Initiative: What stacks where?, Questions about the different rulesets interactions of magic and ware. Options

[UnLimiTeD]

So, uhm, hi.
I was hinted at this forum having a few grumpy old men people with good rules knowledge, so I figured "can't hurt to ask".

So, to the meat:
I recently, while mulling over a character concept (even before I fired up the excel), stumbled upon this bit:

Reaction enhancers ... are incompatible with all other enhancements to Reaction, including wired reflexes.

Wired reflexes are incompatible with augmentations that affect Reaction or Initiative.

However, when I discussed the implications with my pool group, it turns out that in the german rulebook, it reads the (freely translated) the equivalent of:

"Reaction enhancers are incompatible with augmentations that increases reaction"
&
"Wired reflexes are incompatible with any form of Reaction or Initiative Enhancement."

Now, I can't expect anyone here to know why, but as to the implications:
Am I right in my assumption that in the english version, Reaction Enhancers + Wired Reflexes would be compatible with Adrenaline Boost and/or Vampiric speed?
And would, in the german version, Reaction Enhances stack with the Improved Reflexes Adept Power?
Are there any other options to 'get cheesy'?
