Hey all
After some bad luck with a faulty MiniDSP blowing out one of my drivers, I've decided I'm going to rebuild my active horn speakers with Fusion Amps - either a FA123 or a FA253 as it's the second time the MiniDSP has failed for some unknown reason.
I have some high sensitivity drivers - 108db, 111db and 98.5db, and with my current setup there's some very slight audible hiss from my listening position.
I wanted to know how the hiss is from the FusionAmps before I pull the plug. The SNR looks a lot better than the amps I'm currently using to drive them and I was hoping to get away without running 4 L pads for both midranges and tweeters which will keep the cabinet looking a lot better.
Any advice or feedback is greatly appreciated.

I received the Fusionamps. The ground loop is audible, worse than the Class A/Bs I'm running currently with a MiniDSP - and this is with nothing connected to the amp other than a power cord and 1 driver testing each of the 3 outputs.
What's worse is, the loud pop when the amp wakes or goes into standby mode. You get the standard click from the power supply, but it's audible (I'd say 85db+ on a 111db Radian driver) every single time it powers up or down.
Tried firmware 5.4 and 5.5 across both Hypex amps and it's no bueno on both. Modules are 2x 252MP and 100MP for the tweeter. Even setting the gain to zero across all outputs and the master, still no luck.
I can't live with that.
