I appreciate all the comments, guys. Thank you to all who have posted their opinions on the differences...especially on the sound signature of both the 5K and ES100. Personally, I like the AKM Velvet Sound dac chips in the ES100 (as well as the AKM 4490 in my Fiio Q1MK2). When I read from others that the 5K can sound fatiguing, that makes me rethink that purchase. I love my ES100 because it's NOT fatiguing and I can listen to it for 2 to 4 hours on end. Based on what others have been saying about the 5K, I'm not sure that I would like that type of bright and forward sound with the majority of the iems I currently enjoy.
