need help with gear purchase

[davormen]

Ok, if any of you have any experience with the following, please chime in:

Wharfedale Diamond Monitor 8.2A
ADAM ANF-10 passive monitor
Celestion G12-65 speakers (in a 1960-style Marshall B cab)
Mesa/Boogie Studio Preamp

Not the most common items, but that's why I need your help... any of these worth it (for metal obviously)?

:Spin:

Adam monitors are nice, but I have no experience with the ones you mentioned.

The studio preamp is good, very close to the Mark IIC+, awesome for rhythm.
