How does it compare to your Dual Thel NT-25HQ-09 LPS?

I wish I had a soundcheck guest who hears a difference here. I do not hear it.

User difference: Here no need to adjust the voltage.
For me Thel is traditional and OSA the more modern way.

Thanks judydudi.

Maybe I will consider this one for my project ;)
It is a bit in between the NT-25 and the NT-50. Not as big as the NT-50 but not as strong, too. choices, choices :lol:
