I have a Schiit Magni Heretic. Dressed in black (with red but not garish-red side panels), it does its job without fuss. It also feels well made for the modest price. I do not know if your Verums are hard to drive, but the Heretic has plenty of power for the phones I've tried, even in low-gain mode.I'm looking for a new headphone amp, my only requirement is that it has a 3.5mm or RCA input, any other features are a bonus, but not necessary. Preferably, the closer it is to a black or dark grey metal box, the better. Clean power, and clean sound is all I'm after in an amp, I'll let my headphones color it afterwards.
