I know this is an old thread but here is my take for amp in the room feel and tone.
Let me start by saying I have the Helix Rack and separate foot control.
I didn’t want the separate speaker amp solution like the mission or headrush/Alto units (Both of which I have tried) I went with the rack mount amp and separate speaker cab idea, just seams much neater and the rack on top of the cabinet seems more logical to me( My Opinion).
The Amp is the Koch ATR-4502 which is a stereo rack mount init 1U.
And the Cabinet is a Ritter camper 212 again this is a stereo unit 2x12.
The sound and tone is pretty much what you get through headphones straight off the Helix except it’s in the room of course.
The Amp is 45 watts per channel so is monstrous loud if you need it.
