Can you put a Krell in an apartment?

In an apartment I'd run a smaller amp with better power conditioning.

Looking at the spec, it draws 350 at idle, 3,000 max.
The 350 is do-able in an apartment, but it will be a room heater. The maximum power draw at 15 A (the usual, non dedicated circuit)  is usually given to be 1,800 W.

You could probably get away with it, but I'd still recommend power conditioning that can handle 15 or 20 Amps, mostly due to how dirty apartment power can be.

Keep in mind, apartments = small listening area. You don't need as much power, and smaller speakers tend to do better. Treat your room as much as you can, and you'll be amazed at how big a sound you can get.

This is too funny...The guy is asking about an amplifier and he gets real estate recommendations...
Sorry, could not resist. 

Why do you such a powerful amp for an apartment?  It not like you will be able to play it loud. Imho, the equipment needs to match the listening room environment, unless the apartment is just an interim residence. 

In an apartment, you want speakers that sound lively and full at lower volume levels.  These types of speakers a re most likely to be high efficiency models that also don't require much power.  Even if you are already committed to some kind of low efficiency speaker, it makes sense to focus on amplifiers that deliver good sound at modest output levels.  Really big amps tend to sound a little bit lifeless when they are called upon to only deliver very low output.  I would be looking at quality, not quantity in your circumstances.

Since you are probably never going to get close to drawing 3,000 watts and you should never expect to play the amp at the limits of its capability, the bigger concern is how much the amp draws on turn on.  When the amp is first turned on, it can draw quite a bit while it is charging the capacitors in the power supply.  That short term draw may trip a breaker, particularly if there is other stuff on the line that are already drawing power.  Another practical consideration: 350 at idle is a LOT of power which is not only wasteful, it will mean a lot of heat output; is your air conditioning up to snuff in the summer?

jeffvegas - Can you still run this amp off a regular electrical outlet? If you can, will it sound like crap?

Jeff - yes and not like it can.  I would be more concerned with the detrimental long term effects the lack of power will cause your amp components - especially at start up. The power switch component will  eventually go . You will definitely see your lights dim when powering it on. A telltale sign of bad things to come.......
