Best Preamp and Amp combination, interesting finding!!!

Hi all,

Yesterday, I decided to conduct a very interesting experience using my amp and preamp combinations. In the interest of fair discussion and also avoiding brand war, please allow me to conceal the name of the amps and preamps, knowing that both amps and preamps came from the same manufactures. The combinations are as below: 

Combination 1 (C1): $3000 preamp + $1000 amp
Combination 2 (C2): $1000 preamp + $3000 amp.

I went back and forth between C1 and C2 several times with multiple people, using the same speakers and DAC. The volume of both C1 and C2 was adjusted to be equal using my Db meter. 
At the end of the experience, almost everyone including me prefers C1. Which is a higher-end preamp combined with the lower-end amp. 
I was surprised by that finding. I always thought that the amp has a greater impact to sound quality, but my experiment proved otherwise. If you have any similar experiences, please let me know. I would like to understand why it happens that way. Why the preamp has a greater impact on the overall sound quality comparing to the amp?

So many logical answers fgit that data without fitting your conclusion. Three pop to mind:
1. Its a very good $1k amp and a so-so $3k amp2. You have impedance matching issues that one preamp solved and the other didn't3. the 1k amp solves a speaker match problem the 3k amp didn't (or vice-versa the 3k amp was less well matched, and apparently, speaker sensitive, which annoys me since it need not be so).
Just sayin'
Interesting finding though.
