Yamaha has announced two new streaming components, the WXA-70A amplifier and the WXC-70A streamer. The amplifier is the interesting one, because it replaces the WXA-50, a little box from 2016 that people are still cross-shopping on this site today. The WXA-70A is in our database now, with the full specs.
Yamaha WXA-70A streaming amplifier
Quick facts
- 55 watts into 8 ohms. Same as the WXA-50 it replaces.
- About $1,300, or GBP 1,199. The WXA-50 launched at $599.
- HDMI eARC and YPAO room calibration are the real additions.
- 220 x 73 x 267mm, 2.6kg. November.
Some of the early coverage says the WXA-70A makes 70 watts per channel into 8 ohms. That number does not appear on Yamaha's own spec sheet, and it matters enough to start with.
Yamaha's own spec sheet says 55 watts, not 70
Here is what Yamaha lists for the 120V and 230V versions, which covers both the US and the UK: 55W + 55W into 8 ohms, 20Hz to 20kHz, 0.06% THD, both channels driven. Into 4 ohms it makes 105W + 105W on the same terms.
Now compare that with the WXA-50, straight from our database entry: 55 watts into 8 ohms, 70 watts into 6 ohms, 105 watts into 4 ohms, and the same 0.06% THD over the same bandwidth. The two amplifiers are identical at 8 ohms and identical at 4 ohms.
Where does 70 come from? Probably from the 100V Japanese model, which Yamaha rates at 70W + 70W, but that is into 4 ohms, not 8. It is an easy line to misread on a spec table that lists three regional variants in one paragraph. If Yamaha revises the sheet later we will update our entry, but as things stand today the number is 55.

Yamaha WXA-50 the model it replaces
Nine years apart and the amplifier section makes exactly the same power. Everything you are paying the extra money for sits around the amplifier, not inside it.
What the extra money actually buys
That is a real list, and it would be unfair to pretend otherwise. The WXA-50 was a 2016 product and it shows in the feature set more than in the wattage.
- HDMI with eARC and ARC. One cable to the TV, and the TV remote controls the volume. The WXA-50 had no HDMI at all, which was its single biggest limitation as a small living room amp.
- YPAO room calibration, with the measurement microphone in the box, plus Reflected Sound Control and YPAO Volume. The WXA-50 had no room correction of any kind.
- Streaming protocols the WXA-50 never got. AirPlay 2, Google Cast, Roon Ready, and Qobuz Connect and TIDAL Connect alongside Spotify Connect. Our WXA-50 entry has "No" against AirPlay, Chromecast, Roon and Qobuz, and that gap has only grown more annoying over the years.
- An ESS SABRE ES9039Q2M DAC, an OLED front display, an aluminium enclosure and gold-plated speaker terminals.
- Installer plumbing: a 12V trigger out, an IR remote input, and a browser-based setup page. Yamaha is clearly aiming this at custom installers as well as at people buying one for the den.
- A Dialogue Level control, which lifts speech without raising everything else. Sensible on something you will connect to a TV.

What you still do not get
The back panel is worth a proper look, because it is smaller than the feature list suggests.
- One analog input. A single stereo RCA pair marked AUX IN. The WXA-50 also had one. If you own a turntable and a CD player, you are one short.
- No phono stage and no headphone jack. Neither did the old one, but at $599 that was easier to forgive.
- Optical in, but no coaxial digital in. Again the same as before.
- Rated 4 to 8 ohms, printed on the back panel. Difficult 2 ohm loads are out.
- Bluetooth is SBC and AAC only. No aptX, no LDAC, in 2026.
- It got bigger. 220 x 73 x 267mm and 2.6kg, against 214 x 52 x 267mm and 1.95kg. Mostly it grew upward, by about 21mm, so if you were sliding a WXA-50 into a tight shelf, measure before you order.
Where it lands against what readers actually compare
This is the part we can speak to that a press release cannot. Nine years after release, the WXA-50 still sits in the top half of the 193 amplifiers that get compared on this site, which is not where a discontinued 2016 box normally lives.
More useful is what people put it up against. Just two rivals account for over a quarter of every WXA-50 comparison run here: the Bluesound POWERNODE Edge and the Sonos Amp. That is the shelf the WXA-70A has to fit on.
And here is the one that surprised me. Nearly four in ten WXA-50 comparisons are against Yamaha's own A-S integrated amplifiers, the ordinary ones with no streaming in them at all. People are not only asking "which streaming amp", they are asking "streaming amp or a plain integrated". At $1,300 the WXA-70A walks straight into a fight with real Hi-Fi separates, which the $599 WXA-50 never had to have.
Read that table and the WXA-70A is the most expensive thing on it and one of the least powerful. The WiiM Amp Pro has more power into both loads, HDMI, room EQ and Roon Ready for less than a third of the price. That is the comparison Yamaha has to answer.
The honest answer is probably build, tuning and support rather than any line on a spec sheet, and that is a legitimate thing to pay for. YPAO is also a more serious room correction system than most of what is in this class, with a proper measurement mic rather than a phone. But nobody should buy this expecting it to go louder than the box it replaces, because it will not.

If you already own a WXA-50
Short version: there is no power reason to upgrade, so ignore that side of it entirely and ask what you actually want.
Upgrade if you want to run your TV into it over HDMI, if your room is awkward and YPAO would earn its keep, or if you have wanted Roon or AirPlay 2 for years. Do not upgrade if the WXA-50 is a second-room or desk amp fed by Spotify Connect, because in that job the new one does nothing the old one does not, for around $700 more.
Both are in our database, so you can put the two side by side and read every line yourself. Here is the short version.

One more thing worth doing before you buy any 55 watt amplifier: check it against the speakers you own. Our amp and speaker matcher takes the sensitivity and impedance of a speaker and tells you whether a given amplifier has enough in hand for your room. 55 watts is plenty for most bookshelf speakers and a fair number of floorstanders, and nowhere near enough for a few.
The streamer version, briefly
The WXC-70A is the same idea with the amplifier taken out. It is a network streamer that plugs into an integrated amp or receiver you already own, with the same MusicCast app, the same streaming services and the same TV connection. Reported pricing is around $1,000 or GBP 859. We do not hold streamers without amplification in our database, so it will not be getting an entry here, but it is the obvious choice if you already have an amp you like.
Questions answered
Is the Yamaha WXA-70A more powerful than the WXA-50?
No. Yamaha's spec sheet for the 120V and 230V models gives 55W + 55W into 8 ohms and 105W + 105W into 4 ohms. The WXA-50 was rated at exactly the same figures. Some early coverage quoted 70 watts into 8 ohms, which appears to be a misreading of the 100V Japanese model's 4 ohm rating.
What does the WXA-70A add over the WXA-50?
HDMI eARC and ARC, YPAO room calibration with a microphone included, and a much better streaming list: AirPlay 2, Google Cast, Roon Ready, Qobuz Connect and TIDAL Connect. It also gets an ESS SABRE ES9039Q2M DAC, an OLED display, an aluminium case, a 12V trigger and an IR input.
How much does the Yamaha WXA-70A cost?
Reported pricing is about $1,300 in the US and GBP 1,199 in the UK, with availability from November. Yamaha USA has not posted a price on its own product page yet. For reference the WXA-50 launched at $599.
Will the WXA-70A drive my speakers?
It is rated for 4 to 8 ohm loads, so anything dipping to 2 ohms is out. For everything else, 55 watts into 8 ohms is comfortable with most bookshelf speakers and a lot of floorstanders. Run your own pair through our amp and speaker matcher rather than guessing.
Is the WXA-50 discontinued?
It is no longer listed in Yamaha's current Hi-Fi components range and the WXA-70A is presented as its successor. Our review page and full specs for the WXA-50 stay up, because plenty of them are still in use and still turning up second hand.
So is it worth it
As a product, the WXA-70A is good. HDMI, YPAO and a modern streaming stack fix nearly everything that had started to date the WXA-50, and it is still small enough to put almost anywhere. As a replacement, it asks a lot: more than double the price for identical power, in a class where a WiiM Amp Pro now does most of the same tricks for $379.
If Yamaha had held it nearer $900 this would be an easy recommendation. At $1,300 it needs the YPAO and the build quality to be genuinely worth the gap, and nobody can tell you that until units are in rooms.
What would you spend $1,300 on instead, and would room correction change your mind?
