Using the Jolida Int. as a preamp would make no sense. It is virtually an amplifier with a Alps volume control. You would only be using the volume control as your preamp and would get no effect from the tubes.
You could use the Jolida or another tube integrated and do away with your amp. Tubes for the amp will definately give you the tube sound also.
