Title: Very good and affordable amplifier for bookshelf speakers
Review: This is a tiny amplifier but it is capable of delivering substantial power thanks to its class-D technology. Sound fidelity is quite good. Easy to setup because of bluetooth. I use it with my 6-ohm Peachtree speakers (which are not particularly efficient) placed on my desk. For this arrangement output volume is more than enough. Built quality is good for the price.

Title: great little amp. does the job nicely
Review: i got this to replace the final stage on the sony amp that blew it's left side. the sony still works as a preamp and switcher for the turntable, tv and music streamer i have so i didn't have to redo a lot of wiring. all i had to do was run a line from the tape-out on the amp and move the speaker wires to this little guy. all my controls and remotes stayed the same. nice bonus is i now also have bluetooth. it's not as powerful as my original amp and you can't drive it as hard; ive a feeling if you do, something will blow as the components are rather small. it happened on another, similarly built amp. the sound quality is adequate, esp in this age of earbuds. my wife doesn't notice but i can definately tell there is a midrange bias, even with the tone controls. still, it's good for it's size.one thing i really like is the bluetooth addition. the sound quality is good and there is very little spurious noise. it is a preferential connection so it will override anything coming in from the AUX inputs. i wish there was a button to switch but as is, just turning off the bluetooth on your phone will cause it to automatically switch back.overall, it's a good little unit. i wish it were closer to a $60 price point but build quality seems good and sound quality overall is great for this little guy. i'll probably buy another one to use as a portable outdoor entertainment like another reviewer did.

Title: For once, I am thrilled with a purchase
Review: As a consumer aI am rarely impressed and thoroughly satisfied with a purchase. I rarely write reviews.This little gem is impressive. First of all as someone who has traversed the analog and digital realm, this is very throwback in its simplicity. Power, treble, bass, volume. Thank you! The casing is metal and great. The size is also desirable.Here is where this amp shines… I live in the audio and visual world. I have worked with very high end speakers and products. How did this amp manage to make my 90’s Sony Megabass boombox speakers(I ran this amp as a midway point between the Boombox and speakers) anyway how did it manage to make those speakers sound like 1000 dollar bookshelf speakers?! I kid you not. I was fully expecting the speakers to not be able to handle the output of the amp considering they are only rated to like 20 watts or something. But I can crank this amp and it makes those speakers sound absolutely stunning. So much so I felt compelled to hook it up to more expensive modern speakers and while they also sounded incredible, the old Sony speakers shined. Perhaps that is also a testimony to how the CFD-758 speaker housings were designed.Anyway… this amp is wonderful. Worth every penny. In fact I would have been happy to pay nearly double.

Title: Way decent little amp!
Review: I like that I have very easily paired my phone with the Bluetooth on this little amplifier.I use it with the “headphone out” of my Roku remote and it works impressively well. It’s a very full, quality stereo sound :-)Depending on your gauge of speaker wire, there’s no need for banana jacks.

Title: Great little unit
Review: This little unit is surprising. The sound is clean. No hiss or buzz as advertised. The case is metal not plastic. The adjustment knobs are smooth and have a feeling of quality. The BT connection has been solid so far. Over all I am very impressed and would recommend this to anyone looking for an amp for your BT music or a computer sound system, or a workshop or patio.

Review: Works great, nice quality machining on the finish. Was plug and play very easily. Would love to see an equivalent IP6 version somehow. I am using mine outside under the gazebo for backyard audio. More than enough power to enjoy the music. Sound quality (based on my bluetooth connection) was really good.

Review: Genau die Funktionen, die wir gesucht haben:- bluetooth Kopplung für Musik aus allen streaming Diensten über Handy, Tablet und Computer- cinch stereo Eingang für Plattenspieleroder Ton aus dem HDMI Splitter zum Filme gucken. (Bild und Ton sauber synchron)- genialer sound aus unseren HiFi Passivboxen.Die Alternative wäre ein teurer AV Receiver mit komplexer Bedienung gewesen.Hier haben wir klein, stark und einfach zu bedienen ein preiswertes Gerät mit echt starkem Sound gefunden.Verzerrungsfreie Wiedergabe auch mit sehr hoher Lautstärke aus unseren Canton Boxen.Danke für dieses Gerät!

Review: Je suis très impressionné par la qualité de ce produit. L'ampli ne produit quasiment pas de souffle. Il ne chauffe pas (c'est la magie de la technologie "classe D"). Il est petit, compact, facile à brancher, simple et très bien conçu. Largement meilleur que nos amplis d'autrefois (de "classe AB") dits "HiFi", qu'on aura pu acheter dans les années 1970 à 2000. Le prix est très modeste. Rapport qualité/prix exceptionnel.
