I've got my Opals few days ago. Great sound after my old ESI nEar 05 =)
But there are 2 problems:
1) There is static noise. Even if nothing is connected. Not too loud. But long sitting in 1 meter from them without sound tires me a lot. Is that normal? Or they should be absolutely silent when nothing connected?
2) One of the speakers lost most of its low-mids yesterday. If I turn the level very very high, low-mids sometimes are there. Then I turn the level down. Low-mids are there for 5-20 seconds an then they suddenly disappear again.
I've got them new from official dealer. So I hope they will fix these problems.
BTW the pots on my one are made very rough. For example "Freq" pot on one is pointing on 220 as minimum and 70 as maximum (should be 40 and 280 respectively). Not what you expect from professional equipment.
Probably they send to Russia the worst ones. Because we have here scarcity on professional equipment and swallow everything. I don't know.
Bad luck... =(
