Nice!

I'm thrilled to say I was able to find a way to now have a fantastic selection of internet-available recorded music come out of my 30 year old classic Yamaha RX-900 stereo receiver and Klipsch KG4 speakers.

The Yamaha receiver is wonderful but there were no iPhones or Bluetooth wireless devices in those days. But a few weeks ago, I wondered if such a device may now be available to plug into one of its inputs and then be able to hear music from current online sources.

The blafili B4 (no capital by their own imagination) popped up on my iPad with the first search I tried. It appeared to be 100% exactly what I was hoping for. This beautiful small device was precisely the one I would've designed myself, with multiple outputs and a solid, strong signal. It's perfectly designed and manufactured.

The shock is that I had no idea there would be a market for this thing. Could there be enough of us who wanted it? Who else has exactly the right device that came up in my own imagination? I only looked at this one because I couldn't imagine anything any better or more affordable.

I can’t thank Michael at blafili enough to be as responsive, cooperative, communicative, and supportive of the right thing for me. I can now stream from my wireless receiving devices to my speakers, exactly what I wanted.

Couldn’t be any better.

BLAFILI B3 Bluetooth Music Receiver: A Stunning Digital-Analog Synergy

As an audiophile who’s invested in the richness of vacuum tube amplification, I’ve always been cautious when it comes to integrating digital components into my setup. I rely on the Yaqin MC-13S tube amplifier for its organic, full-bodied sound, and introducing a Bluetooth receiver felt risky - until I tried the BLAFILI B3.

To put it plainly, the B3 has transformed my listening experience.

I did experience some initial Bluetooth connectivity issues, but Michael from BLAFILI was prompt, knowledgeable, and intentional in helping me troubleshoot. His support was effective, and the issue was quickly resolved. During that time, I genuinely struggled with the thought of not having the B3 in my system. I had already grown attached to the sound it produced - clear, dynamic, full of detail, and strikingly musical. I didn’t want to go back to the way things sounded before.

Even using basic RCA outputs - not the balanced XLRs the unit offers - I’ve been astounded by the clarity, tonal integrity, and emotional impact of the signal. Streaming high-resolution tracks over Bluetooth 5.1 with aptX HD, the sound retains both depth and nuance. The pairing of the B3’s clean digital transmission with the analog warmth of the Yaqin MC-13S creates something special: a listening experience that is articulate, immersive, and deeply satisfying.

What strikes me most is the preservation of musical dynamics and spatial detail. Vocal performances are intimate and textured. Stringed instruments sing with body and resonance. Cymbals decay naturally into the air, and bass lines remain tight, never bloated. There’s a three-dimensionality that many wireless devices fail to preserve, but the B3 renders it beautifully, even through standard RCA.

And this is where my imagination kicks in: if the RCA output is this good, what might the XLR outputs unlock? I envision an even wider soundstage, a lower noise floor, and a heightened sense of presence. The fact that the B3 offers balanced outputs at all is a clear nod to its professional-grade ambitions.

From a technical standpoint, connectivity is now rock solid. With the antenna exposed and the unit positioned just a couple of feet from my streaming source, I’ve experienced no dropouts, no lag, and no instability. Setup was effortless - power on, pair, and play. I haven’t had to think about it since.

As someone who values musicality over convenience, I never expected to say this, but: I dread going back to life before the BLAFILI B3. It has elevated my system in ways I didn’t think possible for a Bluetooth device. I now listen more often, for longer, and with greater attentiveness. It has made my carefully curated analog setup more flexible, without asking me to sacrifice fidelity.

Final Thoughts:

The BLAFILI B3 is a rare find: a Bluetooth receiver that meets audiophile standards. When paired with something as revealing and tonally rich as the Yaqin MC-13S, it becomes a conduit for true musical connection. If you’re looking to bring wireless convenience into a high-fidelity, analog-forward system, this is the receiver to get.

And if you run into issues, know that Michael from BLAFILI provides excellent support - precise, attentive, responsive, and committed to resolving any problems.

Even with RCA cables, the BLAFILI B3 music receiver is exceptional. With XLR, it could be sublime.

Highly recommended.

Before you ask.

Is a Bluetooth receiver with DAC worth it?

Yes when your source streams hi-res codecs: the B3 decodes LDAC/aptX HD through an ESS ES9018K2M DAC (32-bit/384 kHz) instead of leaving the last conversion to your amp, so nothing is lost between phone and speaker.

Which Bluetooth receiver has both XLR and RCA out?

The blafili B3 outputs balanced XLR, RCA, optical and coaxial from one box — and it is an LDAC receiver on top.

Does the B3 remember settings?

Yes — codec, volume and pairing data are stored on the unit; it reconnects to the last device automatically and the OLED confirms the live codec and sample rate.

Can't get anything to pair with blafili B3 ?

blafili B3 is a Bluetooth receiver not a Bluetooth transmitter, so it can't pair and connect with Bluetooth headset, Bluetooth speaker, Bluetooth receiver and other Bluetooth receiver devices.

Difficult to sync blafili B3 with TV ?

You will need to turn off Bluetooth on other devices first, as blafili B3 can be connected by ONLY one device at the same time.

Do you have to push a button to pair device ?

No, Multi Function Button owns these functions ONLY: ON/OFF; BT Connection Reset; Factory Reset.

Will a Alto Professional Bluetooth Ultimate connect to blafili B3 ?

No, both Alto Bluetooth Ultimate and blafili B3 are BT receivers. What you need is a BT transmitter to pair/connect with Alto Bluetooth Ultimate. Hope it helps.

Will macOS Sonoma use AAC codec with blafili B3 Bluetooth receiver ? I've tried other devices that support AAC but macOS connects using SBC.

Yes, blafili B3 supports codecs of LDAC, aptX HD, aptX LL, aptX, AAC and SBC. blafili B3 connects with macOS Sonoma by AAC codec.

Do you need a Bluetooth antenna for blafili B3 ?

In some cases, you could get signal without the antenna but you must use it to get the best signal.

Can I use multiple outputs at the same time on the blafili B3?

It’s convenient that all outputs( XLR, RCA, COAXIAL, OPTICAL ) are active at the same time.

Digital optical / TOSLINK output red light does not work ?

No, the red light only comes on when there is music playing.

Can't get Bluetooth to work with two devices. One works but I can't get the second device to play.

How to connect blafili B3 with two phones: 1. Power on blafili B3 Bluetooth receiver 2. Enable Bluetooth on the 1st phone, search and connect to “blafili B3” 3. After pairing successfully, disable Bluetooth on the 1st phone. blafili B3 will enter pairing mode again. 4. Connect blafili B3 to the 2nd phone by the same way. 5. After pairing successfully, enable Bluetooth on the 1st phone, click to connect “blafili B3” again. 6. Now both 2 phones are connected to blafili B3. Note: Only 1 phone can play at a time, you have to pause the other.

What if my BT source doesn't support aptX? Can I still use blafili B3 and if so, how will it sound ?

You can absolutely still use the blafili B3, and it will sound great. LDAC, aptX HD are high quality Bluetooth audio codecs that work really well. With that said, in addition to mandatory support for SBC, Bluetooth also includes optional support for many other codecs, like MPEG-1, MPEG-2, MPEG-4, and AAC, all of which have their own advantages, and some of which sound very close to aptX HD and LDAC.
