Mass Fidelity Relay Hi-Fi Wireless Bluetooth Receiver Review
Sound quality of Bluetooth wireless music has got more attention than before, recently a HiFi standard Bluetooth receiver by Mass Fidelity has launched with the name "Relay". After reviewing this receiver, I can finally use the words "Bluetooth" and "high-quality audio" in the same sentence.
Streaming music wirelessly from your smartphone to any sound system in True high fidelity is only aim of Mass Fidelity. They dedicated themselves to this the last three years, and they finally brought us this Hi-Fi Wireless Bluetooth Receiver. Relay is excellent in every respect, its hardware is totally different compared with those products under 100 bucks. Home electronics, other wireless devices and fluorescent lights can produce electromagnetic radiations when operation. If that radiations were picked by a wireless receiver without filtering mechanism, the noise like "buzz" is given out as a result. Relay’s Grounding Scheme includes three separate ground domains and a bulk decoupling capacitor to eliminate any possible radiations or ground loops, which may effect the signal transmission. A legendary and costly 24-bit Digital to Analog Converter (DAC) module, Burr-Brown 5102 is built to deliver a solid 2 Volts RMS output power to your analog Hi-Fi system. That module usually can be found in top shelf audiophile speakers and Blu-ray players. A 2.2DB external high gain antenna for extending the transmit range is included, which ensures a reliable and stable link. Relay also has AptX, a superior digital audio codec used in later-generation smart devices (particularly Android OS). The creator of Relay tried everything useful to ensure the device they made is a HiFi device not a generic low quality receiver.
Great HiFi sound
Hardware and designing only entitle the potential of good sound, then an AB testing with Logitech Bluetooth adapter was performed as any good reviewer would agreed. I run the test using my DENON D-F107 micro component system, which is not so good but with 192kHz/24-Bit enough for the comparison. The Relay streams both AAC and Apt-X over Bluetooth. In order to get the best possible quality streaming, apt-X must be supported by both source device and receiver. So I chose apt-X enabled MacBook Pro to do the primary streaming work. The apt-X Bluetooth stream really sounded good, the vocals matched up perfectly as did the bass and guitar, the bass seemed pretty on streaming lossless files. a suspicious "hint" of the top frequency response had be detected when aptX stream, but it was very subtle and I’m not sure when play back. I played more and more tracks, I have to say it sounds really good. When it came to Logitech receiver,stream the sub-band coding of the A2DP Bluetooth stream. it sounds flat and lifeless compared to the better aptX stream, so keep that in mind. Relay won test with a true HiFi sound, which I had not expected when I began the AB testing.
Relay provide the listener an unique connectivity method using two gold-plated switchable RCA connectors. They can operate either as analog or digital outputs. The receiver integrates well with any Hi-Fi audio system. You just connect the stereo analogue outputs on the back to your AV receiver with supplied RCA-RCA signal cable or RCA-mini cable. Anyone who prefers to digital output can do the reversion by pashing and holding the rear-panel control button for about 5 seconds, then switch the analog output into 24 bit S/PDIF digital output mode. Outboard DAC or surround receiver can be connected through either output jack to digital inputs of them. Relay can feed two digital streams at the same time. For example you can feed one digital output to a surround receiver or primary DAC and the other to a headphone amp or etc.
A solid block of aerospace grade aluminum with elaborate manufacturing is milled out for the box, and those really nice rounded corners that makes it look like something Apple style. It matches perfectly at home sitting next to even the costliest and most attractive home audio components. There’s nothing wrong with showing off your cool stuff. Even though it’s small enough to hide away you’ll want to display it proudly out in the open.
Party Pairing TM technology bring the social element to Relay. Every people at the party is allowed to take turns being the DJ by the amazing tech! It’s a global jukebox only limited by the amount of music you and your friends can tap into from both stored music files or streaming services.
The Relay has a combination of advanced hardware and firmware, it preserves all the musical detail, dynamic range and full bandwidth response. This Hi-Fi Bluetooth wireless receiver works great and will stream high quality audio to your existing stereo system, so you can walk around without docking or wiring anything. Enjoy all your digital music on your favorite sound system, whether it’s stored locally or streaming from the cloud. This beautiful and power device is helpful to eliminate the prejudice of bluetooth wireless music, It is not merely a collection of low quality sound any more. The emotion-packed artistic expression can be used to describe the wireless sound quality from now on. Overall, I really like this little aluminum box. If you don’t want for only half of your music’s performance and have a desire for True HiFi sound. This is something you can not afford to miss!
