Removing the preamps's coupling caps is a really bad idea. If the preamp is a tube preamp you will be placing several hundred volts at the amps input cap which is typically only a 16v rated cap. Also if the preamp has a shorting output mute you will then place that high voltage on the mute contacts. The minimum that will happen is a loud pop through the speakers, the worst case is blown amp, speakers.
Even if the preamp is solid state, there could be dc in excess of 50V before it's coupling cap. Damage will occur.
Leave both caps in place.
If you are looking for a better compromise solution, replace the amps input cap with a Bi-Polar cap. Amps usually have an electrolytic at the input. E-caps are not too linear unless there is good dc voltage on them. Bi-polars get around this and work very well as amp input coupling caps.
Black Gate, Panasonic and others make very good ones.
