I have the Amphion Argon 3S and they are, by far, the best speaker I have ever owned. They are not cheap (at £2k/pair) but, my goodness, they are well worth it. I have no doubt that the Helium range is as good as the reviewer has highlighted here. However, I can't quite understand the 8/10?? Not sure that the cons listed justify that rating. Judging from the review itself I was expecting at least a 9/10.
