* How long have you use it? They were used primarily for sound with a large hall, in place of a PA2600 Boost * Have you tried many other models before buying it? Apart from Boost PA2200 PA2600 Rope B 130W, Power of a 22kg 2x250WRMS not. * How long have you use it? They have served as two times: both say they are nearly new. * What is so special that you like most and least? Most: power, I like serrated knobs. The least: too sensitive perhaps? are what really less? * How would you rate the quality / price? Excellent. For the 8 ohms love this amp, it behaves very well: I have not taken any risks. I symmetric supplies have no worries (box samson symmetrization). * With experience, you do again this choice? ... For use as a dilettante like mine, yes may be the EP1500 to 31cm. Oh one last point: in 4x450WRMS/20-20Khz EP2500 2: sound of a large room with a correct pressure. I was filtering on-12db 30Hz in équalo. So it grows, if you have good speakers so it grows stronger there's no problems. PS: do not compare with Dynacord in 2X600W good but it is rather nice for the price.

Last point: the best are cold, especially when empty.
But I had calculated the margin for the SM115.
