Switchable Tetrode - Triode please explain


I am using a VTL ST-150 which is switchable from 175 watts tetrode to 80 watts triode . Can anyone please explain the pluses and minuses of these two modes ? Thanks!

The System I am using ...
CJ Premier 14
Linn Lp-12 with lingo , Grado
Sonic frontiers SFCD1
Aerial 10T 's

I listen to Pop rock , Jazz , Blues and Classic rock. I like to play mostly at concert levels !
I think the Tetrode mode produces more forceful bass and is a little more lively. Powering down as per VTL does make it more difficult to compare. I like the VTL amp very much! I just think the explaination of this issue on the VTL web site is weak.
