EverSolo Play CD Edition vs WiiM Amp Ultra: Two All-in-One Streaming Amplifiers Compared

Introduction

The EverSolo Play CD Edition and the WiiM Amp Ultra sit in the same small category of hi-fi gear: a single compact box that handles streaming, digital-to-analogue conversion and amplification, with no separate DAC or power amplifier required. The EverSolo adds one more thing on top of that, a CD player built into the chassis.

The two units are close enough in purpose that comparing them directly makes more sense than treating either one in isolation. They overlap on streaming and app control, and they diverge on price, power, build quality and the features each one leaves out.

The EverSolo is the more expensive and more heavily built of the two. The WiiM Amp Ultra retails for around $550, roughly $150 less, and puts its money into power output instead. What follows is a section-by-section look at where each unit earns its place.

How These Two All-in-One Units Compare

Both units cover the same basic job description, so the useful differences come down to a handful of questions. Which streaming services and casting protocols are supported out of the box? How many inputs and outputs are available for a turntable, a television, a subwoofer or an outboard DAC? Is there app-based control, equalization and room correction? How does the chassis feel and how good is the front display? And finally, how much measured power does each one actually deliver into real speaker loads?

Price is the last piece of the puzzle. The EverSolo Play CD Edition is positioned as the more premium unit, while the WiiM Amp Ultra undercuts it by roughly $150. That gap is worth keeping in mind, because a few of the differences below are directly tied to it.

EverSolo Play CD Edition: Streaming, Inputs, and Build Quality

The EverSolo Play CD Edition works as a complete streaming front end with built-in support for Tidal, Qobuz, Amazon Music and an Apple Music app, along with AirPlay. AirPlay support is a meaningful differentiator here, because the WiiM line does not include it, and that omission is one of the more common frustrations for people shopping in this category.

The back panel covers a wide spread of connections: a trigger input, HDMI ARC, optical and coaxial inputs, an RCA line input, a phono input with a built-in phono preamp, a subwoofer output, and both USB audio and coaxial audio outputs. A phono stage is rare on an all-in-one unit of this size, and having one means a turntable can be connected without buying a separate preamp.

Control runs through an app that also includes equalization, so tonal adjustments can be made from the listening seat rather than at the unit itself. The front display is another standout: it can show album art, and it offers a range of screen-saver style options, including several VU meter designs.

Build quality is where the EverSolo separates itself most clearly. It is noticeably larger and heftier than the WiiM, and the screen in particular looks higher in quality and is larger than the smaller panel on the WiiM.

EverSolo Play CD Edition: Power, Room Correction, and Measured Output

Rated output is 60 watts into 8 ohms and 110 watts into 4 ohms. Measured results came in above spec at about 69 watts into 8 ohms and about 137 watts into 4 ohms, so the unit delivers slightly more than its published figures suggest.

Room correction is included, and in direct use its results were preferred over the WiiM’s room correction. Combined with the app’s equalization, that gives a useful amount of control over how the system behaves in a real room rather than an idealized one.

One technical point is worth knowing before buying. Output impedance stays low at the bottom end but rises above roughly 2 kHz and climbs steeply by 10 kHz, which makes the frequency response mildly dependent on the speaker load. Measured swings landed in the range of a few tenths of a decibel, up to around half a decibel in places, and with 4-ohm loads the response begins rolling off above roughly 3 kHz. In level-matched listening and blind ABX comparisons, the difference was not reliably identifiable, and with music it would be very hard to hear. Even so, it is a fair criticism at this price, particularly with a less expensive competitor sitting next to it that holds a flat response regardless of load.

WiiM Amp Ultra: More Power, Simpler Feature Set

The WiiM Amp Ultra is rated at 100 watts into 8 ohms and 200 watts into 4 ohms, which works out to roughly 3 dB more output than the EverSolo. In a level-matched comparison, that extra headroom is the first thing that shows up, and it is the main reason to choose the WiiM if the system needs to fill a larger room.

The trade-offs are in features and finish. There is no phono stage and no AirPlay, and the build quality sits a level below the EverSolo’s. On the other hand, its frequency response does not vary with speaker load, which is a genuine engineering advantage.

Remote, Screen, and Everyday Usability

The EverSolo Play CD Edition does not include a remote in the box. Control is handled through the phone app or the touchscreen on the front of the unit, and a separate remote can be purchased if that matters to you. During setup, and when switching inputs such as HDMI ARC, the missing handset is a small but real annoyance, and a bundled remote would be a welcome addition at this price.

The screen is one of the unit’s strongest everyday features. It is larger and higher in quality than the WiiM’s display, and the album art and VU meter options make the front panel genuinely useful rather than purely decorative.

Which One Should You Buy?

Choose the EverSolo Play CD Edition if build quality, the front display, a built-in CD player, a phono stage and AirPlay matter more than raw output. Its measured power slightly exceeds its rating, and it suits a living room, bedroom, kitchen or desktop system where the speakers are reasonably efficient.

Choose the WiiM Amp Ultra if the priority is power per dollar. At around $550 it costs roughly $150 less, offers about 3 dB more output, and keeps a stable response across speaker loads. The lower build quality and the missing phono stage and AirPlay are the price of that trade.

Neither unit is intended for very high power requirements. Listeners chasing serious output will need to look beyond compact all-in-one streamers and toward dedicated stereo or monoblock amplifiers.

Conclusion

These two units are aimed at slightly different buyers, and both make sense on their own terms. The EverSolo Play CD Edition is the more complete and better-built package: CD playback, a phono stage, AirPlay, room correction, in-app equalization and a large, attractive display, with measured power that beats its specification. The main reservations are the missing remote and a frequency response that shifts mildly with speaker load.

The WiiM Amp Ultra answers with more power and a lower price, and it stays stable under different loads. If your speakers are harder to drive or your room is large, that extra output is the deciding factor. If you want one well-finished box that handles discs, vinyl and streaming in a smaller space, the EverSolo is the more satisfying piece of equipment.
