Enhance Spell sets the spells Base Damage to the new Cap. For any Damage Dealing spell you have, that deals a number of dice of damage equal to your caster level increases by 10.
That is then the Spell Base, so if you Empower it, it will then be 30d6.
Lets say that you are correct, which I'm not sure you are. Enhance spell wins over Empower ONLY on spells of LESS than 15 dice, and then only by small amounts.
example 1:
---fireball 10d6
---enhance +10d6 (new base 20d6)
---empower +10d6
that = 30d6
triple stacked empower = 10d6 x 2.5 = 25d6
30d6 vs 25d6
empower loses
example 2:
---cone of cold 15d6
---enhanced +10d6 (new base 25d6)
---empower +12.5d6
that = 37.5d6
triple stacked empower = 15d6 x 2.5 = 37.5d6
37.5d6 vs 37.5d6
empower ties
example 3:
---chain lightning 20d6
---enhanced +10d6 (new base 30d6)
---empower +15d6
that = 45d6
triple stacked empower = 20d6 x 2.5 = 50d6
45d6 vs 50d6
empower wins
example 4:
---horrid wilting 25d8
---enhanced +10d8 (new base 35d8)
---empower +17.5d8
that = 52.5d8
triple stacked empower = 25d8 x 2.5 = 62.5d8
52.5d8 vs 62.5d8
empower wins
Also note, for all those spells to get maximum effect of Enhance Spell feat your level must equal the dice of damage. For example, for horrid wilting you must be 35th level, whereas for triple empowering you can be as low as 25th.
I still put my money on Empower
