TX480D test by Car&Hifi : "Best Class-D amp..."

The MTX TX480D has been tested by the most competent caraudio magazine in the world, Car&Hifi from Germany. They don't have any sence of humour when it is time to test. And the result is simple and impressive : "Best class-D amp of the test"... "Medal for sound quality"... Boom...

Here are some choosen sentences :

  • "The TX480D is pretty compact and it looks noble"
  • "The PCB layout is orginal"
  • "Quality/Price : Very Good !"
  • "In contrast to other manufacturers MTX is not using chip (cheap...) amps"
  • "very big power supply"
  • "two big power transistors for each channel"
  • "The TX480D is pushing the highest power and is producing the least distortion - Chapeau MTX !"
  • "It plays very powerful and soulful"
  • "the spatial reproduction is impressive"
  • "The MTX is able to produce a realistic staging in both width and depth"

After reading the test, two words are coming to my mind : thank you and congratulation to the MTX engineers...

The TX480D is a small ultra efficient quality amp :)

Here is the complete translation :

MTX TX480D

Construction :
MTX recently introduced the TX480D, an amplifier using Class-D technology. The TX480D is pretty compact and looks noble thanks to its aluminum titanium colored heatsink. Inside the layout looks completely independent and it seems that it is not bought "off the shelf". Besides a very big power supply for a Class-D amp of this size, we find a lot of SMD parts - the MTX is really stuffed with components.
In contrast with other manufacturers, MTX is not using chip amps. Amplification ICs are not used here. Instead of that, there are two big power transistors for each channel, just used in Class-D.
Regarding the measurements the "French woman" is ahead of the field of the small digital amps in this test. It is pushing the highest power and is producing the least distortion - Chapeau MTX !

Sound :
Also regarding sound quality, the MTX is convincing. It plays very powerful and soulful at the same time. If necessary, it delivers a lot of power and very high levels. Playing female or male vocals the tonal balance and timbre is persuading. And finally the spatial reproduction is impressing. The MTX is able to produce a realistic staging in both: width and depth.


PCB appreciation (Picture on the left) :
Modern and tidy : The MTX uses an independent Class-D layout with discrete transistors instead of amplifier ICs

Results :
Sound quality : 1,2 (Exceptionnal)
Measurements: 1,3
Practise: 1,8

Rank : Upper class
Price/value : very good

"Best Class-D amp in this test"
"Medal for sound quality"
