I've not known the Monarchy to be edgy in it's digital presentation. I had the M-24 which was only tube output stage that I used with a Northstar transport. In this price range a transport can make a difference. CC Poon at Monarchy sometimes recommends a jitter device between the transport and DAC, like his Monarchy DIP or a Genesis Digital Lens. Maybe that's worth a try, they're pretty cheap used. Otherwise maybe speaker positioning.
What's your room like. Room treatments could help if you're not using any. The people who suggested power conditioning may be on to something as well. RFI/EMI can add that edginess to the sound you are describing.
