Very good audio receiver for my tower speakers and record player set up
Style: Stereo Receiver, Configuration: Receiver
I have had my 1980s Roger sound lab CG 82 Tower speakers connected to a 1999 Technics audio receiver. I use this set up for Radio and my record player. After many good years, the low end on my audio receiver gave out. I have had it serviced before, but I have owned it for five years and it is a 27-year-old piece of gear that has seen better days. ChatGPT led me to this receiver. It took me less than five minutes to connect my speakers. What I love about this receiver is that it’s so simple to use. The radio signal is very good right out the box without an additional antenna. I was resistant to buying a Bluetooth receiver, but it connected to my iPad and my iPhone in seconds. Now I can play backing tracks through my Roger sound lab speaker speakers while I jam out on guitar. No issues with sound quality or anything like that. Runs cool and quiet. If you are a total audio file, you could buy something more expensive. I am a musician and I listen to vinyl. Mostly jazz and classical, and this is fine for my needs. For most people running a record player, looking to modernize with a Bluetooth enabled receiver, this will suit your needs.

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.
