Overall Excellent - Thorough Review - READ ME
Style: Stereo Receiver, Configuration: Receiver
I'm not an audiophile per se, but I do have elevated listening preferences. I enjoy finding the value in devices, and system configs. So that's the reason I tried this more budget-friendly receiver.
Aesthetics: The look is very sleek and modern, which is great but sometimes I miss the nostalgia of more knobs. There is no base/treble knob and most everything is controlled by remote. That's fine I suppose, just be aware. The volume knob is very large and traditional which I love, but is also very stiff and not buttery smooth like you might expect. Perhaps that will break-in.
Sound Quality: Wow, this sounds incredible. There is definitely a DSP happening that is noticeably awesome. It's referred to by Sony as Pure Direct. If you want to by-pass this, you can, but you'll hear right away the difference is major. I'm using simple Klipsch bookshelf speakers, and my expectations are surpassed on how much they come to life with bright and rich sound. Definitely a nice pairing for those shopping for speakers along with this unit. Overall the SQ is gonna be tough to beat without spending exponentially more.
Remote: The remote is nice, sleek, and has what you need to quickly access. No complaints there.
Installation: Takes minutes, super easy. Didn't follow any instructions due to my general confidence hooking up home audio gear.
Overall: I highly recommend this one, and I'm picky. Initially, I fully expected to return this receiver, but plan to keep it. The only thing that may change my mind, is if I miss the nostalgia... then I'll have to go vintage. But no way a vintage receiver will sound this good. Props to Sony. Well done :)
A+

Nice amplifier for the cost.
Style: Stereo Receiver, Configuration: Receiver
I had been using my Marantz model 22 receiver now for a couple years now with the TV, dvd player, and youtube music from my tablet. I like lots of knots and switches on my audio gear, I'm an engineer. I was getting tired of the seemingly endless up and down to adjust volume and whatever. And my inputs on the Marantz were maxed out. I searched Amazon to see what was available as a possible replacement that had a REMOTE. This Sony caught my eye. Relatively inexpensive, plenty of inputs, and specs I could trust, not a 3x4x5 box offering 220+220 watts of unlimited power! Ordered it and been using it for over a month now. Only 2 knobs, how good could that be? Well, it's remote let's me control everything without getting up. Plenty of output power, 100+100 watts of true RMS power. I didn't plan on using the Bluetooth but I tried it with the tablet, keeping the tablet by me, and it really impressed this old audiophile. I really don't have any negatives about it, even the fm sounds great. It was heavier than expected but not as much as that old Marantz. I even popped the cover. The build quality was what I consider good. I only wish I could find a service manual with the schematic for it.

Great Banana Plugs
Size: 6 Pairs / 12 pcs
I recently purchased these FosPower banana plugs to tidy up my speaker wiring, and they’ve been a significant improvement over bare wire ends. Installation is straightforward: strip the wire, loosen the two tiny set screws, slide the wire in, tighten everything down, and then screw the barrel back on. Once assembled, the connection feels secure and tight, making it much easier to swap gear around and reducing the risk of stray strands causing a short.
The standout feature of this design is the dual set-screw clamp. It firmly grips the speaker wire without relying on the outer collar to “crush” it in place. I’m using 12-gauge wire, and it holds well for my setup.
Initially, the plugs may fit snugly in some binding posts. Once seated, there’s no wobble, but it might take a bit of extra push the first time.
The set screws are small, so a bit of precision is needed. Use a small flathead screwdriver and don’t over-tighten them.
Overall, these plugs feel well-made, look clean once installed, and fulfill their purpose as banana plugs: making speaker connections quick, neat, and reliable.

Great Banana Plugs!
Size: 6 Pairs / 12 pcs
These FosPower banana plugs work very well. I have used dozens of these great FosPower banana plugs over the years, and they definitely work as advertised. When comparing apples to apples (or bananas in this case....lol), all Banana plugs work virtually the same way, and these banana plugs are no different. Strip speaker wire, unscrew banana plug cover, loosen speaker wire retaining screw(s), insert speaker wire, tighten speaker wire retaining screw(s), screw on banana plug cover, and wallah, a secure/conductive speaker/amplifier wire connector is created. Albeit, some banana plugs require the speaker wire to be splayed over a hollow post, and then they are held down by a screw-on retainer/cover. However, I much prefer these FosPower dual retaining screw type of banana plugs for their speaker wire holding ability.
I always use high quality 14 gauge OFC speaker wire with these FosPower banana plugs, and they work perfectly together. I have used these FosPower banana plugs with many different speaker and amplifier brands over the years, including Klipsch, Pioneer, Polk, Denon, Dayton Audio, and Fosi with no problems at all. They just work, and work well. I have never had a FosPower banana plug break, release the speaker wire or short out, in all of the years that I have used them.
Yes, these FosPower banana plugs do fit rather tightly into the connectors, at first, on a lot of speaker and amplifier brands/models. However, after the initial "squeeze" the banana plugs will lossen up, and become easier to install and remove. However, they still retain their great holding ability even after the initial squeeze. In order to overcome this initial "tightness," I usually just stick the FosPower banana plugs into a connector of an old portable amplifier, before assembling them, in order to squeeze them before inserting them into their final speaker or amplifier destinations. This is especially useful when working in tight places, where there is not much room to work in order to push the FosPower banana plugs into their tight connections firmly.
Overall, I highly recommend these FosPower banana plugs. I am currently using them all over the house and shop for home theater and music listening (and testing projects). Just be aware of the tight fit in some speakers and amplifiers. Also, the 2 very tiny speaker wire retaining screws can be a challenge sometimes. Just use a good standard blade jewelers screwdriver, and be careful not to remove the retaining screws all of the way or over-tighten them. Once these things are mastered, using these FosPower banana plugs becomes second nature. Have fun!
