Sure, go for it. I have this stack. I use to run my Shure SRH840 and My grados as well.
It is quite a awesome unit, sounds great and looks awesome while doing it.
They are quiet too, i use my IEM Shure SE535 on the stack every now and again and it is not dirty.
Mind you, if i plug my external HDD on the same usb port of the stack gets a bit noisy. But only using my IEMs. Even the grados that are very extra sensitive don't get any noise.
