Guys, I would like to share with you my findings about reamping, through personal experience and trial and error. Sorry for the long rambling :)

Here we go:

Recently I've decided to do a couple of recordings and see what comes out of it. But I don't have a studio or an isolated room, so in order to not to disturb people around me all the time (with too many takes and recording at odd hours) I've decided to record silently and directly to DAW and then play around with amplitube as a first step. This way I could do as many takes as I want until I get the perfect track and then reamp it at a later stage. Amplitube is more than enough at that initial stage for me to arrange the song and get an idea of how it will sound.

However, I also didn't want to lay down 10 songs or whatever and then find out that reamping was not going to work and record everything all over again. So after recording one practice track I decided to see how it would sound reamped. Then came the problems :)

There was loud hiss and a bit of buzz coming out of the cabinet. I disconnected the input to the amp and there was no noise. To be honest, there was little hiss coming out at louder volumes (and I figured that's the natural hiss of the amp) but nothing like when the reamp cable was connected.

So I started to experiment. The chain was: Laptop/DAW - Focusrite 2i4 - Balanced Out to Palmer Daccapo Reamp Box - Then Daccapo Isolated Output into Amplifier Input. All power cables were connected to the same outlet. I don't own a power conditioner by the way.

First, I tested how much noise there was with the amp when a guitar was connected and it wasn't much. So there was definitely something wrong. First thing I found and that lowered the noise noticably was disabling the laptop's internal soundcard and just having the focusrite enabled. Then I experimented with volumes by lowering the volume on Daccapo and on the Focusrite but that definitely lowered the gain of the recorded track as well. So I had to leave the volumes at exact level that my guitar would sound like when connected to the amp, which was around noon for both Focusrite and Daccapo. I checked the recorded track (playing through monitors) to see if there was any noise issues from the original take but there were none. Moreover, with the DAW closed and nothing playing the hiss was still there.

After a bit of research I realized disconnecting the laptop's power cable and running it on batteries fixed the issue. Since that was not very convenient for me I went and bought a Behringer HD400 Hum Destroyer and now with the laptop power connected there is no noise issue. The little bit of regular hiss that remains (same hiss when a guitar is connected to the amp) I fix it with a gently applied noise gate in the FX loop of the amp.
