I recently took a huge step up form my current Xonar essence ST and Sony CD900STs, and bought a Mytek Stereo192-DSD DAC, a Violectric HPA V181, and a pair of Mr speakers Alpha dogs.
 
None of them have arrived, but I will probably be waiting another 5 weeks on the alpha dogs, and will be using my CD900STs with the other 2 instead
 
Would setting the pre gain on the V181, to anything over the -12db, setting damage sensitive, low impedance cans? Should I have bought a less powerful amp? Are my fears unfounded?

You wont have any problems, the 181 is a great and versatile amp
Pre gain settings just give you more range on the volume control
For example a sensitive pair of cans may become too loud at around 10 o'clock on the higher setting,
switch to a lower setting and like magic they will now become too loud at around 1 o'clock giving a larger range on the knob to play with
