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?

Preamp transitions in my system have been the hardest of all components. Beyond the obvious sonic signature at a "macro" level, they also do a zillion subtle sonic things that gets ingrained into your perception of sound over time. With phono stage and amps it's either instantly "yep it's better" or "nope it's not" and that's that. 
Well frankly it is really pretty meaningless except for the specific gear tested. What were those again?  Also price alone means nothing except how much you will pay.
This thread seems borderline meaningless: whereas the preamp is crucial on low voltage phono, all you need for high voltage digital is an attenuator in a reasonably well matched system. And that before you even start accounting for mismatches between preamps and amps: Dooh….
I suggest: don't over-generalize! What you've found is that in your system, with your room, your source material, and your speakers, that you and your friends prefer C1 to C2. Useful information! But what you have not found is anything more general than that -- nothing about results in other rooms, other systems, other speakers, other musical material, and **especially** not other components, even those in the same price categories.

It is a human tendency to generalize from a small amount of data. If you can limit your conclusions to what you actually have found, you'll be way ahead of many.
