I'm currently enjoying a Kavent S-33 preamp. It has 1 set of Balanced inputs to go along with 5 regular inputs. It also has 2 pair of outputs and a set of balanced outputs too. It is very similar to the Vincent SA-93 preamp. The remote is very solid as well and can reduce the gain by -10dbs.
Another preamp if you can find it is a McCormack TLC-1 with remote volume control. Very rare but it does sound good too IMO.
