Genuine audiophile DAC in a powerful Bluetooth receiver/transmitter.
I’ve been working at home during the pandemic and got tired of always having earphones in so I dug an old Panasonic compact stereo out of the basement to set up on my desk. Well, the audiophile bug I’ve had off-and-on for 40 years bit again and the kit speakers soon proved unsatisfactory, so I started upgrading my system. The most important component in any audio system is the speakers, and I picked up a used, vintage pair of Monitor Audio MA 301s, which I think are probably the finest small bookshelf speaker under $1000 ever made. I was using a little Mpow BT receiver to play Spotify through my iPhone, but figured I could get much better sound quality with something that was bigger and more substantial than a device that was smaller than a pack of gum.I tend to over-research everything electronics before I commit, and was very impressed by several reviews I’ve seen of another Bluetooth DAC (digital-to-analog converter - it’s what turns digital signals into analog audio that can be played through an amplifier to speakers or headphones, and most people into high-quality music will have either a standalone DAC or a high quality one in their CD player or amp/preamp) sold here on Amazon for only 25 bucks. It’s made by a company called Mypin and got rave reviews from several audio review channels on YouTube that stated in addition to Bluetooth, it would also improve the audio quality if connected to a CD player, compared to the player’s built in DAC. So I bought the little Mypin, but also spotted this 1Mii unit that boasted an “audiophile DAC” plus also receives better-than-CD Apt-X HD signals and pretty much all other high-quality Bluetooth audio signal types. And so I figured I would give this one a try too, as I could always send it back if it wasn’t notably better than the $25 Mypin.Since we are wedded to a family Spotify plan, and Spotify won’t have lossless, cd quality audio available until some later point in 2021, I also started thinking I wanted to be able to play a lot of my old CDs to be able to have better sound quality than through the Bluetooth and decided to pick up an used Sony five disc carousel CD/DVD/SACD player to use as a transport and run its digital signal into the Bluetooth DAC unit to let the DAC convert the signal to analog (also, my amplifier has only a single pair of RCA auxiliary inputs, so I would be able to use the BT DAC as an audio switch between the Bluetooth receiver and the DAC unit processing sound from my CDs). So I needed a DAC that had a traditional digital audio input, either a coaxial one or an optical one. There are a number of audiophile Bluetooth DAC receivers on Amazon in the $100-$180 range (iFi Zen Blue, Bluedento, Audioengine B1), that have the highly regarded Burr Brown DAC chip in them but surprisingly their coaxial and optical digital connections are for output only to another DAC which makes little sense - Why equip a device with a high-quality DAC that works only for Bluetooth rather than any other digital connections? The Mypin has both coaxial and optical inputs, but the 1Mii has only one optical input; it does have a digital optical output, too, I guess if you have a higher and stand alone DAC and just want to use this unit for the Bluetooth.So my Amazon package with the two Bluetooth DAC’s arrives and I try out the cheaper one first. The Mypin did have better sound than my Mpow portable BT receiver playing Spotify and had slightly better sound than connecting the CD player directly.Then I tried the 1Mii B03Pro+..First thing to note is that unlike any of the more audiophile specific BT DAC’s or even the cheap $25 Mypin one, this unit does not have standard RCA outputs to run a pair of RCA interconnects into one’s amplifier or receiver. Instead there is only a standard 3.5 mm headphone-size output jack. Luckily, I had a 3.5 mm to RCA cable, plus there is one included in the box, but the included cable is very thin, very cheap, and has sound quality commensurate with its appearance. I replace the included one with the relatively inexpensive cable I have used to plug old cell phones into my AV receivers for several years and noted an immediate and very appreciable increase in sound quality, but with some buzzing and feedback in Bluetooth mode, unless the cable was adjusted just right in the back of the 1Mii unit.The B03Pro+ (the “Pro+” means that it has the audiofile DAC) features an ESS Sabre DAC, which I recall vaguely hearing of before, but I did some further research. I noted some audio industry news stating this DAC was being used in an LG cell phone, which initially did not have me very impressed, until I learned that model LG is generally recognized as having the finest sound quality of any cell phone. A bit further research revealed highly-regarded entry-to-mid level audiophile brands Arcam, Audioquest, Cambridge Audio and NAD use the same DAC chip in some of their standalone DAC units, as well as in amplifiers and cd players.So how does it sound? So good that I put the $25 unit back in the box and haven’t given any thought of using that but may give it to someone else. I have found a good test of a system’s sound quality is how it reproduces Mighty Sam McLain’s vocals – – a cheaper system leaves his voice a bit thin whereas a higher quality one renders his voice deep, rich, and perhaps the finest male vocalist in the blues genre. The B03Pro+ does full and proper justice to McLain’s voice.I think the area where this DAC also makes the biggest impact is with soundstage and imaging. With the signal coming straight from the CD player, sound for most recordings is mostly coming identifiably from each speaker and its range is only between the two speakers. When I connected this DAC between the CD transport and the amplifier, the speakers simply disappeared. The soundstage in some recordings expanded far outside of the speakers and certain instruments or singers were precisely positioned at a location between the speakers, sometimes much higher than the level of the speaker. Using Dire Straits’ Private Investigations, one can precisely hear and visualize just where the eerie cat is crying, where the wine glass breaks, and follow the footsteps as they walk across the entire soundstage.The Bluetooth audio is also quite good, but my source is limited, not just by Spotify’s sub-CD quality, for the present, but by my iPhone 7’s Bluetooth- I didn’t realize it at the time, but Apple doesn’t use the highest quality BT transmission- Apt-X HD, which is available for some Android phone users. I haven’t used the unit as a transmitter, for instance, plugged into a television so that one could use Bluetooth headphones to listen. However, as a receiver, it has scary long range. If I want to watch some thing on my phone when I go to bed and I have forgotten to shut the 1Mii off at night, it will play the audio through the Bluetooth DAC instead of my phone, even from across the house. And this is one of its biggest negatives: although it paired very easily with my iPhone and automatically repairs with it when switched to Bluetooth mode, it does not want to disconnect. I either have to forget the device altogether on my phone or go downstairs and shut off the unit, otherwise it will reconnect to my phone, which is mildly annoying.I got a bit annoyed with the buzzing sound that sometimes happens when the cable isn’t precisely adjusted in the 3.5 mm jack in Bluetooth mode, so I bought a better 3.5mm-to-RCA cable, an Audioquest Evergreen. I am only a limited believer in the benefits of audiophile cables and wires, and don’t think that anything above the $50 range typically would produce a notably better sound that could repeatably be detected in a blind listening test by the vast majority of people. However, I did notice a significant improvement in the sound using the Audioquest cable, not merely that the buzzing and feedback had disappeared. On the Cowboy Junkies’ beautifully recorded The Trinity Session CD one can hear subtle breaths by Margo Timmons in her soft but beautiful voice. Her brother Michael’s outstanding (and under-appreciated) guitar work is also improved with more detail. The Audioquest cable is a recommended accessory- the 3.5mm-to-RCA cable that 1Mii includes in the box does not do justice to the audiophile capabilities of this DAC.In conclusion, I am really enjoying high quality music again right on my office desk and this 1Mii Bluetooth DAC is a big part of it. I highly recommend this unit and even if one rarely would use the Bluetooth functionality, it is a very solid value at about 75 bucks just to use as a standalone DAC.

Punches Above it Weight
The Wii B03Pro is a fantastic choice if you're looking for a 5.0 Blutooth receiver to stream music.In this review I'll only be speaking to the audio part in relation to a stereo receiver through the use of iTunes only. I have a recapped 1980 Pioneer SX-3800 stereo receiver connected to a set of KEF iQ1 bookshelf speakers. My Pioneer receiver does not have Blutooth which is expected regarding integrated stereo receivers from the '60's though the very early 2000's.The first thing you should know is that like all Wii products, it's lightweight (plastic) and yet, it does not feel cheap. The B06Pro has a built-in ESS Sabre DAC so you're going to get improved sound quality than cheaper blutooth receivers. The top display is easy to read and not overly present with brightness from the LED's. The display provides very basic info regarding the particular connection and nothing more. It will NOT provide song information. You'll have to spend a little more money to buy the B03Pro+ to get a active sophisticated screen display.This unit comes with a 3.5mm to RCA cable, USB Cable, a Toslink cable, and a 5 volt power supply. The setup is straight forward and you'll be up and running in a matter of minutes. You also have the option of using an external DAC if you prefer.Regarding the 3.5mm to RCA cable connection, there is a misconception, in some circles, that such a connection has inferior sound. That's not true at all. That opinion is nothing more than a misinformed audiophile bias toward traditional RCA to RCA connections.If you don't like the included 3.5mm to RCA and/or Toslink cable then you can buy a higher quality cable on Amazon to easily mitigate the issue and you'll be on your way.I have an iPad from 2021 and an iPhone 12 of which to stream from as well as my MacBook Pro all of which connect very well with iTunes. If you have an Android phone or Microsoft tablet/ laptop / or desk top PC with blutooth, you'll also be good to go as the B06Pro has all of the usual codec compatibilities.It's small and I do like that it has an on/off power button and an on-board volume control which is surprisingly not options for the iFi Zen Blue 5.0 receiver that costs roughly $120 more.The big thing to consider is the price point of $79.99It's considerably cheaper than the above-mentioned iFi Zen Blue, Audioengine, Lavaudio, and Blu Dento 5.0 or 5.1 bluetooth receivers.The audio quality from iTunes has been excellent when used with this device. Instruments are separated and quite detailed. I have not heard any noise or experienced any interference with the signal during playback. Overall everything sounds clean, articulate and full.Keep in mind that your listening experiences may vary. We all listen differently and own different audio equipment in different sized rooms, so reviews regarding sound quality are always quite subjective.I highly recommend getting the added product protection. For roughly $8.00 at the time of this review you get 2 or 3 years of protection in case something goes wrong. Everything is an investment so by all means, get the protection plan for peace of mind.If you're on a tighter budget, in need of adding blutooth to your stereo setup, and still want to get some higher quality sound, then the Wii B06Pro should be on your short list of considerations.Thanks for reading!

👍 👍 👍
They work at about 10 m. The main thing is not to place it near the transmitter and receiver closer than 30 cm.
