I use it for almost a year and my opinion is mixed. First I did not know it was mono, and I do not understand why since there are 2 columns each with an amplifier. I useful formula "piano bar" with a synth workstation. Most of the sounds in stereo sound not at all. The solution for the stereo is obviously to take two, but then the price would become prohibitive to me from a very good sound "classic" and very cumbersome for small spaces. Moreover, contrary to comments I have read, I have a lot of feedback! Otherwise, the sound is good but not super utilioser latofs. I also think to sell ... or buy a second for stereo.
Ah! I was forgotten HUGE bumps in the low to the point that I could not make use of C #! not easy to translate to VIEW! lol. The addition of an equalizer seems to me indispensable! This obviously complicates the convenience of the product!
