Jantzen Wax Coil or Mundorf M-Coil CFC

Inductors make a MASSIVE difference in sound quality, as much as capacitors.
The Jantzen Wax Coils are dead silent and have a black background, and have amazing dynamics. Get the 12 gauge version...

I know this post is 5 years old, but I had to correct the record. And yes, the wax coils are a serious upgrade over the mundorf plastic coils. The plastic coils are noisy, they have a harsh ringing in comparison to the paper wax housing. 

ADD:
The main difference between the two is in their Timbre. Jantzen wax sounds rich and velvety, perfect for jazz, acoustic and classical. The Mundorf sounds drier and faster in comparison, good for EDM/trance.
Both are copper foils, the housing makes a pretty dramatic difference in the sound both produce.
If money is not an issue, Duelund Cast is the best inductor on the market.

ok. So no need for fancy inductor?

If your hearing is bad and/or your system lacks resolution, you don’t need a fancy inductor. If you want your speakers to sound good, have a natural sound and resolve detail, you need a fancy inductor.

Yuviarora, interesting.  I am considering Jantzen wax coils versus Mundorf, but don’t know what you mean by “Mundorf plastic coils “.  Mundorf’s best foil air core is “Copper Foil Paper”, is that the one you mean?

Timely posts for me! I purchased both Jantzen Litz wire wax and Jantzen solid wire inductors some time ago as final mods for my Klipschorn crossovers. Can't recall exactly why I purchased both solid wire and litz wax wire, seems I remember something about litz being preferable to solid for tweeters, or maybe I have it backwards. Can anyone inform me as to preferences here?
