@knik, the Rogue is actually very full in my system. Compared to the XP12? The 12 was very focused, pinpoint really. Not in a bad way. Overall sound stage was great, but center focus was tight. The Rogue is focused as well, but in a different way, not as pinpoint. Wider soundstage, and seemingly deeper as well. Low mids are rounded, and full to me. Again, less punchy. However, overall “slam” is very good. Keep in mind, this is the only tube preamp I’ve tried with the XA25, but for now, it’s a keeper. I need to stop with the crazy for a bit!
