One free scan finds every outdated or missing driver and matches the right update for your exact hardware.Free scan · exact hardware matchFor streaming phone, tablet, or computer audio through an existing stereo, look for a Bluetooth audio receiver—not a transmitter. Choose one with an output your stereo can accept, then check that its supported Bluetooth codecs overlap with those of your source device. The examples below are manufacturer-documented options, not a tested sound-quality ranking.
What makes a Bluetooth adapter right for a home stereo?
A Bluetooth audio receiver takes wireless audio from a phone, tablet, or computer and sends it to a non-Bluetooth stereo through a wired audio output. In receiver mode, the FiiO BTA30 Pro, for example, connects a phone or music player to a non-Bluetooth music system (FiiO BTA30 Pro).

Start with the stereo’s available inputs. A receiver’s RCA output suits a stereo with RCA line inputs; optical/Toslink or coaxial output suits a stereo with the corresponding digital input. The receiver and stereo must share a connection type. If you choose a digital output, check the stereo manual for supported input formats and settings.
- RCA analog: A straightforward match for many amplifiers and stereo receivers with stereo line-level inputs.
- Optical/Toslink: A digital connection, if both devices have the matching port.
- Coaxial digital: Another digital option where both receiver and stereo provide the matching connection.
Check what is included in the box before ordering any cable. The product specifications cited here establish output types, but do not establish package contents for every model or region.

Bluetooth receiver options for different stereo setups
These options differ in documented connections, codec support, and extra modes. Their specifications come from manufacturers; they are not independent listening-test results.

How to choose for sound quality
Match the codec at both ends
Codec support is a source-and-receiver combination, not a receiver-only guarantee. A receiver may list aptX HD or LDAC, for example, but that format is useful only if the sending phone, tablet, or computer supports it too. Check the source device’s specifications or Bluetooth audio settings, and compare them with the receiver’s supported codecs. If there is no shared higher-quality codec, the connection will use a compatible option available to both devices.
Recommended Free Tools
Codec labels and digital output resolutions describe technical capabilities; on their own, they do not prove that one receiver will sound better in a particular room or system. Dayton Audio lists up to 24-bit/48 kHz for the BTR02’s optical or coaxial output, but that format specification is not evidence of an audible advantage.

Do not treat feature lists as a listening ranking
The manufacturer pages document useful differences in outputs, modes, and codecs, but they do not provide a controlled, independent comparison of these models’ sound. There is therefore no evidence-based “best sounding” winner among these examples. To narrow the choice, first eliminate units that cannot connect to your stereo, then compare codecs supported by your source and any extra features you actually need.
Read range claims as stated conditions, not guarantees
Manufacturers publish different Bluetooth range figures and conditions. FiiO states approximately 30 m under normal conditions and notes that operating conditions and modes affect operation; Auris lists 30 meters/100 feet; Pro-Ject states up to 10 meters in direct visibility. These are manufacturer claims, not guaranteed distances through walls or in every home. See the respective FiiO, Auris, and Pro-Ject product pages.

How to connect Bluetooth to an old stereo
- Confirm the stereo input. Find an unused RCA, optical/Toslink, or coaxial input, then select a receiver with the matching output.
- Connect the receiver to the stereo. Attach the appropriate audio cable and connect the receiver to power as its instructions specify.
- Pair the source device. Open Bluetooth settings on the phone, tablet, or computer, put the receiver into pairing mode if required, and select its name. Audioengine’s B1 instructions say to select “Audioengine B1” in the source’s Bluetooth preferences.
- Select the matching stereo input and play audio. Set the stereo to the input used for the receiver, then start playback from the source device.
For its B1, Audioengine documents the sequence of connecting audio cables, connecting power, choosing the receiver in Bluetooth preferences, and playing music in its setup guide. Follow the chosen model’s own instructions for pairing mode, input selection, and any digital-output settings.

Which option fits your needs?
- You only need wireless playback into a stereo: Prioritize a receiver with an output matching your stereo; transmitter and DAC modes are extras, not requirements.
- Your stereo has digital and analog inputs: Compare models by the output you prefer and can configure, rather than assuming digital is automatically better.
- You want a particular codec: Verify that your source device supports it before paying for that feature.
- You want to use the receiver in other ways: A switchable transmitter/receiver or DAC model may offer flexibility, but confirm that its additional modes match your equipment and intended connection.
