Hola Amabrok. There are a little tricks to make them to sing better. The quality of the audio gear components and also the cables. Expensive gear not necessary means good sound. You have to match the electronics to your needs and taste. Here, you will find a lot of members who have the Montis, and use a lot of different stuff, and they are getting wonderful results. As an example, to my ears, ML loves silver for speaker cable and Interconnects. Many of us, use tube gear, but you will find that certain brands of SS are specially designed to drive the difficult load of the stat panel. Remember that the panes behavior is like a big capacitor, not an inductor, as the cone speaker is. To drive the stat panel, must be a very stable design. Usually three types of technologies are available: Tubes, SS and Class D.
Speaker placement is very important. Also, the tilt and rake angle where you are seated. Your Montis are very easy to adjust the bass energy to your seat. Remember the general rule: Where you liked, bring the knob at -2dB less and that's the position. Happy listening!
