I added a Weber Mini Mass 50 Watt attenuator to my DT25 ($80 used on ebay) and it has been one of the best investments ever.  I am finally getting the sounds I knew were there out of my dream rig (JTV- 59 POD HD500 DT25) as well as with just my Stratocaster to the DT or via the POD HD500.  With the DT Master at about 2 o'clock the great tones come right out at small room tolerable volumes.  I also added BBE Sonic Maximizer in the DT fx loop which adds to the overall sound clarity.  I recommend both but the attenuator made the biggest difference for me.  I can now actually use some of the POD provided presets which always sounded so poor to me.  If you need to play at low volumes for practice or at home this is the way to go and a better sound than the LVM.  Once you set you POD tones you only need to adjust the Volume setting on the attenuator and never have to touch the master control again if you are playing in a setting needing more volume.
