FiiO has rebuilt one of its most popular desktop units around a very different heart. The FiiO R7 R2R keeps the all-in-one idea of the original R7, a streamer, DAC and headphone amplifier in one compact box, but swaps the delta-sigma chip for a discrete resistor ladder DAC. That makes it an attractive way to get R2R conversion in a fully featured desktop system.
The R7 R2R has been on sale since the summer. Here is what makes it different from the original.
FiiO R7 R2R: a resistor ladder instead of a chip
Where the original R7 used an ESS ES9068AS converter, the new model uses a 24-bit R2R DAC built from 192 thin-film precision resistors. R2R designs convert the digital signal with a ladder of matched resistors rather than a single chip, and many listeners credit them with a more natural, relaxed presentation.
To keep timing clean, FiiO adds dual FPGAs and two femtosecond clocks. The converter can run in nine different modes, so you can tailor the behaviour to your taste.
Plenty of power for demanding headphones
The headphone section is fully balanced and delivers up to 4,000 mW + 4,000 mW. Five gain levels make it easy to match anything from sensitive in-ear monitors to hungry planar magnetic headphones. Outputs include 4.4 mm balanced, 4-pin XLR and 6.35 mm single-ended.
It can run on either DC or AC power, which gives you flexibility in how you power it.
An Android streamer inside
Like its predecessor, it is also a complete streamer. It runs on a Qualcomm Snapdragon 680 platform with 8 GB of RAM and 128 GB of storage, so you can install your favourite streaming apps directly. AirPlay is supported and the R7 R2R is Roon Ready. FiiO also adds AUTO EQ, control through the FiiO Control app and a remote control.
One box for the desk
The idea behind the FiiO R7 R2R is simple: one box that replaces a streamer, a DAC and a headphone amplifier on your desk. If you prefer a dedicated amplifier, FiiO’s recent Class A amplifier shows how wide the brand’s desktop range has become.
Pricing and availability
The FiiO R7 R2R has been on sale since the summer of 2026. In the United States it is listed at $879.99 at retailer Apos Audio; pricing in other regions varies by dealer. More details are on the FiiO website.
