I think I was one of the ones who posted in that "other" thread
I don't think you'll get too many Little vs. Creek responses, because few people have actually owned both -- they're in a similar class, so if someone is going to "upgrade" they probably won't go from one to the other. I've owned the Little, but never heard the Creek.
The Creek has lots of fans, and is allegedly a great amp for the price (especially the SE version). That said, what I brought up in another thread is the upgradability of the Little. You can buy the Little by itself for less than the Creek and get very good performance. Later you can upgrade the power supply, the electronics module, etc.... little by little (no pun intended). Eventually you'll have an amp that is FAR better than the Creek.
It's this upgradability that I like about the Little.
Has anyone heard the Little and Creek side-by-side?
