Introducing WiiM Amp Pro

A not yet so widely adopted mathematical model that aims at providing an "equivalent" ohmic impedance, representing a similarly hard to drive load as a complex impedance (high phase angle due to inductive or capacitive load).

EPDR = Equivalent Peak Dissipation Resistance

Heavy Load: How Loudspeakers Torture Amplifiers

Why, in loudspeaker reviews, is impedance measured (assuming that the magazine in question bothers to measure anything)? Generally, for one principal reason only: to establish whether the speaker presents an "easy" or a "difficult" load to its partnering amplifier. In the design context, much...

Heavy Load: How Loudspeakers Torture Amplifiers Page 2

All this was clear from Eric Benjamin's aforementioned AES article, but the message seems not to have filtered through in the 13 years since (footnote 5). Loudspeaker impedance continues to be assessed by considering modulus and phase separately when, as Benjamin showed, there is a much better...

Luckily, the WiiM Amp Pro is very stable into reactive loads (high phase angels) at least down to the real part of the impedance (the ohmic resistance) being no lower than 4 ohms. Unfortunately, Amir doesn't bother to do tests at 3 ohms ohmic resistance and different phase angles. It doesn't have useful output into 2 ohms, which is to be expected.

There's always someone that will complain about something on the internet. Fact. What I don't get about all the Airplay hubbub is that the primary use case for most people with the WiiM devices is online streaming, is it not? Then why would you even need Airplay in the first place? If the user is trying to pass content between more than one system in their home, then the WiiM boxes are inexpensive enough, just buy one for each system, no? If these things were $1K, $2K and up streaming boxes like some brands, then I get it, you'd want full functionality for all desirable and conceivable goodies. But these boxes are in the $100 to $300-ish range, some people are just never satisfied I guess.

Yeah im totally on the same page as you. I think a part of the hifi hobby for some is to find faults in products so they dont have to buy it, i dunno. For me this is a perfect device for its price. My system has never sound this good.
If there was no bluetooth on here i would still buy it, because who uses bluetooth for listening at this price point. Thats not the point of a streamer i feel like.
 
The purchaser of a device might not necessarily be the sole user. So yes, they might only stream hi res from say Qobuz, but others in the household might expect the ease of use that airplay and even Bluetooth can offer. It’s not unreasonable to envisage a situation where a friend might visit and talk about a piece of music and want to open their iPhone, select your hi fi as a target and play it only to find this system you’ve raved about doesn’t support airplay. Hence the “hubbub” from certain members…

Yes it's about the ease of use and the immediacy mainly - especially in those situations. All of us on the forum probably know that it's not lossless or bit perfect. But it seems like the Airplay ship has sailed a while ago :)

Luckily the Airconnect solution seems to work nicely

Such casual listeners with such modest and occasional convenience needs, they can use Bluetooth and be done with it. I literally don't get all the angst and handwringing on this board regarding loss of Airplay on the newest WiiM boxes. These are $90 to $380 boxes, get over it. You want the kitchen sink, including Airplay, buy a streamer device from another vendor. We know who they are. The Bluesounds start at what, $300 for the cheapest and go up from there to over $1000? But you'll have your precious Airplay! :rolleyes:

I know how a device in my home is best used and that includes AirPlay. Your house is different and that’s fine. And I can say that without sounding condescending. Give it a try.

I totally get your point, but it's a little more nuanced than that because the feature is present on the previous cheaper devices. And the communication was a bit awkward to say the least - with them first saying it would come to the Ultra at a later stage.

How can casual listeners as you put it, use Bluetooth to send audio to multiple speakers throughout the home? :rolleyes:

You're trying to invent rare use cases to justify your frustration with Apple's licensing power over a small company like WiiM, OK :unsure: If you have family members and visitors to your home casually wanting to send audio to speakers throughout your home, OK for you I guess. That is not a use case that most people deal with.

Then buy a different product. Or will you be like others on this board and complain about the loss of Airplay for the next six months.

No, I'm Not, and I'm Not frustrated, I regularly send music to multiple AirPlay compatible speakers, and WiiM products throughout the house.

You, sure, you're the system owner. But I thought we were talking about casual users like family members and visitors to your home. That's the use case the OP was describing. My argument is that this is not a common situation. Friends don't come to my home and say "hey, here's this cool song I came across, let me play it for you on all of the speakers in your house, including your expensive audiophile stereo system!" That is not realistic. The inability of the newest WiiM boxes to accommodate that scenario via Airplay is not a significant demerit for the devices. IMO of course.

Having a phono input on an amp would make more sense than on the Ultra.

I also think... will do a little "all in one" "complete for now ( no cd no tuner fm)"... (with one num input and one analogique...ok)
but “it’s done, it’s done”
