You either have some mis-typing or have got confused. Your "have heard" bit comes from Studio Reviews via Recording Hacks, where the M16 is clearly listed as "over $1000", and actually had a list price of $1395. Telefunken USA introduced this as a selected version of the same mic that Apex sells as the 460. The M16 has since been replaced by the M16 Mk II, which is a serious middle-range microphone.
As for the pre-amp working with your Edirol interface, you will have to give us more details of exactly which models of each you have, and how you connected them to do the supposed damage. If you took the pre-amp outputs into the TRS line inputs of the Edirol, then the state of the XLR phantom power on the interface would have made no difference to the Edirol.
