Hi JJ,
I decided not to buy that ELAM 251E. the seller was not able to give me confidence, even though supposedly, the mic is authentic, and in good shape. I simply got a weird vibe while talking to the guy, and he refused to give me 2 references I could talk to about him, in order to establish his credibility. he was 'offended' by my asking him for this. I get asked sometimes to provide this, and do not consider it an insult, on the contrary.
I will keep looking for a good example of a U47 and a C12, since I see that the ELAM originals are quite steep in price, and my experience with the ones I have used in the past were mixed, so this would not be my first choice in a mic purchase.
In the end, I will probably buy a mic that is close to the ELAM 251, like the Bock251 or similar ones. After I listen to it, of course...
If you know of someone who is selling a U47 or an AKG C12, let them know there is a good serious person here who won't waste their time, or will try to lowball them.
Cheers,
Nick
