Preamp or power amp has more impact to resolution?


Dear all,
If I want to increase resolution of my system, which upgrade that can provide more impact, pre-amp or power amp?

Thanks in advance for any advice

Need to have more information about your stereo. Type of speakers, amp, and preamp, and your source. Good Luck
Unfortunately not that simple... It's a chain from source, per, power, to speakers. And it depends on the speaker load... Very difficult to drive speakers will require the right amp or nothing will sound right. Easy to drive speakers and the pre becomes increasingly important.
Agree with the above; that said I have found many more amps that I liked than preamps. It would appear that amp design is better understood than preamp design or else companies spend more time on their amps. Just my experience.

The detail or resolution needs to be picked up at the source before the pre-amp can amplify it and then the amplifier to amplify it yet again. So IMO it really starts at the source because you can't amplify what isn't there to begin with.
