The M300 represents an extraordinary value. [...]. Starting recordists will want to give it a careful listen, and even fancier studios can now add a dash of the Dane as a second reverb or backup delay for very little outlay. Thumbs way up.

The bottom line is that this is an extremely competent, well-designed machine, packing a lot of professional features, I/O flexibility, and excellent sound quality into a really compact, easy-to-use, effects processor. […]. Highly recommended.

... it sounded just as I was hoping it would - at any level, both effects engines as well as the 24 bit converters. I am sure TC will sell a lot of these processors. This little box is a real piece of jewelry thanks to a manufacturer who knows how to take advantage of its huge number of first-class technologies and algorithms [transl. red.].

TC have taken a leaf out of Lexicon's book and released a budget unit not only worthy of their name but that is generally easy to use and has some great effects in it. […]. In summary, the worst thing I can find to say about it is that I had to give it back at the end of writing this review. So I'll be buying two!

The price/performance ratio has never been brought to this level before, and the ease of use does not get any better. […]. All of the effects and reverb algorithms are top notch, and a lot of studio professionals are really going to be mad that they laid down the kilo-bucks to their effects when now the same quality of sound is going to be doing roadwork at a local gigger venue near you.

"El M300, es un procesador multiefectos de multiples aplicaciones y que ofrece la calidad de un lider indiscutible [...]. En el mercado de procesadores de bajo/medio precio, el M300 tiene pocos competidores, es un procesador de calidad, avalado por TC Electronic y de una gran fiabilidad, con este modelo la empresa danesa ya cuenta con procesadores en todas las gamas del mercado, y eso es un aliciente desde luego."
