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.

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.

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

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.

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!

Powerful little amplifier in my opinion. I work with a lot of audio equipment and this amp has proven very useful even with its small footprint. I started by connecting it to a pair of JBL bookshelf speakers and it handled good power and the audio output was clean and undistorted. I then played around with balanced and unbalanced inputs coming straight off my DSP and the sound quality was very good on either input. I connected stereo speaker outputs and the amp handled individual speakers at 8 ohms with 100 watts clean power delivered to each speaker. I then series in a couple more speakers which brought my impedance down to 4 ohms and the rated 200 watts in 4 ohm mode was clean and powerful. I then tried the bridging feature which gives a full 400 watts of power at 8 ohms and used my DSP to crossover at 50Hz which delivered nice clean bass audio to a 12” ported subwoofer. I’ve left the amplifier connected to my subwoofer and it currently resides in the corner of my office with great acoustics and lets me play study focus music during my workday. I can’t get over the audio quality from such a small amplifier but it’s a fully rated class D amplifier which explains the efficiency factor and performance. The inputs are a plus as I like the onboard XLR connectors for a balanced input straight off my DSP which have balanced connectors already so no conversion is required. The fact that unbalanced RCA are also available make this amp versatile in several applications. The banana plug outputs are also very nice allowing you to secure bare wire or banana plug terminations.

This amplifier was pretty simple to get connected and definitely made a difference in sound quality when hooked up to some fairly average speakers. I'm definitely not overly technical, and even I was able to get it going pretty quickly. It's pretty straightforward and doesn't have a lot of buttons that I likely would not know what to do with. I just wanted my speakers to sound better, and they do. I do wish it had a remote, but other than that, I thought the price was good, so overall, I am very pleased with it.

This is heavy and built like a tank. Beefy to the extreme. It also has a ton of power. I barely turned up the nob, just a tiny bit, for both my Fisher XP-75A speakers and my Cambridge Soundworks Model 6 speakers and they were already and listening volume. Just a ton of headroom. I cannot imagine why you would need to bridge these in Monoblock mode, but you can. The Balanced inputs are a nice touch. You will need a preamp of sorts or a source selector to use this in a traditional HiFi since you only have one set of RCA inputs and one set of balanced inputs. If you only plan to use a DAC with this, you are golden. For the price, you can find other offerings with more features, but this certainly has POWER.
