No, reamping means that you take a line level signal (anything you have previously recorded) out of your soundcard or what ever, and connect it
to a reamp box that converts the signal to hi Z, wich means a high impedance
signal. And that means the signal now is like a signal that comes from a guitar, bass or keyboard. This is a cool thing and can be used on many
things. The most popular is of course to reamp guitar. When you record the electric guitar you plug the guitar direct in to a DI input of your preamp or soundcard (Hi Z DI input) and record. Then you plug a balanced line cable from a balanced out of your soundcard into the reamp box, and from there you connect a regular guitar chord (unbalanced TS) to a guitaramp and rerecord the guitar through the amp with a mic. That way you can first record your guitar at home and not disturb anybody, then you bring your laptop, soundcard and reamp box to your rehearsal studio where you can crank up the volume and rerecord the guitar as loud as you want and get some nice amp distortion.
A reamp box can also be used if you have some nice effect pedals you want to use, for instance a MXR phase pedal on a mono drum overhead mic

Or a vocal track trough a dist pedal, sure beats most amp simulator plugins!
Your mind is your limit...
And by the way, FiveFish preamps are a very good for the money.
I hope I made some sence...
