[Elecraft] Microphone capsule for K2

[Karsten Eppert (DK4AS)]

I have purchased together with my K2 an MH2 microphone short before it 
was discontinued two years ago.
The reports I receive always state, that the mike has too much bass.
The filters of my K2 were checked with spectrogram and - to me - appear 
correct.

In parallel I have tried a cheap boomset with an electret-mike. That 
resulted in unfavourable reports like "sounds like a c-class-amplifier. 
Too little bias current". So I checked the bias and it is ok.

Well - I?m looking for a good alternative now, but which one to select?

Go for a Heil Proset K2? I figure, that one contains the Heil 
iC-electret-capsule. But what are the specs?

Go and replace the electret-capsule of my MD2 with a Heil HC-5-capsule? 
What disadvantages will I have with such solution regarding frequency 
response as the HC-5 apparently is a dynamic or condenser mike?

Can anybody share his experience with me?
