Adding pre-amp to an integrated amp?

I am using an tube integrated amplifier. From some immates in a newsgroup in Hong Kong, they mentioned the addition of a pre-amp. to the integrated amp. (treat the integrated amp. as standalone power amp.)and its performance improved. Does it make sense to amplify the signal twice and resulting in better sonic performance? Hope the immates here to throw me some light on this.

Perhaps this it what they are referring to; some integrated units have a set of U-shaped pins that can be pulled out. When that occurs the amp/preamp can be used independently of each other. In that case, a better preamp could result in better sound.

I agree with LAK. I doubt they are double processing the sound. Some integrated's also have an additional pre-out so you can add a second amp and Bi-amp using an integrated. NAD, Cambridge Audio, and Rotel's for example.

Nope. They are using the same integrated amp as mine. It don't have a pre-out. To my understanding, the immates just plug the output signal from the pre-amp to any of the inputs of the integrated amp. This resulted in double amplification of the signal. That cause my posting of the questing.
