Well, being in the business of hearing healthcare, I'm to some degree all in favor of people blasting their eardrums at unsafe decibel levels for extended periods of time, because that kid who sits and noodles in front of a crank 4x12 ensures job security lol. People are certainly free to listen/play music at whatever volume they want, just as they are free to shoot guns without hearing protection, use chainsaws, smoke cigarettes, eat red meat etc. Plenty of information about there about what is and isn't safe, and we can all choose which things we think are worth paying attention to and which aren't. I certainly do plenty of things that aren't in the best interest of my health, but I also do try to do other things that I think make good sense....
In a more practical nature, I think the question of if ones "bedroom" is in an apartment complex or their own home makes a huge difference in the debate. If you've got people on the sides and above/below you, or likely going to be pretty limited in how loud you can play before having complaints. I remember back when I'd get people banging on the ceiling when I was just trying to get even my 5 watt amp at a modest volume. Shared living can be a real PITA
On the other hand, if one lives in a home out in the country, you can probably crank a 100 watt head and no one will likely be around to complain, unless of course you've got a wife, kids etc at home, which again from experience can be a real limiting factor. I've have high wattage amps and large cabs and while I can crank it without neighbor complaints, the misses certainly raises all hell when stuff starts vibrating off the shelves....
The OP's needs are for "just jamming at home"
I would question is he/she happy with the KRK's ?? Is this just an issue of "the internet" making someone believe they "need" active monitors or a tube amp/cabinet setup just because "other people" on the internet, likely with very different needs, use that ?
Its liking thinking you need an R8 just because a lot of guys on a site like TGP have one...
I do have a pair of CLR's, but I also have some 6" Sceptre coaxial active desktop monitors. Both sound fantastic at equal volumes, with the desktop monitors giving me the best imaging. The CLR's are reserved more for times when I take them out of the house and can get far louder. The desktop monitors though can easily get to a volume level where I would not want it any higher for home use.
If anything, they work a bit better for dialing in some patches though, as the CLR's, at least when they are in my smaller office/music room, really tend to have too much bass. Its an untreated room after all, and while I can get an awesome kick in the chest thumb with each palm mute, the sound doesn't translate that well to playback on other systems.
Its not the fault of the CLR's, its an untreated room issue. Best way to combat that is to listen with near or midfield monitors, which give be a bit more representative idea of my tones because I'm hearing things more direct.
Luckily for the OP, he/she has some easy options, such as buying an ASM-12, or DRX10 etc from a place like MF or Sweetwater, which will gladly let you return it if your not happy. Likewise Atomic gives you 15 days to return as well
So, give it a try. Don't sell your KRK's yet, or likely keep them for mixing etc, and see if your happy with something like a high power active wedge for home use. If it makes you happier, if your neighbors don't complain etc, keep it and be happy.
I certainly like having the option to use the CLR's, and sometimes drag them out into the family room when everyone is gone and play a bit louder. I also like having nice desktop monitors always at the ready, which are great for late night etc.
Choice is good
