I agree, Kandi is very talented indeed - I enjoy most of his music. The uplifting/euphoric trance genre as a whole is very speciel to me - when it's well done, it has the ability to connect with my emotions like no other style of music. At moments when I'm running in nature, riding the train through a beautiful landscape or partying with good friends, tracks like Kandi's just lift up and enhance the experience to a point where I feel so much beauty and happiness that I almost want to cry It's pure emotions in the form of soundwaves. Of course there is a lot of trite, boring stuff out there as well - but I think it's like that in every music genre. You have to look for the gems!
I think it's a good idea that you play a bit of uplifting trance in your sets - I attended a psytrance/progressive psy party earlier this year, and Atmos(who I'm sure you know!) dropped a uplifting tune in his set as well - it was a great touch!
Here's some tunes in this style I'm enjoying at the moment:

(Really nice track, mostly produced by Kandi)

As for a favourite Daniel Kandi track, it's hard to pick one, but a strong candidate for me would be "I Found The Way" - it's so energetic and powerful, with a melody that's both uplifting and melancholic: http://www.youtube.com/watch?v=K2UNgT9IVmA
I'm actually playing around with producing tracks in this style myself(I'm not on your or Kandi's level, though! ) - if you'd like, I could PM you and you could give it a listen - who knows, maybe you'll enjoy it
