LOVE IT - Great Performance and Great Price
Style: Stereo Receiver, Configuration: Receiver, Style: Stereo Receiver, Configuration: Receiver
Speaking as a self-described "audiophile" (but a true audiophile with deep pockets would likely laugh), this was one of the best gifts I've given to myself in recent years (as I have a fairly large music library of nearly 600 albums of 1/3 vinyl, 2/3 CDs and some cassettes).
Bought mine back in March--used to be $200, but when I saw it for $150 any hesitation went out the window and I grabbed it. I have been in love with it ever since. Fabulous sound and power (do you really need more than 100 watts per channel?), great remote control (not used to that, believe it or not), and it lives up to Sony quality. Powers my vintage components perfectly:
> MCS Series 6202 Belt-Driven Turntable (had it since early 80s)
> Nacamichi BX-300 Cassette Deck
> Sony DVP-NS725P Disc Player (DVD but used mainly for CDs - audio-only connection)
> LG TV connected via optical-to-analog adapter
> KEF Reference Series 103/3 Stereo Speakers
Interesting observation about the way the ports are labeled on the back: what would traditionally be identified as a tape deck port (with IN/OUT) is just "Input 4," and while it's connected to my tape deck for playback, the REC-OUT is connected to a USB audio adapter to digitally record anything (mostly vinyl of course) to my laptop for mastering and iPod/digital library access.
The Bluetooth connectivity is awesome as well with powerful range - great for playing music from mobile devices (phone and iPod Classic with BT adapter). The front line-in 3.5 port, identified as a "Portable" is also a great feature.
At first, I was surprised that there was no input for optical, however since digital-to analog adapters are inexpensive and readily available, I think it's best to leave it that way. Would rather have the option, rather than an optical-only port that would otherwise go unused unless one had a component that required it.
HOWEVER, if I were to make any improvements, it would be to add a USB Out port (preferably on the front), for digital recording on a PC. However again, since adapters are inexpensive and accessible, and for the price I paid for this device, I ain't gonna complain. Front level analog balance, bass and treble controls would also be nice, but you have access to all that through the menu.
If you feel due for a simple, powerful and awesome stereo receiver/amplifier upgrade without breaking your monthly budget, this is a winner.

Sony STR-DH190 is an Amazing Deal. Don't pass it up.
Style: Stereo Receiver, Configuration: Receiver
I bought my STR-DH190 receiver to put in my "man cave" pool room. I respect SONY products, but I realized this 2-channel stereo receiver was a budget item, seemingly so inexpensive it must just be an entry-point-only receiver. I was shocked by its quality, sturdy construction, versatility and audiophile sound. It has Bluetooth connectivity, and a phono input for turntables. I hooked up a CD player, turntable, reel-to-reel, cassette deck, iPod, sub woofer and two sets of high end bookshelf speakers. The fronts are SONY Sscs5 3-Way 3-Driver Bookshelf Speakers. The rears are Polk. The sound is shocking, and everyone who hears it can't believe how it rocks. Now that this receiver is actually on sale at almost a "give-away" price, I'm tempted to buy another one as a backup in case one of my other systems needs a replacement receiver. It is Bluetooth ready, so I pair an Echo Dot with it for streaming. It is an amazingly versatile and reliable product. Highly Recommended.

Quite Good, but maybe lacking a few inputs, Optical Audio and AM radio
Style: Stereo Receiver, Configuration: Receiver
Very basic, but seems to be the usual good quality Sony product. I bought this when my decades-old SOny receiver finally bit the dust.
This receiver, at a decent price is a LOT more basic than my decades-old earlier receiver. That receiver had multiple inputs-many which I didn't use but were there for audiophiles all the same. Things like inputs for DAT, inputs for MD audio. analog videos in and out, Super video in and out, Component video, standard cassette deck, phono, component video (multiple), DVD in and out, component video, and more audio channel options I can't even remember. And as old as this receiver was it actually had Optical audio as well! I REALLY wanted to replace that old receiver with the exact same thing. albeit the modern model but that doesn't exist.
SO I bought this one.
Take a look and you'll see very few inputs, but oddly it had all the ones I actually needed for my old set-up-with NO extras though. I'm kind of shocked that this receiver doesn't even have the Optical audio which is kind of a standard now for modern TVs and I had to actually buy a cheap little 'converter box' which takes the optical cable and converts the digital audio into the standard RCA analog audio and I plug that into one of the available inputs in the receiver so that I can play my TV sound through the receiver/stereo system. I'm still kind of shocked that this receiver doesn't have that Optical, that would be the first thing i'd add to really make this a bargain and much more desirable.
So I had to have a receiver for my old cassette deck, phono, etc. and standard CD player as well as DVD/Blu Ray audio sound (as concert DVDs don't sound too good on the standard speakers which come with modern TVs. So i've used EVRY input in this new unit and I really couldn't have bought it if it had a single less input.
So in addition to having an input for Optical audio the other thing I wished it had was a receiver for AM radio, even if AM isn't too popular anymore.
So maybe the lack of the Optical audio, additional inputs for other sources and no AM radio is the reason why this receiver is so reasonably priced, but well, i'm happy with it all the same.

Great product
Style: Stereo Receiver, Configuration: Receiver
This is a great basic receiver. It's very easy to understand, setup and operate. This receiver sounds excellent and includes Bluetooth so I can stream Apple Music and Spotify to the receiver. My only negative comments would be that the speaker connections are the spring-loaded terminals which require thin gauge speaker wires or Flex Pin Banana Plugs. Also, you should be aware the FM Antenna (provided) is a wire antenna utilizing a strange plug-in adapter. It was perfectly adequate for what I needed however I think it could be an issue if you were in a remote area that required a mast antenna.

Shockingly Great: Do Not Be Skeptical Of The Ultra Low Price
Style: Stereo Receiver, Configuration: Receiver
Do not allow the extremely low price on this Sony STRDH 190 stereo receiver to in any way prejudice you against considering it as a wonderful entry-level stereo receiver. I have purchased thousands of products on Amazon over the past 25 years, and I cannot think of any item that pleasantly surprised me more profoundly than this one. I also purchased the matching (style) Sony turntable PS-LX310BT which works perfectly with the STRDH 190 receiver.
Sony's lowest priced receiver now sells for the astounding bargain price of only around $200, though I caught it on sale for closer to $150... and as impossible as this is the believe, it has in recent years gone on sale for as little as $99(!) I have no idea how Sony makes a profit at these price levels.
Now I know, most people would think, "there is just no way a $200 receiver is high quality"... but I am telling you, that is dead wrong in this case, and you should prepare to be blown away by what you get at this crazy low price point.
This is NOT a no frills unit. It is feature packed.
It has connections for TWO PAIR (four total) speakers, and PLENTY of clean no-distortion power to drive all four speakers to loud and clear volume levels. It also has an A/B speaker switch to play through speaker set A, or speaker set B, or all four speakers at once.
It has a phono stage pre-amp which is actually very good. Seriously, it is much better than the phono stage pre-amp built into my Emotiva integrated amp for which I paid $1,000. It plays vinyl loud with no distortion. You will NOT need an external phono pre-amp.
It has excellent Bluetooth wireless connectivity built in... no trouble getting it to instantly recognized sources and play them perfectly. You can play all the music on your iPhone or other digital device, wirelessly.
It has a huge allotment of extra connections, ... a whopping FOUR inputs... so you can also hook up a CD player, and another external device of your choice, and another one after that, and another one after that! (WOW). And that's is not counting your PHONO input which is actually a fifth input connection. Astounding accommodation of external sources at this (or almost any) price point.
If you are a dinosaur who listens to FM ... it's got an FM receiver with 30 station presets, and an output to hook up a proper external FM antenna, and a long-wire FM antenna is included in the package
Sony says the "HiRes" audio produced by this unit is "superior to CD quality"... though I am not sure how to measure that claim, especially if the extrnal source you are using is a CD player.
It comes with a very high quality remote control, with real buttons, and many features.
You can actually program each of your external sources to appear in the illuminated display as the specific names you want, rather than a generic default source name like "CD".
The low price may raise an eyebrow, and the fairly light weight (much heavier on one side than on the other curiously) nature of the unit may also cause doubt... but only until you set it up and start listening, and your jaw drops.
I would put this sub-$200 receiver up against any receiver on the market priced under $800, (and probably several of them priced at twice that much!) and I believe you will not be disappointed in the sound quality of Sony's entry-level unit. You certainly will NEVER find another receiver anywhere near this price point with so many features and inputs... all of which work flawlessly.
This is the greatest bargain in the world of affordably-priced HiFi equipment.
It is easily worth multiple times the asking price.
