- FX-Audio- L07 Stereo Audio Amplifier 200W x2 MA5332MS 2 Channel Class D Power Amp Bridgeable BTL 400W Hi-Fi Fully Balanced Amp for Passive Bookshelf Desktop Speakers Home Theater

Well exceeded my expectations! No need for op-amps (upgradable sockets with JRC4580 op-amps) or any other upgrades as it produces crystal clear sound across all spectrum and without any weakness in bass punch. Very powerful, I only use volume at 25% and it makes 97dB at 7.5ft with 6Ω Elac Debut F6.2. The amp stays cool to touch, so no overheating issues. I never knew - my speakers have bass and those dual 6.5 woofers do move. In fact, I powered off the subwoofer - plenty of bass now. It is true - there is some lack of bass in some TPA3255 based amps. FX-Audio-L07 is phenomenal class-D amplifier !!! In stock form, it will outperform stock Fosi V3 mono blocks in the sound quality and the power. After Fosi V3 mono opamps upgrade to MUSES02(purchased from Fosi to avoid conterfeit) - it edged ahead of stock L07 in the sound quality, but once L07 opamps are upgraded - it will regain the sound quality parity for sure. It lacks 12 V trigger, no auto /on/off. But it has built-in relay that properly turns on/off amp, so there is no pops when power state changes. So with inexpensive remote controlled receptacle you can turn amp on/off without any need to reach to the switch on the back.

Very bright top end and weak bass. Sound quite open. I would not buy this amplifier again. Probably OK driving bookshelf speakers. Driving yamaha 6 ohm NS777 towers with 8" bass units, the bass, compared to an FX DS07 preamp and 50 W power amp, was MIA.

This amp is amazing, the simple is the key here spend money on one thing just two inputs, one output of very clean clear warm power in a very small package

The FX-Audio- L07 Stereo Audio Amplifier is the real deal! I have a Dartzeel NHB-108 reference amplifier, so I do know what great sound can be, does this get close? The FX-Audio- L07 is a self contained stereo amplifier, no wall wort or external power brick to hide as this has an internal power supply with a standard common IEC power connection in the back, along with a rocker panel switch and an internal fuse. The power supply is also a 100V-22V so it should work anywhere in the world with the appropriate power cord. Inputs consist of a pair of balanced XLR inputs, and a pair of single-end RCA inputs. For whatever reason they've staggered the speaker terminals. The speaker terminals use better than average gold platted 5-way binding posts that are oddly staggered. It wouldn't kill them to properly color code the speaker terminals and RCA inputs. Also the fonts could be larger so it's easier to read (doesn't cost anything to increase the font size :) On the front panel is a a single input selector switch and a rotary volume knob. The amp is rated as 200W x2 Channel Class D Power Amp. It's bridgeable via a switch on the rear which is labeled BTL (why not just say mono?? vs BTL?). The amp is claimed to produce 400W in mono mode. How does it sound? I was breaking in a new pair of high quality Swan 3-way speakers using an Aiyima integrated T9 Pro amplifier, and they sounded great. That said, when I swapped in the FX-Audio- L07 amplifier, it elevated the listening experience to an entirely new level! Wow!! I thought the speakers sounded good with the little Aiyima amp, but the extra power and headroom that the FX-Audio- L07 produced was immediately noticeable not only in sheer volume, but the detail and wonderfully large sound stage that it presented are outstanding! The sound was detailed and very clean. Even with the volume at full, with the audio source paused, it's dead silent! This amp has the power to drive anything. I'm running 4ohm speakers and this amp runs them with ease, and I can crank it to high volume without distortion, it's very clean. Is it as good as the Dartzeel, of course not, but they're in a league of their own. For it's price point, it should be very competitive, as this amp has tons of clean power with both RCA and balanced XLR inputs for a reasonable price!

I got this amp to power some old-school large speakers and this thing really does a good job. The speakers they are connected to have a 12", 3" and 2" all with passive filters for each range. Performance: Hooking up wires to the RCA side and to my music player I was able to drive these speakers really hard without any distortion to the point it was shaking the house fairly well. I'm sure it could have gone more but it achieved my goal of clean and solid music delivery. This will work quite well with all my use cases from movies to general music. Controls: Not much to this one, volume and input selection between xlr and rca with a power switch. The volume control is very smooth without any detents, you can get the volume as needed without any fuss. The LED indicators are very dim which is good in my opinion, especially when using it in a darker area the indicators are just enough to know the power and state - not that those change much anyway. Power: As mentioned before it drives really well. The built-in power supply seems to handle the surges nicely and even holds power for a second at a reasonable volume when unplugged. This shows it should have a large enough of a cap inside for the surges it can expect. The only problem I have with this unit is that the idle/quiet power requirements is rather high. I was seeing a constant 9w draw on the wall and the unit gets warm in this state. It would have been nice to have a button on the front for a soft-off state or have an auto-sleep function. Otherwise I'm forced to use the rocker switch on the back of the unit.

Très bonne sonorité. Malheureusement on entend un petit bruit toutes les 80 secondes, malgré l'alimentation coupée. Cela provient de la decharge de condensateur. Pour ceux que cela ne dérangent pas ...

ich war schon einige Zeit auf der Suche nach kompakten Monoblöcken um meinen 30kg Röhrenverstärker zu ersetzen - wohlgemerkt lediglich aus Platzgründen (WAF - wife acceptance factor). weil ich durch den Röhrenboliden klanglich ziemlich verwöhnt war, konnte ich mich nur schwer mit dem Gedanken auf einen Class D Verstärker "abzusteigen" anfreunden. hab mich dann aber doch genauer mit diesem Neuland befasst, zunächst mit dem Fosi Audio V3, mochte aber das Konzept mit dem externen Netzteil nicht. bin dann zum Glück durch einen anderen Rezensenten (thx David Gunggoll) auf diesen FX-Audio- L07 aufmerksam geworden. Natürlich war ich noch skeptisch, dachte aber 1. ist es eine überschaubare Investition und 2. könnte ich es ja schlimmstenfalls retournieren. ABER: dieser kleine Kampfzwerg hat out of the box gleich so frech und munter aufgespielt (an Hornlautsprechern mit Tang Band W8-1772 Breitbändern als Treiber) dass ich kaum mehr aufhören konnte mit Probehören. inzwischen habe ich zwei davon und betreibe sie tatsächlich als Monoblöcke im Brückenbetrieb. alles supereasy, kein Rauschen, kein Brummen, nur Hörspaß mit Dynamik ohne Ende. sogar beim manchmal kritisierten Mittenbereich (Stimmen) vermisse ich nichts. ganz klare Kaufempfehlung

Very good clear sound, more believable than the SMSL AO300 with MA5332MS amplifier. RC4580 op amps are used as the best value solution, I heard a better sound with with OPA2134 jfet and then more details with OPA2228 fitted. The internal wiring is something weird, silicon wires carrying signals go very close to 240V mains. I'm not sure how that got safety approvals. Apart from some untidy soldering and the thermal solution using a squashed pad, it's the best sounding integrated PSU and amp for the money. I have a current feedback Arcam A90 power amp and Dynaudio, Spector and Dali speakers to compare with. I think it's a great little amp and only time will tell if the design proves reliable.

So far so good. It is tiny, well made and feels solid. The controls are smooth and well executed. The connectors are good quality. It has no background noise and sounds good. It has plenty of power. Provided it is reliable it is astonishing value for money. I use it home studio. 5 stars all the way.

Ein guter Allrounder. Wir haben diesen Verstärker mit Alexa gekoppelt und sind deshalb sehr froh, dass sich das Gerät nicht nach längerer Pause in den Standby-Modus schaltet, sondern immer empfangsbereit ist.
