Such an "end game" ( which never really is an end) would cost significant more than WiiMs business idea for a cheap streamer. And if one is prepared to pay let's say more than 1500 €/£/$ he does not have to wait for WiiM. Such stuff is available already.
Excellent point. There are already products out there that do what a lot of people request here. A lot of requests are made by those that are excited about what we already have and suggest improvements. In my case firmware increased the value of the Pros to me and I just bought 2 more. I don't think it was WiiMs intention to obsolete the Mini (as far as Squeezelite firmware), but lower price and therefore lesser hardware did not allow the upgrade (as of now).
Because of the price, $99 and $150, I made the decision to convert 6 existing audio stations to streaming. If the price for a decent device was $500 or more, I probably would not have been able to add streaming to all six stereos. And it would hurt a lot more to have to replace an expensive unit or 2 for an extra feature.
The price point and quality of the WiiM is just right. A lot of us are getting use to a device that has hardly any controls and is accessed by a phone or tablet. I think the WiiM Amp is a good idea for casual users, so a unit with an amp and volume control seems like a good idea, but even that product will be accessed with a phone or tablet for content selection, so the volume could be adjusted by the app or WiiM Remote.
My point is that there is not much of a need to access the physical WiiM and I am rethinking that a premium box is necessary? Other then no USB digital out, I think the current Pro is great, but if I was to install it out of site, like behind the amp, I would want it as small as possible.
I am curious if most users want to see their WiiM or would hide it if it was not necessary to touch it? Anyway, whatever new products come out, I think this headless design is WiiMs future and new features will be in the internals and firmware.
After you setup your system, it all comes down to the user experience, and that is the sound quality and how you enjoy using the app. The WiiM Home App works very well, but could use a few tweaks like an alphabet indexer when scrolling a long list of artists or albums. It would also be nice to be able to pool Previously Listened to, and Playlists across several phone or tablet devices (user choice). There are a few other ideas, but the app overall works great.
There was a lot of excitement when WiiM announced upcoming Squeezelite support. There are several apps out there that have a better user experience then the WHA but are dependent on using the Logitech Media Server (low cost hardware and free software). This was possible before the Squeezelite firmware, but required 2 buggy "plugins". I questioned if the new firmware would eliminate the need for the 2 plugins. It did eliminate the one plugin so the Logitech apps see the WiiM devices.
If you want to use a LMS type app AND need to use the WHA for some applications, you still need to use the other plugin so that the WiiM can see your LMS music library, but that plugin is buggy and obsolete. I don't know if that plugin is open source, but it would be nice if someone tried to fix it so it displays Album Artist rather then (or in addition to) (song) Artists.
The Pro Plus is also a great idea. A better DAC without much more cost. And audiophiles can sill use an external DAC if they want.
Like I said, I think the current approach with some tweaking will make WiiM hard to beat. Small, headless, and low cost.
