M-Audio Forty Sixty

I got these to replace a pair of Eris 4.5s with the hope that the Bluetooth facility would allow me to use a wireless microphone set-up.
I've not been disappointed. The sound quality is comparable to the Presonus units, a little less analytical in the upper register but fuller in the mid range and lower. The build quality is very good and the 'app' works well on all the platforms I've installed it on (including Mac oS on my M2 Mac Mini) . My main reason for buying has been wholly fulfilled. The Bluetooth pairing is easy and my wireless microphones work with little or no latency. Happy customer!
