HPA 1 : Excellent high quality amp which I can't live without

I've had this a few months now and it works perfectly and has transformed my rock singing and is saving my ears - no more ringing and I'm better in tune. It's really hard to fault and I won't sing now without it. The amplifier is very low noise and has excellent sound quality. It can go plenty loud enough for any occasion without getting harsh. The limiter is useful preventing drums and other noises in the mic from being unpleasant. I've seen it operating quite a lot. The box is quite big for this type of thing but is very strong and has a nice durable finish. The size isn't a problem if you wear it behind you as most people do. There is a feature where you can mix left and right into mono and adjust the mix while you are wearing it. Although this works well having a mic cable and 2 more XLR leads attached to you is a step too far unless you are very still. I use a mix from the desk and once it's set it's generally close enough for the whole gig. If you are thinking about in-ear monitoring this is a good way. To get this quality with wireless would be many times the cost. It's very important to use some good ergonomic noise isolating headphones though, something like Shure SE215.
