Based on your likes and dislikes above, you might want to take a listen to the ProAc Response 2.5's. I have them and think they have all the qualities you mention, but offer a somewhat better sound than the Grand Piano's in my estimation. I spent quite a bit of time auditioning both the GP's and the 2.5's with a variety of electronics, and I enjoyed both of them, but in the end walked away with the ProAc's without hesitation. I've paired mine with tubes, but the designer recommends a solid state amp (the ARC 100.2) as his ideal pairing. As a caveat, I should mention, there's about a $1k difference between the two, which depending on your budget may make a difference. Anyway, just some food for thought.
