  1. Since you've introduced so many speakers, do you have a personal favorite?

    1. Hi Ding,

      I don't have a favourite speaker. I appreciate a lot of different speakers and amplifiers as they are - listen to what they can do, don't try and force them to be what you want.

      I do like vintage alnico speakers, but I'm OK with ceramics too. I like a full sounding speaker with a good bass response, nice detail in the midrange and smooth highs.
