I used to own Power 3s and if "warm" is the sound you're looking for, I'd suggest demoing some other amps. I didn't find the Power 3s a very good buy. The Power 2 is a much better buy, you can get a new one in the $2500 range.
A good, warm soundinng tube amp (in my opinion) is the ARC VT100 MkII or III. A Mk II can be had for $2300-2500 used.
Good luck.
