I have a VTL 2.5 tube preamp paired with Bryston 3B Cubed. I use to have a Bryston Bp25(sounded great), I really like the tube pre, but it could be my older more sensitive ears just finding the tube combo less harsh. My ears are not as accurate anymore. It might be a more coloured sound, but I'm enjoying it. That's all that matters in this hobby.
Happy listening..........
