Good day to all! (1/1/2015 - Obsolete - we have added so much more options now, email to ask for more options!)

We've received a question from our followers: "You have so many types of transformers. Which one sounds the best? Can you let me know the ranking to make my purchase decision easier?" We hear you. So, this is what we rank our transformers from top down:

3. Normal silicon iron C Core
4. Z6 - Z9 - Z10 - Z11 EI Core
