They are surely reaching the position where processing power is an issue. Having said that, it’s the only modelling hardware platform out there that has remained in the top tier for anything like as long as it has. The Fractal platform would have cost you a fortune in that time so give Line 6 some (a lot) of credit. The new EVH5150 IIiis the best model of that amp I have ever tried, and I’ve been down the fractal platform, and currently have a quad cortex for the studio and captures. Trust me, that unit doesn’t get near the Helix in a live environment. As it stands the helix is still an outstanding unit and frankly I’m amazed they are still adding updates. When they eventually bring out a new platform, unless it is as functional as the helix as a standalone unit in a live environment I wouldn’t be upgrading.
