I'm on my second trial of the 15 days Helix Native demo. The first time I tried it I thought it was better than HD, for sure, but I was not overly impressed. However, this time I have spent more time trying to recreate the 4-5 basic presets I use on my HD500, sitting on my couch with the Helix native on my HTPC, connected to a Yamaha amplifier and a pair of B&W speakers. Dude... I could not stop playing. The Helix sounds glorious. And I have not even tried to use a single IR yet! Of course, playing with a computer is not the best way to enjoy the Helix platform. The Native is really meant for re-amping. While Latency was not too much trouble, sometimes hiccups happens. Something tolerable to play at home, but not for a serious use live. Still, I really enjoyed the sound of the amps, the delays, those impressive emulations of distortion pedals, the studio compressor ... I'll wait for the next NAMM in case there's any interesting news, but now I think I'll start saving and putting my HD500 up for sale, now that the price of Helix and LT seems to be somewhat lower in Europe.
