Wombat3 I have no experience with any of your gear, but I'd like to recommend that you audition a Simaudio Moon I-5 integrated. I've owned one for almost a year now, and am very happy.
I would characterize it as being fast, detailed, smooth, and dynamic, with good extension at both ends and a huge soundstage. If your associated equipment leans toward the thin side, it may be a little too neutral for you. But it's a good amp for bringing life to a dull system.
Good luck!
