Amplifier Modification

Can solid state amplifiers be modded to obtain higher input impedence, so that they can have a better chance at matching with a wider variety of preamps, specifically tube preamps?

By adding deeper negative feedback and adjusting bias(offset) current accordingly.
You will then jeopardise stability of the amplifier for good and will need lots of trial-errors to get it stable.
Highly UNrecommended procedure.
