I use a pair of Stratos monoblocks in the "glass ceiling mode." Use any one of four different tube preamps ahead of the amps. The speakers really show their design with a good turn table playing acoustic jazz. Seriously duplicates the reeds vibrating in a tenor sax, and does piano about as good as one could ever ask for. Vocals are very good, and would place them right in there with my old Meadowlarks (known for their vocals). When you first hear drums thru them you'll say to yourself "they get them wrong", but go listen to the real thing. Drums are tight with only the snares vibrating. Yet the upright bass rumbles like the real thing.
