I have the hp for 2 years and it was at least 4 years I have been eyeing it but was very strong at launch there are more than 5 years I think (in the duty-6000f).
The top is the implementation in all places (restaurant, bar, meeting room, ...) everywhere they go and have a very pure sound that does not attack the ears even close. The least is that there is a handle to grip and it is easy to reach by manipulating pots.
I've used other brands in this range as mackie but it was in a gymnastics pa and they are suitable for this type of place is no comparison.
The value for money is good.
For the choice I ferrai the same again.
