M3X

This is a current-boosted version of the M-3 Monoblock Power Amplifier

Premium Silver/Premium Black.

It doubles the current supply capacity without compromising the spatial expression and penetration power that are characteristic of single-push amplifiers, successfully achieving both delicate expression and overwhelming driving power.

Newly Developed Transistor Pairing Method:

We've developed a new, precise pairing method that even aligns the hfe (current gain) fluctuation rate, which changes over time due to changes in transistor current during music playback. We input hfe measurement data for numerous transistors at various current values, calculate the Euclidean distance for all combinations, and select transistor pairs that fall within a reference value (a level that can be considered identical when measurement error is taken into account). This method achieves a "smooth parallel push-pull" that rivals single push-pull. The output stage employs a pair of industrial TO3 (metal can type) transistors, the same as used in the M-3. To easily drive the two TO3 transistors, a TO3P transistor is also used in the driver stage, resulting in a total of four-stage Darlington configuration.

Copper Plate Heatsink Doubles as Busbar

The main heatsink is a lightweight, compact copper plate heatsink, something unheard of in conventional high-output amplifiers. This heatsink also serves as the power busbar for the can-type transistors, whose terminals penetrate the busbar and are mounted directly to the PCB directly below. This eliminates the wiring that is a drawback of can-type transistors, eliminating instability caused by inductance components while also eliminating the degradation in sound quality that can be caused by damping the device with an insulating sheet. Furthermore, the heatsink's physical isolation from the chassis provides a sense of freedom and clarity, providing a tremendous effect on sound quality. This truly kills three birds with one stone. Furthermore, the elimination of the insulating sheet in the M-3X improves the thermal coupling of the transistors, eliminating the time axis bleeding caused by temperature differences.

The voltage amplification stage employs a non-feedback differential circuit (new Type-R circuit) redesigned specifically for power amplifiers. The gainless differential circuit, emitter follower, and full-swing voltage amplification are achieved by a single transistor. This transistor's load resistor is connected only to GND, creating a "single-stage, single-ended, non-feedback circuit to GND." This new Type-R circuit, consisting of only four bipolar transistors and ten resistors, is essentially the same as a vacuum tube single-ended amplifier, but delivers wideband, full-swing output in a more streamlined manner. It's an ideal non-feedback circuit, worthy of being called a reference.

Ultra-simple configuration

The M-3 was born from the discovery that a power amplifier handling large currents should be dedicated to a single function. It has only one set of input and speaker terminals. It is a single-function monoblock power amplifier, lacking not only a selector or attenuator, but also any other switching functions. The signal input from the XLR terminal is connected directly to the base of the first-stage transistor, amplified in a single stage, and output via a single push-pull. The only operation required is the power switch. Of course, there are no unnecessary circuits or components, such as a microcontroller

.

Ultra-low copper loss 1600VA non-impregnated toroidal power transformer

We have developed the largest power transformer allowed under the condition that it can be carried by one person.The huge power transformer is mounted vertically on the front panel so that the direction of leakage flux is parallel to the board, and is suspended by a titanium washer to prevent harmful vibrations from being transmitted to the chassis, and is grounded with a single spike directly below it.

The high-speed non-feedback power supply

rectifier capacitor uses a specially selected, high-voltage, small-capacity, low-magnification foil filter capacitor with a capacity of just 470uF. By optimizing the capacitance through the number of capacitors used and reducing the load on the power transformer, the effective regulation of the ultra-powerful power transformer is further improved. The rectifier diode also uses a new, latest-spec SiC diode with an increased allowable inrush current value. This is the most powerful and high-speed power supply configuration imaginable.

The amplifier container is completely separate from the main housing and supports itself with three spikes.

The M-3X has a total of six spikes: three on the main housing and three on the amplifier container. Even though the two housings are completely physically separated, the power supply line from the power transformer is kept as short as possible, eliminating the effects of transformer vibration and leakage. The overwhelming effect on sound quality achieved by this ideal construction can be experienced by removing and attaching the shipping screws. Of course, the top panel, AC adapter, speaker terminals, input terminals, and bottom panel are all left unattached for the sake of sound quality.

I don't know how I ever lived without it.
I'm very happy with this device. My laptop doesn't have an ethernet port and only has one USB-C SuperSpeed port, so I bought an ethernet to USB-C cable to connect my ethernet switch to the Anker and into my laptop's USB-C port, and it works great. I don't need a fast internet connection for the things I do, so my service is only a 50mbps symmetrical up/down connection, and that's what I get even while transferring files from my external between other devices, charging my phone, and using composite devices. I bought the Anker 100W Compact and Foldable USB C Charger for it and it charges my S24 extremely fast. It's very well built, yet super lightweight. I love the sleek, slender design. It's the perfect size to easily slide into a pocket, store in a desk drawer, or keep handy in a laptop case or backpack. Using it is easy. Just plug it into your computer and plug your devices into it. Just make sure you have a power supply for it if you're charging or powering other devices, using external storage, or running anything else that taxes USB power. I have had ZERO connectivity issues with it — no random disconnect/reconnect blips, no failed transfers for huge amounts of data that have taken up to 45 minutes, no static his or crackle when my headset is running through it... no problems at all. It's actually kind of spooky now that I think about it... I can't recall a time I've ever had a similar device that didn't have some nuance that got under my skin, like a loose connection, random disconnections, having to reinstall the drivers all the time, or having to troubleshoot just to get it connected for the first time. The most stress I've put it through was with my keyboard connected, ethernet running through it, my S24 charging and transferring about ~20gb of pictures and videos to my 2T external HD at the same time that my laptop was transferring about ~500gb of media and documents to the HD, too, and I was surprised by how warm it DIDN'T get. My only complaint is trivial and unique to my situation — I wish output cord was longer. About six inches would do. My laptop sits up on an adjustable stand that clamps to my desk, and the end where the output cord is hangs a few inches off of my desk. This puts extra stress on the USB-C port and can wear it out faster or damage it. I haven't had a use for the HDMI port yet, but I eventually will. I use all of the other ports for my work and personal devices, though. These include: a 2tb external hard drive; a Poly Blackwire 3320 Series headset; a dongle for a wireless mouse/keyboard combo or a wired keyboard and a dongle for a wireless mouse; my Galaxy S24 charges and transfers files through it super fast; I have several thumb drives ranging from 20gb to 512gb that I regularly use; I recently bought an RCA/S Video-to-USB converter to digitize old home movies I plug into it, too.

Anker wins again.
Worked well for usb hub but hdmi was not reliable. Disappointed because usually Anker products are good quality. UPDATE: Anker voluntarily offered a refund so my faith in Anker has been fully restored.

Perfect with a MacBook
The Anker USB C Hub works great with my MacBook Air. I paired it with the Anker 100W MacBook charger which plugs directly into the USB C Hub so I only have to plug in one cable like a true docking station. My Apple MagSafe charger stays in my briefcase so I always have a charger when I'm away from my desk. I also plug in my external monitor and an external hard drive. I highly recommend this product!

3 YEARS LATER REVIEW, and 2 YEARS LATER REVIEW
Style: 7 in 1 【1 HDMI】
(3 years now I have had this and today is July 12th 2025. I literally love this thing so much I came back yet again to tell you after 3 years it works just as good as the day I originally got it. It is scuffed and scratched, has the remnants of tape and stickers i applied over the years, it has seen much wear, tear, and abuse by me, and works perfectly! ANKER makes great products, but especially nowadays when there is so much cheap garbage out there, everything i have brought by ANKER just works everytime. The only time I have had an issue? Is when I broke something, or dropped it under a car wheel (I actually did this with the first one I bought, not from Amazon, but a few months beforehand, it still worked until I started messing with it to see if it still functions lol), because I tend to be extremely irresponsible with my portable electronics. If you do buy this, and you forget to order a power supply, I bought a 100w power supply from Walmart for it, that is also three years old and works great as well. If it makes it 5 years, I'll be back to tell you about it. Now, keep reading to see the first review i left awhile ago) This thing is so awesome. I had to come back and write another review first off. You will need a 100 watt power supply to go with it separately just get that out-of-the-way. You can get one at Walmart for fairly cheap. That’s what I did and after about six months, I actually glued the hub permanently to the power supply so they would never be separated now let me tell you how versatile this thing is you can take your iPad plug it into the little USB-C sticking out of the end of it then you could take an HDMI cord from the hub and plug it into your TV. If you have a splitter, you can do it into several TVs or several monitors. It has a microSD card for all your pictures. It has a not as micro a little bigger memory card can’t remember what they’re called but they go in like cameras and stuff SD cards? It reads those two it’s got a USB-C out so you can charge your phone if you have an iPhone and an iPad like I do it connects your iPhone into your iPad together so you can play video games on your phone on your giant screen of your iPad running an HDMI cord to your TV now you’re playing on your phone on your monitor and your TV and your iPad all at the same time and see how awesome I’m saying this is you can plug a keyboard into it and a microphone and a mouse and now your live streaming your gaming on your iPad your monitor your TV your projector I’ve even hooked mine to a projector! I’ve literally spent hours trying to see how many items I could plug into this thing and run at the same time just so I could put it on my YouTube channel and show off and have people give me no props, shake their heads, and say I’ve got way too much free time on my hands. Doesn’t that sound amazing? That could be you. One guy who made fun of me relentlessly in the comment section a week later asked me where I could get one and guess what I told him I could get one for twice the amount that I paid for it and he paid me so I win guess what I do with the money? I bought a midi cord that I plugged into my MPC so I could play music on GarageBand on my phone. Had another cord going from the hub to a monitor where I could watch OBS for studio live streaming as a third cord projected the entire image on a wall, 6 feet across while I produce this music a microphone that I also had plugged it into the hub was recording me freestyle horribly because I cant rap, but all of those magic moments captured on a small SD card also plugged into the hub at the time I just left in the hub and when I was done, all I had to do was unplugged the USB-C from my phone into my computer and transfer all the information over i’ve plugged my GoPro into it from my GoPro. I was able to power a light and a microphone this thing is endless possibilities. Do yourself a favor and get one anchor products are amazing and guess what I’ve stepped on this thing countless times my dog thrown it across the room. It’s fallen downstairs. I dropped a puddle of water put it in a bowl of rice it still works. I should be selling these things man they’re incredible.

Durable, highly functional, and super reliable
Style: 7 in 1 【1 HDMI】
4 years since purchasing this and it's still just as useful, functionality is perfect, and compatibility is high. I use this with a Linux Pixelbook most often, but it's convenient for every device I own, including Android phones and tablets. The HDMI output works really well with devices capable of video output over USB-C, and this feature has never degraded for me. I routinely loaned it to students and professors for presentations when their own HDMI dongles or SD card adapters failed and it always immediately worked. I recently ordered an Anker 555 8-in-1 hub for the addition of ethernet, but I will continue using the 341 as well.
