WiiM Amp Pro Streaming Stereo Amplifier Review

[Schlippwhip68]

Tempted but longevity is a concern. Its space on the furniture is minimal and that’s an attraction for me. Sound quality will be probably good but just not sure it would be better than my Denon PMA900HNE (if anyone knows, let me know) but it is the durability of this product that it keeping my finger off the trigger, simply put I just do not have any confidence in the way a lot of amps designed around the TI chip and how they seem to last for.
Heat is a thing with these or more precisely the TI chip and there is no venting on this amp either which until a couple of years ago was a source of much frustration for many with amps using the same chip shutting down due to poor heat management.

I expect at least 10 years out of my Denon amp but this one realistically…I can’t see last more than 3-5 years at best, I would like to be wrong though.
What do you reckon, do I have legitimate reason for concern here? Has anyone been using the regular WiiM amp for over 2 years on a regular basis and noticed anything like maybe a drop in sound quality or performance in some way?

Are you concerned for the longevity of a €350 amp?

 

[somebodyelse]

It looks like they've put some work into thermal management from teardowns like

Don't need venting if you're using a large heatsink, which based on the previously posted teardown appears to be the case. I don't see any reason to be worried about thermal issues with the Wiim Amp. Only open question in my mind is the quality/specs of the capacitors used, which I couldn't see from the teardown unfortunately.

I wouldn't expect any difference in quality between the Denon and the Wiim, realistically.

I use my amp for tv sound, after 3hrs of loud performance it’s just warm.

Why should any one throw away 350? And why should society be okay with all the mining, manufacturing and transport impact if the end product hasto be thrown away shortly,

Received it yesterday.
So far I'm impressed by app and overall functionality of this amp.
Alo positively surprised of built quality and finish if this device. It feels very nice and dense.
Should serve well in our living room. Now it's time to add a subwoofer

ps. @WiiM Team as I see you are about to introduce a subwoofer, can we expect more info about power, size connectivity etc. ?

Hi! The WiiM Sub Pro has an 8-inch driver and Class-D amplifier with 250W max, boasting a frequency range of 25Hz–200Hz. It's got a wired subwoofer input and will also wirelessly pair with any WiiM device. You can read all about it here.

impossible to says ...but 10 /20 year its no for sure but the price is X3 or X2 less and in 5 year you will have 5 gen more news wiim

lcd / oled screen have lifespan , when you look eversolo eemc memory inside ....

thermal is important for condenser , the chip its not problem

Got the Wiimi Amp Pro using the Amazon Prime Day discount for a price of $303 USD! This is the perfect minimalist solution for a secondary set of bookshelf speakers. My source is Roon streaming and the unit integrates nicely with Home Assistant for remote controlled function. My other option is a Douk A5 mini Amp fed via a Raspberry Pi 5 USB to a Topping D10s external DAC. But those are three (albeit small) boxes with two power cords. The Wiim Amp Pro wins on form and function.

in 2 days you come to this conclusion and compare

i receive mine today

i was a little afraid of the power delivered after i see some video on youtube and KEF Q350 are hungry power

before i have pioneer 933 only in 2 chanel mode and the volume must be to 70 to 80 % to be okay with my Q 350

with wiim amp pro 2 light on 6 not 3 i have more power ......

a question some wiim amp we can have core temperature ..there is the option with wiim amp pro ?

 

[SKNG]

Late to the party, voted great,been using it for the past 8~ months after reading Amir review work great on my daily usage,have since replaced it with a WiiM Ultra reason stated on the Ultra thread.

 

[sbronf]

Hi, As a streamer and DAC, how does it compare to the Wii U Ultra? Thanks

The Amp Pro has the exact same streamer and DAC as the Ultra. It just adds an Amp into the chassis.

 

[sbronf]

Ok thank you...do you think that ultra + hypex 122 can be better than the only wiim amp pro? Speakers are diy by myself with scanspeak 6600 and 4" seas midwoofer w12cy003...

Hi, I don't stream only used them for TV ARC audio n USB HDD music playback.
Subjectively they sounds identical when playing at my normal listening level only when push hard the Amp pro seems a bit lacking in power while the Ultra+external amp can keep on going,done WiiM RC for both,for TV ARC audio no difference.
If u listen loud in bigger space WiiM Ultra + a external amp make sense or can go for the Amp Ultra for a 1 box solution,if not then the Amp pro will do the job.

Ok, i'll use wiim amp pro in desktop enviroment, from less than 1 meter from speaker!

Hi, I found this post from a user about the differences between the Wii U Amp Pro and the Wii U Amp Ultra. Can someone explain what this means in the point 2, regsrding inverse polarity? Usually, if you reverse the polarity, the sound sucks; it seems to come from the individual speakers and not the center. That would be a huge bug...maybe the user means something else, but I don't understand. Thanks

These are the measurable differences between the two that I've found so far:

1. Amp Ultra has approx. 2,4dB higher output voltage compared to Amp Pro when set to the same output volume and using the same input signal level.
   • This difference in output level will be clearly audible, but might appear 'different' rather than clearly 'louder' to some listeners.
   • This means that direct listening comparisons of the two amps will likely be tainted by the loudness difference.
   • This difference can be equalized in several ways, but probably the easiest that is reasonably precise is to feed both amps with the same 100Hz sine wave, and measure the output at the binding posts with a true RMS multimeter. Adjust the output volume on either amp until the measured output voltage is identical on both amps.
2. Amp Ultra preserves absolute signal polarity while Amp Pro inverts it on the loudspeaker output binding posts.
   • Interestingly the polarity is not inverted on the Amp Pro subwoofer output. I've opened a support ticket regarding all this and got the answer that loudspeaker output polarity will be corrected in one of the future Amp Pro firmware updates.
   • Until the firmware update is released, the polarity inversion issue of the Amp Pro can of course be worked-around by switching the loudspeaker cable polarity at the binding posts.
3. Amp Ultra is a tiny bit less load-sensitive above 10kHz compared to Amp Pro.
   • With my Revel M16 loudspeakers there's 0,2dB maximum difference between them at 20kHz, and no difference at all below 10kHz.
4. Amp Ultra's power supply has a ground connection, while Amp Pro's does not.
   • This means that one might pick up ground loops and 50/60 cycle hum where the other doesn't.
