Despite the small size, which can be placed horizontally or vertically, theWXC-50 packs in a lot of features. It works with DLNA, Airplay, Bluetooth, has an optical input, and a standard aux input. It has digital outputs, a trigger in/out, and a subwoofer out if you want to use it with powered speakers., Its uses capable ESS DACs and the WXC-50 can handle hi resolution files, including DSD (up to 5.6 Mhz) and FLAC files up to 24/192.
The Yamaha MusicCast app give you complete control over the extensive features. You can also tweak sound quality, access your server, access internet radio, access Pandora, etc., with the app.
The device also comes with its own small remote. It can select the different inputs, access favorited internet stations with 6 presets, and pause, play, skip and go back to prior songs. The remote will even allow you to pause an Airplay signal or skip the song even though it is being served music from the iPhone.
All the Wonderful Things
Speaking of Bluetooth transmitting, it does not work with all audio. I could get it to play music on my Denon receiver when I would send it 24/192 files from my server, but it could not handle DSD. It worked with internet radio, but it would not send out an Airplay signal. It also worked with the optical digital input and the analog input. However, there is a lag between the main speakers and the Bluetooth receiver, so I would not recommend this as a whole home solution. I would pick which device you want to listen to music on and mute the other device. I should mention that Yamaha has many MusicCast devices and speakers and I would guess that they would handle the lag better, but I do not own any other MusicCast devices, so I can't comment on how they would work together.
How I Use It
One of my favorite ways to use it with the Marantz is to tell the Alexa to send music to the WCX-50 (which pairs fine with the Echo Dot for receiving Bluetooth audio) and then telling it to turn on the Marantz and play music. I can do all of this from the couch via voice. I have my extensive music library on Amazon's servers, so I can listen to most of my favorite music that way.
For more serious listening, I use the Little Dot MKIII with a pair ofHiFiMan headphones and the sound quality from the WXC-50 is outstanding. Even when using Bluetooth as a source, its EQ capabilities, like advanced Bass Extension and Compressed Music Enhancer, make it sound very good.
In the picture above, you will also notice that I also have a Little Dot DAC1. I haven't removed it from the setup because I bought the amp and DAC together, but the Little Dot DAC1 will also take a USB feed from my iPhone via the Camera Connection Kit (USB3.0 to Lightning cable) and send the digital signal out via analog (using the DAC). To get that benefit, I have the Little Dot DAC1 feeding the analog inputs on the WXC-50, so it all works great together. Honestly, I could live with Airplay rather than a direct connection, but this just gives me a bit more flexibility if I am having home network issues.
