How to hook up a preamp to a Integrated amp

After looking online, it appears there are different versions of the integrated amp. 1) Has no main amp input and using another preamp is not possible. 2) Has main amp input with toggle switch. 3) Has main amp input with jumpers to output. Which version do you have?

Thanks for the info . Mine has no main in . Thought it seemed impossible from looking at mine . Shoot ! Just got the Int. a couple days ago and like but seems closed in compared to a Sim Audio p5 /krell ksa 100 combo .

And you are welcome, glad to help.

You could connect the preamp to one of the integrated's line-level inputs.  While that would amount to having two preamps in series, and from a philosophical standpoint keeping the signal path as simple as possible is usually to be preferred, that arrangement would certainly function properly, and very conceivably could provide fine sonics.

In doing that, the volume level would of course be affected by the controls on both units.  Just be sure to avoid turning up the P5's control far enough to overload the LSA, which I see has an input overload point specified as greater than or equal to 2 volts.
