WiiM Amp Ultra: Performance Meets Precision

​

We’re thrilled to introduce our most refined streaming amplifier yet, the WiiM Amp Ultra, a high-performance powerhouse built for discerning listeners. Encased in a sleek unibody aluminum chassis with a vibrant 3.5” glass touchscreen, it delivers 100W per channel at 8Ω or 200W at 4Ω, driving up to four passive speakers with stunning clarity and dynamics.

Built with audiophile-grade components, including the ESS ES9039Q2M SABRE DAC, dual TI TPA3255 amp chips, and six TI OPA1612 op-amps, Amp Ultra ensures ultra-low distortion and rich, detailed sound. Post Filter Feedback (PFFB) technology further enhances load-independent performance across all speaker types, delivering cleaner sound and improved amplifier control, especially for complex loads.

To save me from having to cross-check the specs, is this an Ultra with a built-in Vibelink amplification stage, or a WiiM Amp with the front end upgraded to Ultra standard?

 

[MegaUltra]

While I prefer other options AirPlay support is essential in our home. Sad that the no AirPlay trend continues with all the new devices announced today…

+1 airplay is essential, I can’t buy any of these new offerings without it.

 

[Ivan]

I think the real problem is that, with today's Chinese manufacturing and all this class D stuff, making amplifiers and network streaming doesn't really cost them anything.
For example, a digital terrestrial decoder, with dual TV tuner and the ability to record to USB, with HD and HDR output is sold to the public for 48.00 euros. Doing it will cost them 3 euros...

The same goes for all these class D boxes, producing them costs nothing.

While perhaps a decent CD mechanism remains a product that costs them something to produce, so it's not worth it.

 

[hoohoohoo]

PBTL (or dual TPA3255 chips) means that the output impedance is cut in half and the output current is doubled (before the output filter, the influence of which is partly mitigated by PFFB). This means the ability to drive low loads (down to 2 Ω) with high phase angle between voltage and current (complex load) is vastly improved.

OK...so it's still a single load but allows for better driving of the load. Makes sense! Thanks for clueing me in.

 

[Smartplug]

The 6E WiFi (6 ghz) connection that was advertised on this and ultra, when are these going to be active? It was not available out of the box.

 

[canard]

volume and potentiometer handling is a small subject...

(The question was asked by harkpasbt..."" a vibelink regarding amplification and management of it"""... but with one or two chips..?)

if it is a Wiim amp pro... without safety bridling on the amplification side?

 

[Burnside]

Say hello to the WiiM AMP Ultra, Sound & Sub Pro | Darko.Audio

More Munich tease: a streaming amplifier, a streaming speaker and a streaming subwoofer.

darko.audio

Edit: with the now almost obligatory mistake - there’s no suggestion that it won’t support AlexaCast so you won’t need to rely on the WiiM app to play Amazon Music.

It's neither nor, I tend to think.

Exactly. Parallel bridging doesn't increase power output into 8 Ω or 4 Ω, but ensures there is enough current on tap to feed more demanding loads.

if it is a Wiim amp pro... without safety bridling on the amplification side?

Measurements confirm that the Vibelink Amp has better PFFB implementation than the Amp Pro, so I'd hope for the former. If this unit brings dual chips, that's another step forward for those with hard to drive speakers.

of all that there remains...
the necessary improvement because one of the functions offered by wiim, making the difference, rc modes, rc / sub etc... and that is the hard subject...

The vibelink has the ESS 9039Q2M DAC.
a single TI TPA3255 amp chip,
and the six TI OPA1612 op-amps.
The pro has the ESS 9038Q2M (same as the ultra), but the same amp chip, though limited at 60w instead of 100w. (according to the spec sheet on the site)

So, currently, this seems to have the two chips as an advantage when it comes to the specs.
Other than that it seems to be a vibelink and ultra in one box.

 

[reniro]

is the ES9039Q2M better than the ES9038Q2M from the Wiim Ultra ? "The internet" says the 39Q2M would be better for stereo ?

 

[Ivan]

assuming it costs much less than the sum of the two separate components, it seems to me that Wiim have practically killed all their before products: Ultra, Amp, Vibelink etc... making them useless compared to this.
It seems to me a kind of commercial suicide (even more so considering that the Vibe link has been on sale for a few weeks and the ultra is almost just born...).

Time will tell if this is another brilliant business analysis ... or ... not.

On the contrary imho - the ability to add the vibelink to currently owned devices means you don’t have to throw away your investment. For new buyers, the amp pro is just another step in the progression from a WiiM amp (entry level), amp pro (better) to amp ultra (best). Similar to the streamers: mini/pro, pro plus, ultra. Different entry points depending on your needs/budget. Just because a supplier comes out with a newer, more expensive model doesn’t negate the existence of less able, less costly models in their range.

@RyanWithWiiM

Thanks for headsup for the upcoming WiiM Amp Ultra. It has so many features and functions. It would be very informative if you can show only differences compared to Ultra + Vibelink Amp combination. This way, one can make fit-for-purpose decision between Amp Ultra and Ultra + Vibelink Amp. As far as I can tell, the only differences between two configurations, are;

• Smaller footprint for Amp Ultra
• Dual power amplifier chips for Amp Ultra
• 1 volume knob for Amp Ultra - two volume knobs can be confusing for some users

Am I missing anything? Speaking of missing AirPlay, I am willing to pay ~$100 premium which is equivalent to adding WiiM mini as AirPlay receiver via toslink.

 

[Ivan]

It is obvious that anyone who has already (unfortunately) bought an ULTRA will buy the Vibelink, but any new buyer will orient themselves towards this all in one.
It seems to me that they have made war at home, considering, I repeat, that they had just launched the Vibe link.

The vibelink is an amp without the streaming functions. You'd buy it to pair with the ultra, or any other streamer from any other brand, or if you didn't need streaming functionality. (for example just hooking it up to a cd player)

You'd buy the ultra (or one of the other streamers) if you needed streaming.

This is an integrated amp / streamer. You don't buy this if you need any of the other two options.

Yeah, as I alluded to earlier WiiM now have a stepped streamer range, a stepped amp range which the amp ultra completes, and the vibelink which allows you to transition from the former to the latter. With the wireless speakers and the sub, WiiM are slowly completing the picture. Looks like there’s a strategy at play

 

[canard]

seems to have the features of the amp pro due to its inputs/outputs...
an ultra " screen"...

remains to observe the quality of the amplification, see the volume processing, (and type of analog input too)...

that's all...

wait an see ;-)

PFFB is completely independent of PBTL or BTL.

PBTL (or dual TPA3255 chips) means that the output impedance is cut in half and the output current is doubled (before the output filter, the influence of which is partly mitigated by PFFB). This means the ability to drive low loads (down to 2 Ω) with high phase angle between voltage and current (complex load) is vastly improved.

I just hope that the "dual chip" design is real this time. The first announcement of the Vibelink Amp also contained this term, but was later corrected to single chip.

Is dual chip configuration PBTL or dual mono (one per channel)?
