every analogue and digital input, USB enumeration, phono, headphones and protection behavior during the return period
Checked 3 days agoOur synthesis3 evidence itemsHearing, electrical, tube and installation safety
Amplifier and headphone capability are not safe listening levels. Use the exact supported mains supply and speaker load, power down before rewiring, keep ventilation clear, keep liquids away, control cable strain and exposure time and never open or service energized equipment. Tube models retain lethal voltage and burn risk after shutdown and require their exact manual and competent service.
Checked 3 days agoOur synthesis3 evidence itemsSound, compatibility, reliability and outcome boundary
No amplifier topology, wattage, impedance label, protection circuit, DAC, network service, phono stage, room correction, cable, review, owner report, warranty or service plan guarantees sound quality, speaker compatibility, safe listening level, reliability, uptime, software continuity, resale or any listening, health, safety or commercial outcome.
Checked 3 days agoOur synthesis5 evidence itemsCurrent verdict
The traditional high-value DAC referenceA-S801 is defended for buyers wanting substantial conventional power, MM phono and computer DAC capability while keeping network streaming and room correction outside the amplifier.
