Amplifier for D2904 + TMTs

So I’m super enthusiastic about my Helix power amplifier, but I have a problem with it, the performance is missing. At the moment my front system runs fully active (separated from HU) on my Helix. Jetz I have 2 possibilities: 1. I throw out the Helix and get me a 4 channel with power 2. I get a 2 channel for the TMT and keep the Helix for the scans or someone has a different idea best I want to get something needed, because I have too much money I also have a problem. he signature can see the trunk expansion, I have only limited space available!
