Jafant, I have used 2 models, MI 2 and MI 3. I prefer the MI 2 model to the larger AWG 3 although the comparison might not have been fair. The MI 2 has silver spades and I ordered the MI 3 with Rhodium spades and I believe that termination is inferior and resulted in highs a bit on the harsh side.
The MI series is copper, I have never tried the AG models.
