Kazuhito, have you ever heard them with Onyx integrates (the original ones from the original designer)? Magic. I hate selling the two I have left, but I need to pay for new Vandy's I'm getting. They are inexpensive and I have A/B'd them vs the Naim and everyone in the room chose the Onyx. I was surprised, but that's how it played out. Sugden is a good choice. I like the Brio too, but feel that the Rogue stuff (new ones) sound better as they have that mid magic that the Proacs kind of need, as do most any British speakers.
