Sunbuck Small Stereo Amplifier, Stereo Receiver with Bluetooth, Optical/Coaxial Jacks for TV/CD/DVD/LP/PC, Support 192kHz Audio, Max 300Wx2 Power, Home Audio System, Receiver for Speakers, AS-25BU

Surprisingly good for the price. The only thing missing is a headphone jack but...it's a little power house and well drives my bookshelf speakers. It has presets and the Bluetooth connects easily and as expected. I'm going to mount this under a top cabinet in the kitchen. Don't expect much from the manual as it is written in very broken English but you can still figure it out. It also comes with a standard AC cord so you don't need to fuss with a DC wall wart. It comes with a small remote as well. You can't go wrong for the price. FYI - In the rating questionnaire it asks about "Sheerness". I have no idea how that applies here. P.S. - I have a few additional comments regarding this item after reading some of the other reviews. 1. Quality - some folks have had issues after running the system. Since my review was written days after receiving it, I can't comment except to make sure you put it in a location where airflow to the unit is not blocked. So far, my unit is not getting hot. 2. Sound quality - Folks, this unit costs $45 dollars. If you are and audiophile and into studio quality sound, then I think you are expecting a bit much for $45. I'm a music lover and it sounds plenty good enough for me. I've listened to YouTube music videos and some FM music stations and it sounds pretty good to me. It does go louder than I need and I get some decent full bass sounds from my bookshelf speakers. If you expect 130 db rap or pounding rock or the fine nuances and dynamic range of the 1812 Overature, then this unit might be for you. But aside from the long term potential quality issue, I'm quite pleased with the unit. If you are happy with the quality of music over your cell phone, this will do just fine and my wife is happy listening to Bocelli over this unit. So, since I've already belabored this issue, I'll repeat, for $45 you get a very small unit that sounds pretty darn good. Oh, and yeah, the controls seem a bit weird at first but since the unit is small, 20+ buttons simply won't fit on it so they've overload some of the buttons with more than one function which is not big deal after 10 minutes of acclimation. And then there's the remote. The first time I tried it didn't work either but just press the button a tiny bit firmer and it works fine. Lastly, if you plug this into cheapo speakers, it will sound crummy. Buy a $1000 receiver and plug it into a $99 dollar speakers, it'll sound lousy. So make sure your speakers match your sound expectations. The End

I purchased the "Sunbuck Wireless Bluetooth Stereo Amplifier System – 180W Dual Channel Sound Power Audio Receiver w/USB, SD Card, FM Radio for Home Speakers (25BU)" after reading reviews and finding the features ideal for my home installation. It has a very small footprint which is ideal where space is at a premium. Controls are simple and intuitive. Knobs for volume, bass, and treble operate smoothly and precisely. The remote works well, but its diminutive size will encourage getting lost. I find the connections and construction to be of surprising quality for such a value added amplifier. I drive two Wharfdale Crystal 10 bookshelf speakers, which it handles with ease. My inputs include a CD player and Bluetooth sourced from my phone. Sound quality and Bluetooth connectivity are excellent. It would be nice if the antenna was a post style rather than the wire style, as FM reception might be improved. Speaker connections are of the spring loaded variety and grasp wires securely. USB and SD inputs are nice although I have yet to utilize them. The unit is very attractive with a screen and volume illuminated by a neon blue hue. All in all, the amplifier is a very nice surprise and exceeds my expectations. I can't speak yet to longevity at this time, but hope it is of equal quality. I should mention that the Sunbuck and Pyle brands appear to be related, as the equipment is identical with the exception of branding. I would definitely purchase these products again in the future and recommend them without reservation.

I bought this to power some extra bookshelf speakers I have in my basement shop. My speakers are wired back to this unit. I connect to the unit either directly from my phone via BT (connects fast and works reliably) and I have also have banana plugs (1 to 2) running from the output of my Alexa echo to this unit. So I can either tell Alexa what to play and it plays through this unit by switching the input, or via my phone's BT. My speakers aren't great, so it's hard to comment on the power delivery or sound qualiity, but it's decent for my use. The only thing I don't quite undertsand, and which would be helpful, is to have it mountable. There are rubber pullout handles on the front, similar to what you'd expecte from a rack-mountable unit, but I don't see any way to rack-mount this, or even a housing small enough to do so.

Excellent investment if you're the guy who needs tunes in shop and doesn't want silly wireless, must be recharged speakers. Hang up regular wired speaker's in your shop or garage. Buy this and you'll be set. Fm radio,or play tunes from phone via Bluetooth. The remote actually works and quite well. The cons: the blue screeb is extremely hard to see or read from more than a few feet away. The remote is extremely thin and cheap- be careful. Will this thing produce 180 watts...No way and not even close. I'd guess 40-50 watts and that's more than enough to power and few speakers in a shop. The unit itself- clearly cheap and built cheap. It's a set it and use when needed item. Will last a long time. Oddly you have a two power options. Power off on remote leaves volume light on. Power switch on back of unit shuts entire thing down. I tested this thing tonight as I was looking forward to it and it honestly met my expectations. I like it. As a bonus. I managed to walk about 40 feet away with phone in hand before Bluetooth connection dropped. Nice.

I really wanted to love this thing. It's so cheap, and it has so many features, but the implementation is . . . odd. For example (and I have several examples), there's a power switch on the back of the unit (on the BACK?) and a power on/off on the remote, but the remote will just turn off the sound; the unit is still lit up. And the remote can't do anything if the power switch on the back is off. Most irritating (so far) is the volume control. There's a knob on the unit and two buttons on the remote, but the remote can only turn the volume up to where the knob is set, and if you power off the unit, it forgets where you've set the volume using the remote, so it can suddenly turn on startlingly loud. At this price, I'd assumed it was a Class D amplifier, but it's larger & heavier than the little Class D amps I've seen, and it has a lot of ventilation holes, so there may be some A/B going on. The vent holes make it less-suited for outdoor use, which is where I'd intended to use it, but not a problem inside and still much smaller than a traditional receiver. It sounds good, and the bass & treble adjustments are particularly useful with cheap speakers. Much later: I was using this in my garage and I decided to upgrade to a Douk Audio ST-01 Pro, which isn't high end but it's certainly well-respected and costs 3X the Sunbuck. Out of curiousity, I set them up for a fairly rigorous comparison using a switch and a good set of speakers (Elac Uni-Fi 2.0), and using USB drives as the sources for both amps. The Douk looks much cooler and is less irritating to use, but for sound quality, the two were very, very close. I thought the Douk was a slightly richer, particularly with female vocals, but I may have been fooling myself. So, sonically, I think the Sunbuck is surprisingly good and punches way above its price.

I bought this amp in an experiment to create the lowest cost possible studio monitor setup. Most audiophiles in the music mixing/production world would scoff at my creation. I often shop at consignment stores in my city where I always can find old speakers for next to nothing. In this case I found 2 speakers, made by Sharp. 4 ohm 100w/200w max each. I gave $2.12 each for them btw. I bought the AS-25BU amp for the left and right inputs in order to send signal from my audio interface. I cannot believe how crystal clear the sound is. I had to shape the sound with the bass and treble knobs until it equaled the tone of my nice studio headphones. Sending 90w to each 100w speaker is like magic. I can crank the volume up without once ounce of hiss from the speakers. I now have convincing looking studio monitors that give me the clarity I need in mixing tracks outside of my headphones. This thing gets incredibly loud. Plus: FM radio and Bluetooth to boot. Super happy customer.

I had high hopes for this product. Just wanted an inexpensive amp to play music in my garage. First of all, SD Cards and USB drives must be formatted for PC. The documentation does not tell you that. After reformatting drives I transferred my music from iTunes to the card, hooked up the unit and started to play. All sounded good. However, out of the 304 songs I loaded it only played the same 9 songs over and over. After an hour on the phone with Amazon tech support and 3 hours of experimenting, I discovered the unit only plays MP3 files. It doesn't play M4A, M4P or AAC files. iTunes will not convert these to MP3 because of DRM. I even downloaded a 3rd party converter from the App Store. 2 hours later, it wouldn't convert them either. To further experiment I took the unit in the house, when I went to connect the speakers one of the flimsy connectors broke. I returned it to Amazon.

I didn't pay much attention to the size when i ordered it and was taken aback when i saw how small it was. I went ahead and hooked it up anyway and was just literally almost blown off my stool! The volume is defaulted at 30 (max) and my head was inches away from my old "boombox" speakers. I looked at my little girls on the ground about 10 feet away and they had their ears covered! Small little unit packs a serious punch. Like other reviews the bass is a little lacking, however, that doesn't bother me in the least. One of the selling points for me on this was the remote control. That works great. Another was the fact that it has a tuner, aux and bluetooth. All work great with not issues. If you still use CDs then there is a hookup for that as well. You absolutely cannot beat this little unit. I only paid $40 but i feel it's worth much more.

Ich habe dieses Gerät als Radio in meiner Werkstatt im Einsatz. Das Anschließen zweier Hifi-Boxen hat problemlos geklappt. Der Receiver läuft seit Monaten ca. 10 Stunden täglich. UKW-Empfang, Klang, Rauschverhalten, Verarbeitungsqualität - alles ohne Beanstandung. Positiv ist auch, dass das Gerät ein internes Netzgerät und einen Ein-Aus-Schalter hat. Leider ist das Netzkabel recht kurz. Etwas lästig ist, dass nach jedem Einschalten die "Line"-Funktion aktiv ist und man erst noch eine Taste drücken muss um in den Radio-Modus zu schalten. Aber ansonsten ein nützliches Teil mit vielen Möglichkeiten, das ich wieder kaufen würde.

Ottimo prodotto per ascoltare musica e audio collegando diversi dispositivi . Comodissimo il telecomando. Materiale non eccellente ma fa il suo lavoro .

Buona la resa del suono in generale. Il led luminoso sulla manopola del volume è troppo forte e disturbante.

Mejor de lo que esperaba, funciona fenómenal
