I'm going through that very thing right now. I'm using a Mapletree 4A SE tubed pre. It's a two chassis pre. It can use either 12SN7 or 6SN7 tubes(switch on back)and is tube rectified. The sound is much more relaxed and the soundstage is wider and ...

I'm using a pair of (dual subs) Signal Cable Analog IIs with Eichmann Bullet plugs.

How hot should a McCormack DNA-225 get?
I had a similar problem with a DNA-1 tripping a new 20 amp breaker. Some one suggested this http://ecatalog.squared.com/fulldetail.cfm?partnumber=QO120HM and it solved the problem. It's a 20 amp breaker designed to allow a larger inrush of power. ... 
my tubes are hissing non - stop
Try replacing the tubes in the pre. Sounds like the place to start.
