Hi, here's the new model. Seems like a real beast:

I had the opportunity to try it in a showroom with HE400i/s some days ago, and initial impressions were really positive: great sound, powerful, sturdy and well built. And, considering the price, a real bargain: 180 € bought directly in Spain.
 
As the are totally different models, I think it could be interesting to open a new thread but, as I'm new here, I cannot upload photos, so it's probably better that someone else do the task.
