Three of these four computer-audio finalists include an MM phono stage. CXA81 Mk II needs preamplified turntable audio.
3 matching models from 4 checkedBest for this need
Our pick
Yamaha A-S801 is a straightforward starting point for supported computer USB and an appropriate MM turntable without another phono box. Choose R-N800A when the household also needs network music after the computer leaves. Denon PMA-1700NE adds a compatible MC option, while CXA81 Mk II suits an existing phono stage and a clearly documented headphone handoff.
A-S801 combines USB-B computer audio with MM phono. Verify the exact computer and driver support. It has no built-in network player or HDMI ARC, and private listening needs a speaker-selector and subwoofer check. Follow the volume warning when changing direct mode after using loudness attenuation.
Choose an amplifier for computer USB audio and records. Compare phono integration, network playback after the laptop leaves and the late-night headphone reset.

What matters in practice
Choose around the sources that stay in the room and the settings the next session needs.
The USB-B inputs on these four finalists accept supported computer audio. A storage socket on another streaming amplifier does a different job, as does Yamaha’s power-only DC OUT. Identify the actual port, computer operating system, cable and current driver support before buying. A familiar connector shape does not prove compatibility, and a direct USB DAC still depends on a working computer source.
R-N800A includes MusicCast and AirPlay, so supported network music does not need the USB computer to remain beside the system. The other finalists require an appropriate source for that separate job. If the laptop leaves every evening or belongs to one household member, decide how the next person will start music. An existing streamer may already solve it, in which case replacing it with an integrated version is not automatically a useful upgrade.
A-S801 and R-N800A provide MM phono. PMA-1700NE also provides a fixed-load MC setting, subject to the exact cartridge’s requirements. CXA81 Mk II needs preamplified line audio. If the turntable already has a suitable stage, Cambridge does not necessarily add another box. If it does not, include that stage and wiring. Avoid choosing a built-in MC label without checking output and recommended loading.
On PMA-1700NE, Analog Mode disconnects USB communication. Returning to computer playback may need the documented reconnection or software recovery steps. That matters if someone listens to records at night and another person expects the same computer audio route to work immediately in the morning. Leave the mode off when that continuity is more useful. The feature can be valid for a dedicated analog session without being helpful in every mixed household workflow.
CXA81 Mk II explicitly mutes speakers, PRE OUT and SUB when headphones are inserted. A-S801’s complete subwoofer behavior is not established by the checked manual, so test the actual installation. R-N800A wired headphone notes name speakers and PRE OUT, while its separate sub output still deserves a check. Denon’s normal wired headphone route mutes speakers. Keep unknown details visible rather than borrowing behavior from another model with a similar name.
4 options
Yamaha, A-S801BL
Combines a computer USB audio input with MM phono, making it useful where a desk and record setup share one pair of passive speakers. It avoids a separate USB DAC for a supported computer. It still needs another device for network streaming, and headphone use deserves a check of the speaker selector and connected subwoofer.
Winner whenA-S801 combines USB-B computer audio with MM phono. Verify the exact computer and driver support. It has no built-in network player or HDMI ARC, and private listening needs a speaker-selector and subwoofer check. Follow the volume warning when changing direct mode after using loudness attenuation.
No HDMI ARC or built-in Wi-Fi streaming.
Yamaha, R-N800ABL
Brings computer USB audio, MM vinyl and MusicCast into one full-size system, with YPAO for a room where speaker placement is constrained. It can reduce the need for separate streaming and DAC boxes. The TV still needs optical or another supported audio route because R-N800A has no HDMI connection.
Choose instead whenMusicCast, AirPlay and YPAO should work alongside computer USB and MM vinyl. It has no HDMI. Bluetooth transmission leaves speakers playing and excludes AirPlay, while Pure Direct changes available correction and transmission behavior.
No HDMI ARC for the TV remote routine.
Denon, PMA1700NE
Pairs a computer USB DAC with MM/MC phono for a system that changes from desk audio to records. That combination can avoid two external source boxes. Leave Analog Mode off if uninterrupted computer reconnection is important, because turning it on disconnects USB communication and may create a restart step later.
Choose instead whenComputer USB and a compatible MM or MC cartridge should connect directly. Check cartridge output and loading. Analog Mode interrupts USB communication and may require a recovery step before the next computer session. No HEOS or HDMI is built in.
No built-in HEOS or HDMI ARC.

Cambridge Audio, CXA81 Mk II
A mixed digital and analog amplifier for someone using a computer, Bluetooth device or a source with balanced XLR outputs. Plugging in headphones mutes the speakers, pre-out and sub, a useful detail when the shared room changes to private listening. Vinyl still needs a separate phono stage or a turntable with one built in.
Choose instead whenPhono amplification is already handled and headphone insertion should explicitly mute speakers, pre-out and sub. It has computer USB and no built-in phono stage. The USB port is not direct flash-drive playback, and there is no HDMI ARC.
No built-in phono stage, HDMI ARC or network streaming.
