Sony STR-DH190 Stereo Receiver

Lifewire / Jonno Hill

Clean looking design

Flimsy speaker terminals

The Sony STR-DH190 is an admirably performing entry-level stereo receiver that sounds great in spite of its price.

Sony STR-DH190 Stereo Receiver

Lifewire / Jonno Hill

Shopping for a stereo receiver can be a frustrating, complicated, and above all else, an incredibly expensive endeavor, but the Sony STR-DH190 offers a much-needed respite. It’s lacking a lot of features you find in more expensive receivers, but by focusing on the bare essentials Sony is able to offer a very compelling product for unfussy buyers that just need to get sound moving to their speakers without blowing their entire budget.

What you lose are largely creature comforts—things like HDMI inputs/outputs (and therefore HDMI ARC compatibility), Wi-Fi and Ethernet functionality, Alexa / Siri / Google integrations, preamp outs, subwoofer outs. Okay, maybe a lot of those aren’t creature comforts to a good deal of shoppers, but I don’t imagine the STR-DH190 was very high on their list to begin with.

You do still get plenty of great features however, like phono inputs with proper pre-amp, Bluetooth connectivity, the ability to connect two sets of speakers, and a very generous 100W per channel of power. Is this enough for the price? I sure think so, but let’s unpack the rest of the features to see if it has enough to suit your needs.

Design: Minimalistic and premium looking

I’m a big fan of the design of the Sony STR-DH190. Its minimalistic exterior somehow makes it look a lot more expensive. Sony didn’t need to overcomplicate the design of course because there aren’t a tremendous amount of features to make buttons for, but this same design is mirrored in a lot of their more expensive, feature-rich products as well. I’m inclined to believe it’s just a design choice.

On the front of the device you’ll see a large volume knob next to a smaller input selector knob, and opposite these, a 0.25-inch headphone jack and an 0.125-inch “portable in” port—handy for playing audio from your phone, computers, and plenty of other devices. There is of course a button for Bluetooth, and a button to toggle between either set of speakers or both.

Its minimalistic exterior somehow makes it look a lot more expensive.

The back of the Sony STR-DH190 is similarly modest. Up top, there’s room for an FM antenna (included in the box), and a USB port for service purposes only. On the bottom row, you’ll see the phono in jacks for connecting a turntable, the 4x audio in jacks and 1x audio out, and the speaker terminals. Unfortunately, Sony uses flimsy little spring-loaded terminals that can’t accommodate banana plugs, and only narrowly fit the pin-type tips that I had handy. As long as you keep this in mind, and use 14 gauge speaker wire or smaller you should be fine. It’s likely just easier to cut and strip your own wire.

Setup Process: A breeze to get started

Thanks in no small part to the relative lack of extraneous features, setup is a breeze. Connect your speakers to the speaker terminals using your (hopefully by now) cut and stripped speaker wire. Next connect your audio sources to your receiver, making sure to use a phono cable with a ground wire if connecting to a turntable. Power the STR-DH190 on, and you’re listening to music. This is a delightfully simple setup process when you’re used to testing much more convoluted stereo equipment.

One note on Bluetooth—everything is handled through the single button on the front of the device. Press it once to enter pairing mode if there is no previous pairing information on the receiver, and press it once to connect to the last connected device automatically as well. If you’re already connected, pressing the button will disconnect the device. The remote itself has a Bluetooth button and a separate dedicated Bluetooth pairing button.

Sound Quality: Hard to find any issues

The Sony STR-DH190 is somewhat of a marvel for its price. It’s hard to find too many faults with the sound quality on this receiver. I tested using two pairs of floor-standing speakers: The Dali Oberon 5 and the Klipsch RP-5000F. Running it through the gauntlet of music from the intimate solo piano works of Nils Frahm to the tightly produced electronic music of Oliver, the STR-DH190 kept pace nicely, able to express the nuances of each track with relative ease.

Not only that, but the Sony STR-DH190 gets quite loud, thanks to the 100W of power per channel. I got into noise complaint territory a long time before I came anywhere near 100W per channel, but if you want the extra power it’s there.

Features: The bare essentials

The Sony STR-DH190 isn’t brimming with features, but there are still a few things of note. One handy feature that the receiver has is the ability to turn on from a paired Bluetooth device, like your phone, even if the receiver is in standby mode. Just a small quality of life improvement so you don’t have to go searching for the remote or walk over to the receiver every time you want to start listening to music.

You might also notice a “Pure Direct” button on the front of the device and the remote and wonder how it improves sound quality. Don’t get too excited—the only thing that it does is turn off the display lights “to suppress noise that affects sound quality”, and disable any EQ adjustments made to the bass and treble. This has been a feature on receivers for a long time now, and a hotly debated one.

One omitted feature that is sure to bother a lot of people is the lack of a dedicated line-level subwoofer output. You will still be able to connect to some subwoofers using speaker wire and the second set of speakers terminals in the back of the Sony STR-DH190, but certainly not all. This will limit the number of subwoofers you can seamlessly connect to, as many don’t have speaker wire terminals. Check out our article on how to connect a subwoofer to a receiver to learn more.

Price: Absolutely unbeatable

At an MSRP of just $129, price is one area where the Sony STR-DH190 is absolutely faultless. This is more than the amount of receiver I would expect to get for under $150. Sure, I could talk about all the little things I wish it had, but it would be fairly unreasonable to do so. The STR-DH190 is a great deal for the amount that it costs, full stop.

Sony STR-DH190 vs. Onkyo TX-8140

Another among the receivers that we tested was the Onkyo TX-8140 (see on Amazon), which at an MSRP of $299 is more than twice as expensive as the Sony. So what do you get for more than double? You don’t get more power, as the Onkyo is rated at 80W per channel instead of the Sony’s 100W. You do however get Wi-Fi and Ethernet support, additional stereo inputs, two coaxial ins, two optical ins, and a subwoofer out. That’s a significant amount more connection options, but boy is it also a lot more money, so you better really need them.

Overall, I preferred the sound of the Sony STR-DH190 a little more, but just marginally so. The Onkyo is a perfectly fine receiver, it’s just a little hard to justify it when up against the absolute bargain in Sony’s corner.

One of the best receivers for under $200.

The Sony STR-DH190 may offer a rather baseline set of features and connectivity options, but it does a great job at every one of them. It’s a beautifully minimalistic looking receiver that sounds great and gets the job done without any fuss. If you don’t have a huge budget, or any requirements beyond what this receiver can offer, it’s a winning choice.

Sony STR-DH190 Stereo Receiver Reviewed

Founder/Admin

This is a review and detailed measurements of the STR-DH190 stereo amplifier. I was talked into buying it to review a while back. The STR-DH190 costs an incredibly low US $140 from Amazon including free shipping! The economics of this is impossible to fathom. If I had to sell you its empty box I could not make a living at this retail price. So I imagine Sony is losing money on every one of these.

From the outside, the STR-DH190 looks like a smaller version of Sony AVRs with a rather elegant look:

I did not expect a full display and microprocessor to drive it but that is what we have. Likely because this is a featured AVR. Everything looks great until you touch the volume control and realize it is a stiff feeling thing, best left to look at than use. Fortunately a remote control is included so you can do exactly that.

You even get a radio and phono stage in this thing. And even a button named «pure direct» which did nothing but turn off the display.

The back panel shows the connectivity you expect in an analog amplifier:

I hated the spring loaded speaker terminals as I could not stuff my banana plugs into it. But hard to complain too bitterly at this price. Ditto for non-removable cord.

There is a «hot» symbol on top of the amp for a reason: even at modest output power this thing gets really warm and toasty on top. For this reason, and wanting to pass UL certification with respect to heat generated, Sony only specs the STR-DH190 for 6 ohm speaker load and higher. Don’t worry, it works «fine» at 4 ohm as well as my measurements show.

As a sign of corners being cut to save money, notice how the rear feet are just the chassis bulge with a tiny little pad. The front feet that you do see are proper round plastic ones! Reminds of stainless tips on car exhausts to make you think the rest is made the same way.

Amplifier Audio Measurements
Let’s run our dashboard with 4 ohm load and 1 kHz tone and see what happens:

Typical power supply ripple is visible which we see in many amplifiers. I wish both channels were as good but they are not with one having good bit more distortion than the other. Averaging the SINAD for both channels lands the STR-DH190 in the middle of all amps tested with this metric:

Signal to noise ratio is «OK»:

Frequency response measurement had me stomped for a while because it was anything but flat. There is no eq in this thing so what could it be? Then I realized it was the amplifier that was reducing power after a few seconds even though I was just running it at just 9 watts or so! You can see that in the top graph:

The sweep starts from right and goes to left and hence the reason you see the drop there. Running the same test with 5 watt output didn’t cause that problem. But showed the same persistent rise in low frequencies.

32-tone test track shows what we already know as far as distortion floor:

At low frequencies power supply complains with rising ripple causing those spikes between our tones. At high frequencies the amp runs out of gain-bandwidth so distortion naturally rises some.

Most important here is the power versus distortion and noise so let’s look at that with an 8 ohm load:

We just shy of the 100 watt rating of the amplifier which is fine.

With 4 ohm load we get lots more power still:

Again, wish one channel wasn’t acting up but otherwise, we have lots of power here.

We can even get more if we measure max and peak power with 1% distortion into 8 ohm:

Couldn’t run this test at 4 ohm because the amp would either shut down or when I reduced the level, not achieve 1% THD. More on this in a bit.

THD+N versus level and frequency shows orderly response, had it not been due to each channel acting differently:

At this point, I decided to run the 20 to 20 kHz power sweep, regulating the output to 1% THD. This involves the analyzer at each frequency point, raising and lowering the input level until distortion equals 1%. I kept failing to get there at all frequencies with the amp shutting down or not getting to high enough distortion. Needing to play with the parameters a lot, I put a fan on top the amplifier heatsinks and kept playing around. Next thing I know, it shuts down but no longer powers up. The power LED lights up but the rest of the display does not. And after about 8 or so seconds, it shuts itself down.

Left it to cool overnight but this morning still does not power up. Nothing is smoked in there but there is a smell of burnt varnish which points the finger likely at the power transformer.

Conclusions
Lowing our lofty standards good bit, the Sony STR-DH190 seems to be a good amplifier. It looks nice, has remote, multiple inputs, phono, etc. and produces a lot of power. It is certainly much better than a lot of Internet specials when it comes to amplifiers. What you pay for it gets you headphone amplifier and that is it. The value is therefore remarkable.

The beheaded pink panther is making a showing here naturally due to the unit failing. The protection circuit should have saved this product but it did not. Likely it doesn’t look to the power supply getting overburdened. Now I have to figure how to get this unit serviced. If they tell me to ship it to them at my expense, that will be the end of this journey as it wouldn’t be worth the cost or aggravation. We do have a Sony repair center about 40 miles from here but who wants to drive back and forth and wait for who knows how long to get this fixed?

Of course, I waited months to test this so can’t return it to Amazon where I bought it.

I suspect none of you will stress it to the extent I did though. As a back up if you drive it hard, you may want to get one of those fan coolers and put it on top.

No recommendation one way or the there. You have the data to decide.
