I'm in the same boat as -chino-. Been using UX2 for years, and recently downloaded the Helix Native trial. I set up the Helix Native plugin in Ableton, and it seems to work great with no perceptible latency. I really only plan on using this in my office while recording right now, but do want as good of quality I can get within reasonable constraints. I'm wondering if there's a quantifiable reason that I should use a newer audio interface than UX2 if all I really care about in the interface is the quality of the dry signal that's output (specifically looking at the HX Stomp and then the $99 Helix Native upgrade)? -chino- mentions dynamic range could be an issue. I did some research, and see that Helix LT, for instance, provides "Uncompromised Helix sound quality with 123 dB of dynamic range" (per Line 6 website). Only thing I can find on the UX2 for this is the relative statement that "UX2 provides the lowest noise for recording guitar with 12dB more dynamic range than similar interfaces". If dynamic range is a factor, does anyone know what the actual UX2 dynamic range is? And are there any other specs that can be used to compare quality of purely the guitar audio interfaces (excluding number of ports, mic, midi, software, etc)?
