Topping MX3 Built-in Bluetooth Receiver DAC Headphome Amp Digital Amplifier (Black)

I really like the product. I use it to power my Klipsch kg 2.5 in the bedroom for music. Bluetooth functions well within the room. Though, its remote sometimes kind of not functions well. I'm quite not sure if I got a defective product or it is just the way it is, but there are several times wherein I try to push the next button but the MX3 doesn't respond. But all in all, it's a great product.UPDATE: Deducted 1 star on my review since the USB input has suddenly stopped working. Whenever I turn to USB input it has no sound at all. Though everything else is still working, it's just sad that the USB input suddenly malfunctioned.UPDATE2: All functions working well again. maybe it was just a bad usb connection. Tried the usb connection using other laptop, and it works. Great item

This is a high quality and very affordable amplifier that can input and output sound in various ways. In my office I have it plugged in by USB to my Windows 10 PC, then my Bose consumer PC speakers are plugged into the Topping DAC. It's a world of difference; the soundstage and imaging are greatly improved even with the inexpensive desktop PC speakers. Comes with a plastic remote control that works well, but can be fiddly about aiming even when close by the DAC.Very happy with the build quality of the DAC itself. Nice value. Excellent display too.

Update: Still working great after 3 years. I did find one other issue but it has a simple fix. The volume control from the knob becomes erratic over time, skipping randomly up and down as the knob is turned. But a system reset provided a fix for me. Turn off unit and turn volume knob counter clockwise 3 times. Every few weeks or months, just need to reset and volume knob behaves again.This thing does lots very well. It's amp and DAC are really great. It is solidly built and a pleasure to use.Pros: Amp is powerful enough to drive my bookshelf speakers with authority. The headphone out is a strong signal. Sound is clean with very low noise and distortion. DAC seems to do well with a variety of sampling rates. I listen mostly to 44.1 Mkz 320 kbps MP3's. They sound great. But I've tried some higher rate material and it does sound impressive.Cons: Sub out keeps playing even if you switch to headphones. Worse, my sub gives a loud pop when I turn off the mx3 while the sub is still on. My work around is to use the speaker level out for both the sub (which thankfully has speaker level in) and my speakers. This sounds great and no issues with sub pop or staying on when I switch to headphones. Also, many of the controls are remote only. This is annoying for a desktop arrangement. And the included remote is very lightweight plastic. I am worried it will not hold up for years. The headphone jack, works fine, but does not seem to be same quality level as the rest of the build. I'm also worried about the headphone jack wearing out over time. Work around is I just leave headphones plugged in all the time.For my application, the flaws are minor and overall I am very pleased.

Overall I'm giving it a 3. However I still recommend the unit if you want a very flexible DAC AMP at a low cost. Without the issues mentioned below I would have easily given this a 4 or 5 star review....Pros:* Lowest cost for features* Many input options* Drives headphones and speakers, both with adequate power to use high quality unpowered speakers and fairly high resistance headphones.* Very good DAC sound *compared to similarly priced products*. You'll spend 2x to get a better sounding DAC with fewer features.NOTE: if you're going for a DAC that is noticably better than modern (2017+) high end PC motherboard solutions you'll want to pay extra. This unit sounds approximately equal to the ESS Sabre 9118 DAC on my motherboard (naturally DAC sound quality is somewhat subjective, so YMMV).* Great form factor and solid build....Cons (at least on my unit after a few weeks)* I purchased from Amazon and it shipped to me in the US. However the power cord was a EU style cable. Luckily it was a standard 2 prong input to the power brick and a cable from an old Thinkpad worked. I emailed Amazon to make sure this was not a problem and was directed to contact Topping. To be honest I feel Amazon shipping a EU cable version to the US is an Amazon problem. But I'm just not going to pursue this. NOTE: the EU cable has an inline fuse. This *may* be a part of the following issue?* When using speakers my unit will reset itself when volume is set above <> 92 (out of a Max of 100 ... 92 for loud music, 95-96 for quiet speech). This reset will have the unit cycle power and the come back on at the previous volume which means it will keep resetting unless you mute audio or quickly get the volume lowered in the time between the unit rebooting and the amp kicking in. So far this has not cause damage but I won't ever crank above 90 again. This was done using optical input and outputting to Micca RB42 speakers (highly recommended). This is why I 2-starred Volume control. Aside from this issue it is excellent. I'm curious whether not using a power cable with fuse to the power brick (see previous "Con") is affecting this?* USB audio does not work as output for me on Windows 10 64bit Pro build 1903 (fresh install). I see the device but driver does not seem to load. I haven't yet tested Linux. If it works Linux I'll be fine using optical for Windows and passing USB through to the Linux VM. I'll edit this once I check that if I don't return it.* Virtually all Topping support information is in Chinese only. I was unable to figure out if there were firmware updates or Windows USB drivers from Topping. While not surprising, and there may be nothing to be found in the first place, English support would have been nice. EDIT: turns out the MX3 has no firmware update capability. This is probably going to convince me to return it given other issues noted.* Bluetooth does not support APTX nor LDAC. APTX would have been nice. I use it mostly for my phone when I'm doing frequent PC reboots and so this isn't a huge issue for me but will be a deal breaker for many.* I don't use a subwoofer, but if you do be aware that there is no crossover. Speakers and sub will both be full range. And sub is reported to not work if headphones are plugged in even if you set mode to speaker output....That's a lot of negatives. However if you get one with the correct power cable, and just want a small decent DAC AMP to handle multiple digital inputs with good speaker output and reliable headphone auto-switching mode ... I would still give it a tentative recommendation especially given recent price drops. Just be aware of the details and issues to make your decision.

I love it, this thing slays a sound bar. The only thing I'm not a fan of is the remote battery. It sometimes comes loose and the remote doesn't work unless the battery is reseated.The sound quality is great and it works great for my desk and TV.

This AMP is all I need on my desk. Powering 2 passive speakers and my headphones.Able to switch between usb, opt, bluetooth makes this an allround winner for me.Only complain I have is that it would have been nice if the headphone port could output a bit more power.

Es un todo en uno inmejorable. Me ancanta la combinación que hace con un par de bocinas Micca MB42 que tengo. Suenana muy bien.

Lo primero es que pensaba que iba a tener que esperar como mínimo 3 semanas para que me lo trajeran de China, y ha llegado en menos de dos semanas.Tiene todo tipo de entradas de sonido: RCA, bluetooth, coaxial, usb, óptica. Tiene potencia de sobra para mover unos altavoces de estantería, tiene toma de auriculares, tiene ecualización de graves y agudos. Tiene todo lo que puedes esperar de un amplificador tradicional, pero en un formato ultra compacto que podrás colocar en cualquier sitio. Hay muchos amplis chinos de clase D, y muy baratos, pero este es el más económico que incluye tantas cosas.En cuanto a la calidad de sonido, según mi criterio de no experto, da un sonido limpio y nítido. No noto una gran diferencia con respecto a la minicadena que usaba antes con estos altavoces, quizás los agudos un pelín más "sucios" y las voces un pelín más opacas en el Topping, pero es una diferencia muy leve y todavía no he tenido tiempo de hacer una comparativa rigurosa y objetiva. He visto vídeos de audiófilos que están encantados con la calidad de sonido de este aparato, pero bueno, sigue habiendo algo de polémica porque estos aplificadores digitales usan una tecnología diferente para general el sonido. Quizás un experto de verdad pueda notar deficiencias de calidad, y analizando las ondas de sonido en un osciloscopio podrás incluso ver que no es lo mismo que un ampli normal, pero te aseguro que para el uso del día a día de la mayoría de los mortales, la calidad que da el Topping es mucho más que suficiente y satisfactoria.Tiene una pantalla estupenda que siempre te muestra el volumen actual (de 0 a 100 o en dBs) y la entrada de sonido seleccionada. Se ve un aparato bien hecho, la ruleta principal da sensación de calidad y responde de forma suave y precisa.En cuanto a cosas negativas, para mí, lo peor es que hay funciones, como el ajuste de graves y agudos y alguna otra cosa para las que dependes del mando a distancia. No hay manera de cambiar esos ajustes con los controles del propio aparato. Eso me parece que está bastante mal pensado, pero si eres mínimamente cuidadoso y no pierdes las cosas, no debería ser un problema. Esto lo sabía antes de comprarlo, así que, en cualquier caso, por el momento estoy muy satisfecho con mi compra

Weil ich auf der Suche nach einer kompakten Verstärker/DAC Kombination war bin ich auf den Topping MX-3 gestoßen. Hat mir optisch zur Konkurrenz am besten gefallen, also bestellt und gewartet.Die Lieferung nimmt etwas Zeit in Anspruch bzw. der Zoll in Österreich ist alles andere als flott in der Bearbeitung.Nachdem ich den MX3 nun mit meinen KEF-Q150 und Meze Audio 99 Noir ausprobiert muss ich wirklich sagen, dass ich begeistert bin. Wirklich kompakt, findet am Schreibtisch Platz, einfache Bedienung, Fernbedienung finde ich auch in Ordnung und definitiv genug Leistung für den Tischbetrieb.Die KEF-Q150 genehmigen sich zwischen 10 und 100 Watt, bei Zimmerlautstärke ist der Drehregler gerade mal bei 20/100.Sofern man also etwas Geduld zwecks Lieferzeit hat, kann ich den MX-3 uneingeschränkt empfehlen.

Superb unit. Fantastic build and functionality. The LED read out looks very smart and is dimmable. Gives sample rate of incoming signal if connected via digital ins. It sounds far more powerful than seems possible despite it's small rating. Controlled with punch and very good micro dynamics. It makes music sound alive.Criticisms? It is almost wrong to even bring this up considering its ridiculously low price but upper mids can on occasions have a very mild 'class D' shine. I am saying very mild as it never really intrudes. However, this can easily be re rectifed to taste as the tone controls which work in the digital domain are very good with a wide range of adjustability.Add a remote and bluetooth (which I dont use, I connect via a Chromecast Audio and ESS Sabre outboard DAC for superior quality) and this little unit makes a whole lot of sense for Audiophiles that are fed up with large, dust collecting boxes or stupid price tags. This looks good in a smart town apartment or cottage.EDIT; I have now added a valve buffer stage (separate review) and it has further elevated this amplifier. So much so that I would like to take this to an audio show, put it next to a multi thousand pound system and see the faces of visitors.The valve stage added weight, smoothness, sweetness and separation which is comparable to my Hegel H90 which is not good because that cost me over ten times as much as the the above two units together.Highly recommended
