Head-to-head
Marantz MODEL M1 vs WiiM Amp Ultra: AirPlay or a screen at the cabinet?
The short answer
Choose MODEL M1 when AirPlay 2 and HEOS are already part of the home. Choose Amp Ultra when a touchscreen, Google Cast and RoomFit matter more. Ultra has no AirPlay. Both need external phono amplification for a raw turntable and neither provides direct computer USB audio or a wired headphone socket. M1’s Dirac route involves paid extras.
Before you choose
The reasoning and the trade-offs
The best interface depends on where the next user starts
If someone reaches the cabinet without their phone, Ultra’s touchscreen provides supported local playback and source controls. If the household normally starts music through AirPlay from the sofa or another room, M1 preserves that path and Ultra removes it. Both can use a compatible TV’s HDMI control, subject to the television’s settings. Separate those three starting points before deciding which amplifier is easier. A bright local interface is useful only when it solves the handoff the people in the room actually make.
What this is based on
Several household users at different starting locations crossed with touchscreen, AirPlay and conditional TV control.

No AirPlay 2 or built-in phono stage despite the Ultra name.

The differences that matter

How we reached this conclusion
Several household users at different starting locations crossed with touchscreen, AirPlay and conditional TV control.
Room correction changes the setup project as well as the feature list
M1’s current manual includes a paid Dirac setup route, while Ultra offers RoomFit. For a room with fixed furniture, include the required license, microphone or supported measurement device and setup time before comparing those options. The M1 can remain the right choice for AirPlay even if you never buy Dirac. Ultra can be the more practical choice when RoomFit meets the intended adjustment and the household uses Cast. Neither name proves a better result in your room, and neither stops bass or voices travelling through a shared wall.
How we reached this conclusion
Fixed speaker placement and limited setup resources crossed with the different calibration prerequisites. No measured room outcome or sound-isolation claim.
A smaller amplifier does not necessarily mean fewer boxes for records and work
Both accept line-level analog sound, so a raw cartridge output still needs suitable phono amplification. Neither accepts direct computer audio through its USB storage connector, and neither has a wired headphone jack. A buyer trying to replace a desk DAC, phono stage and headphone amp with one compact purchase should therefore reconsider the connection plan. These models work neatly when the sources already provide the right signals. The useful comparison is the complete system left on the shelf after buying, not just the dimensions of the new amplifier.
How we reached this conclusion
A shared work, vinyl and private-listening surface crossed with three independent input/output limits. No assumption that every source requires a separate box.

Meaningful differences
What changes the fit
| What changes | Marantz MODEL M1 | WiiM Amp Ultra | Why it matters |
|---|---|---|---|
| Music handoff | AirPlay 2 and HEOS. | Google Cast, no AirPlay 2. | The existing household habit can be the decisive compatibility check. |
| Local operation | No touchscreen, compatible TV control through ARC/eARC. | 3.5-inch touchscreen and ARC. | A screen helps at the box while TV control helps from the sofa. |
| Room adjustment | Current manual includes a paid Dirac route. | RoomFit supported. | Compare the complete calibration plan, not just the feature name. |
| Records and computer | Line input and storage USB, no phono or PC USB audio. | Line input and storage/output USB, no phono or PC USB audio. | Neither is automatically the whole system for a desk and raw-output turntable. |
What you give up
Every choice has a cost
If you choose Marantz MODEL M1
- Include any Dirac license and measurement equipment rather than assuming it is ready in the box.
If you choose WiiM Amp Ultra
- An Apple user may need a different starting app or source route.
Recommendation switch
The decision flips if...
The current Apple and HEOS routine must remain
Choose Marantz MODEL M1. M1 preserves it.
A local touchscreen and Cast matter more than AirPlay
Choose WiiM Amp Ultra. Ultra fits that operating routine.
What matters in practice
Before you choose
The amplifier with the visible screen may be easier beside the cabinet while the other preserves the family’s existing Apple routine.
What this comparison cannot tell you
- No subjective sound comparison adopted from forum reports.
- More watts do not establish a better speaker match.
- Firmware and paid correction options may change.
