You mention the VTL IT-85 amp. I had the pleasure of listening to this with a Nottingham Spacedeck, Benz Ruby, and once with a pair of Dynaudio 52SE and just yesterday driving a pair of Verity Audio Tamino X2. That is a really sweet little amp. Had no problem driving either speaker to high volume with tight deep bass. Was extremely musical and enjoyable with both speakers. A real pleasure.
