Blackstar HT-5 or HT-1?

I'm looking at buying an all tube amp. I play metal, mostly pantera, slayer, metallica, megadeth and sepultura type stuff. I live at home so I don't want to disturb anyone, so it needs to be able to get good metal tones at low bedroom volumes. If there are any other amps that meet the criteria don't hesitate to tell me.
