Pioneer RTA ; espacially thirsty ?

Been using a pioneer for a few months now, it's a nice atty.
Iv'e noticed that it seems to use juice at a considerably faster rate than my usual Dvarw's.
Coil resistances, airflow & firing wattage being pretty much the same on either of the 2 devices – I wonder why that is ?
Anybody else experiencing similar ?
