    DTS Play-Fi Has Major Design Flaws

    Most HiFi manufacturers license certain technologies from other companies to enhance their products. These manufacturers either don't have the in-house engineering capability or they'd rather not reinvent the wheel, when it can be purchased for a moderate fee. This has never been more apparent than now, with the rise of computer audio. HiFi manufacturers started licensing Gordon Rankin's Streamlength(™) asynchronous USB code, StreamUnlimited's and ConversDigital's network modules as soon as computer based digital gained a foothold.

     

    One technology that has gained more market share in HiFi lately is DTS Play-Fi. Several manufacturers have licensed Play-Fi as the core of their network audio offerings. The Play-Fi Products page lists a who's who of manufacturers from small to enormous. Play-Fi appears to offer quite a bit to manufacturers and their customers, such as network connectivity, and services such as Spotify, Tidal, Pandora, Amazon Music, SiriusXM, and DLNA. In addition, each manufacturer can offer customers a custom version of the mobile app for iOS and Android. To most end users these apps appear to come directly from the manufacturer rather than something the manufacturer licensed and logo'd. What's not to like?

     

     

    I hate to be the bearer of bad news or the dream crusher, but once in awhile something irks me and feel compelled to write about it. I'm writing this article in an effort to both educate potential consumers and hopefully nudge DTS into making some adjustments. Given the size of its business, I don't think DTS really cares much about CA, but at least we can try.

     

    hi-res-100px.jpgFirst, the good things about DTS Play-Fi. The platform supports many services, both large and small. It also supports interoperability between manufacturers. For example, a single iOS app can stream music to Pioneer, Polk, and Paradigm speakers all at once. This is great for most consumers who like to mix and match components or pick up whatever is on sale at the local BestBuy. If it has a Play-Fi logo, it'll work with one's existing Play-Fi components. Play-Fi also supports lossless audio and high resolution playback. It will play up through 24/96 bit perfect. When streaming higher sample rates it will downsample on the fly. This is actually nice, given that Sonos won't even play music at rates higher than 44.1.

    Now for the items that everyone should consider before purchasing a Play-Fi enabled device.

     

    1. All music, with the exception of Spotify, must stream through the device on which the app is located.

     

    2. DTS lists the DLNA logo on its site and writes that Play-Fi is compatible with DLNA, but the devil is in the details. I can see a politician saying Play-Fi works with DLNA, but DTS should put a very large asterisk next to the DLNA logo on its website.

     

     

     

    Music Through Mobile

     

    DTS requires that all audio sent to a Play-Fi device route through the mobile device controlling playback. For example, when using a Play-Fi iOS application from any manufacturer and streaming music from Tidal, Pandora, Deezer, SiriusXM, etc... all the music must first stream from the Internet to the iOS device, then from the iOS device to the Play-Fi device. The only exceptions are Spotify and the Play-Fi desktop application.

     

    Think about that for a second. It's like we are back in 2008 when Apple's AirPlay was the only option. By the way, Apple's AirPlay works just like Play-Fi. Not only is this subpar for most novice music lovers, it's unacceptable for technically inclined audiophiles.

     

    The one device in a home that requires batteries, doubles as a flashlight, is used to notify the authorities when there's a fire or a prowler, receives frequent interrupting SMS messages and calls, is also the single device that all DTS Play-Fi audio must route through.

     

    Even if the music originates from within one's home network, on a DLNA server, the audio still must route through the mobile device. Imagine if televisions routed all DVD, Blu-ray, and cable TV service through the remote control. Talk about showstopper. This would never happen.

     

    Compare DTS Play-Fi to Google's $30 Chromecast Audio device. Chromecast Audio doesn't route a single song through the mobile device. It communicates directly with the cloud. Start playing music and shut off your phone. Nothing happens to the music. Try that with a Play-Fi device. The party stops along with the phone.

     

    I see this as a problem for all users of the DTS Play-Fi platform. Many times I'm disappointed by technology, but I chalk it up to my own strange edge cases. Play-Fi is different in that it's in millions of consumer devices and all mobile phones suffer from battery life issues, text message interruptions, and phone calls.

     

     

     

    DLNA (Except When It Isn't)

     

    My other big complaint with DTS Play-Fi is it's DLNA support. All over the Play-Fi website and knowledge base, DTS claims DLNA support for all Play-Fi devices. This is borderline fake news. The only way to use DLNA with Play-Fi, is to use a DLNA server, stream the audio through the mobile device running a Play-Fi app, and on to a Play-Fi certified piece of hardware. This is antithetical to how DLNA is supposed to work. Sure, DLNA is the most nonstandard standard and it has issues, but come on DTS. This isn't even close to DLNA support.

     

    True DLNA requires three components. 1) A DLNA server, 2) DLNA control point, and 3) DLNA renderer. Any of these three devices can be from any manufacturer and serve audio to any other DLNA device. At home I have a Synology NAS (DLNA capable) that sends audio directly to a DLNA capable dCS Network Bridge, all controlled by a DLNA capable app on my iPad from Linn. Any of these three components can be replaced by another DLNA device or app from any manufacturer.

     

    If Play-Fi was a true DLNA technology, one could stream from a Synology NAS directly to a Play-Fi certified piece of hardware, while controlling playback from the Linn application. Also, the music wouldn't route through the iPad or other mobile device.

     

    The only way Play-Fi works with DLNA is when using a DLNA capable server such as one from Synology or JRiver or QNAP, and using a Play-Fi iOS or Android app and a Play-Fi certified piece of hardware. Did I mention that the audio must route through the mobile device? Oh yeah, a couple times.

     

    Note: The Play-Fi audio devices appear on one's network as true DLNA devices. Apps such as JRiver can see the Play-Fi devices, but can't send audio to them. This ads even more confusion to the mix and will only serve to frustrate consumers.

     

     

    Wrap-Up

     

    Consumers should educate themselves on DTS Play-Fi before purchasing a Play-Fi capable component. The platform may be a perfect fit for one's lifestyle and needs. Or, it may be a nightmare with hidden problems that are really there by design. Other platforms have been streaming directly from the cloud to a playback device or from a DLNA server to a DLNA renderer for many years. Requiring a battery operated mobile device to be the audio traffic cop, is nothing short of silly, inconvenient, and counterintuitive.

    Just created an account to say thank you for this act of public service. Oh how I wish I had come across this info much earlier, several years ago. I, like most others, got some very cheap Play Fi gear (clearance/thriftstore/used). I had delusions of this stuff working, multi-room and all. What I got instead was so much lost time, headaches, and useless expertise in the disaster of Play Fi software. I can now operate and set-up all this Play Fi stuff like a ninja, well, a hobbled-by-Play-Fi-ninja, just in time to realize it's a lost cause. It almost sort of works, but the manner in which it works is absolutely unacceptable. It is so clunky it frustrates and bewilders with its strange logic and strange function. Another issue with Play Fi speakers is that there is no input/output standardization. In other words, speakers from different brands will have all sorts of different I/O configurations. This is not flexibility; it is another inconsistency headache for the Play Fi end-user. Also, some Play Fi speakers re-broadcast line in to other Play Fi speakers, while other Play Fi speakers do not have this functionality. Because of the inconsistency, it is difficult for Play Fi customers to know what to expect from their Play Fi speakers. This is not good brand functionality. It leaves customers confused. And last I checked, to do "critical listening" mode, it wanted to do it with only one speaker! What is the point of one speaker critical listening mode? Seriously?

     

    The speakers actually sound pretty good 3 Pioneer VAFW40s (were 4 but 1 died), 1 Klipsch RW1, 2DefTech W7s, plus a Phorus PR5 receiver). When played with good sources every speaker put out high quality sound. I got everything working such as groups, multi-room, stereo-pairs, broadcasting line-in to other Play Fi speakers, etc. These Play Fi speakers were never main/primary speakers thank God. The problem is not just the software, but the engineering, which makes any software improvement (whether bugs or features) irrelevant. It is so badly designed that it can barely, or often not at all, do what it promises it can do. That the speakers sound decent is a fact that exists only to tantalize and frustrate, because you will not have the freedom to actually access and experience your music without constraint. The Play Fi app experience sucks compared to the native Tidal application for instance. Although it can, if conditions are met, pass a high resolution signal to the speaker, Play Fi is a soul-less, illogical mess of engineering which subjects its users to experience its foundational design flaw: I never wanted my music to stream through my phone or tablet; of course, I simply wanted to use those as remote controls; and I wanted a short, direct, and sensible signal chain. DTS should abandon Play Fi. They should support existing Play Fi products for five years. In the meantime, Play Fi should start over and try again. It does not seem fair to ask engineers to fix Play Fi. I don't believe it is fixable. I'm guessing that Play Fi is such a mess that it could never be considered for Tidal Connect certification. 

     

    It didn't help that my s/o is a computer engineer who was used to the bluetooth and sonos experiences. Anyhow she said wanted some patio speakers so I quickly volunteered two Pioneer VAFW40's (Play Fi speakers) for the job. I hung them under the eave with some fishing net, each in an adjacent corner. Tested them and they sounded good, even a little bass reinforcement from the corner placement. Then I helped her download the DTS Play Fi app (and also the Pioneer Play Fi app, just in case) and yes, it didn't go well. We set them up as a stereo pair. She could never understand Play Fi because she had basic expectations of what it should do. I would try and explain it to her. She had good questions. She had simple requests, like having her phone audio play on the patio speakers like bluetooth or like sonos does. That was a rough patch, but then her next request: she shows me her phone, and the horror, it was youtube!  What was I and Play Fi supposed to do with that? I wonder what techno-magic she'd experienced to even think to attempt such a thing? I mean in 2023, playing the audio of a video-stream wirelessly to some speakers? Is it possible? Yes, depending on which equipment is used. So I start to explain to her how Play Fi won't do that. Anyway, a few days go by, and she has more good questions and more simple requests. To each of her questions or requests, I had to answer, Play Fi won't do that. She would then explain that sonos, and yes even bluetooth, could fulfill her requests, then she would ask why these Play Fi speakers couldn't do simple things. The entire experience, everything, is controlled by the DTS Play Fi diluted crap version of the Tidal application. She would ask why the Play Fi speakers were better than sonos or even bluetooth when they could do less, and do it less easily? She understood Play Fi was broken (before it began) quicker than I did.

    But there are some benefits of having some DTS Play Fi speakers. They teach you what you want and what you don't want. Good sound, yes. Bad foundational engineering, no. No, not at all. There now exists a product that does everything I want it to do. It's called the Wiim Pro. You might also look at their Wiim Mini. It is a bitperfect audio streamer that gets the signal directly into your audio chain without having it richochet through your phone non-sense. You can pair the Wiim Pro or mini with an inexpensive DAC like the SMSL SU-1, which gives you bit-perfect Tidal (with or w/out MQA, whatever your preference) to feed directly to your DAC. Since the Wiim Pro was well-engineered and can do Tidal Connect, none of the aforementioned headaches of Play Fi will afflict you. Tidal Connect is what Play Fi tried and failed to be. The combination of high resolution music with the easily directable Tidal Connect is the best music streaming experience I've found to date. It is the experience of the the Wiim Pro with Tidal Connect which has taught me that Play Fi is unusable for me. The Wiim Pro can also do your TV audio via its optical input. 

     

    But all is not lost if you still have Play Fi speakers. Things you can do with Play Fi speakers:

    *Initiate the divorce of an otherwise happy couple

    *Some can be used as decent Alexa speakers

    *Throw a bluetooth dongle on it

    *Put a Wiim Mini streamer on it, but that is an expensive solution for a broken speaker, or a Chromecast Audio (if you can find one)

    *Donate them to a thriftstore

    *Give them away to someone you don't like

    *Use as landfill material

    *Though not rated for the outdoors, Play Fi speakers hung under an eave have a lifespan of about 1.5 years

    *Paper weight

    *Target practice

    *Boat Anchor

    I am on the otherside of it now, but hopefully others can avoid this Play Fi pitfall. Again, thank you for this much needed analysis.
