Marsplan -  Congrats on the CSP3 pre-amp, we love ours along with all our Decware gear. If the Sansui has a ''pre-out / amp-in'' that would be ideal. Or just use one of the line inputs. It will work until you get your amp. Let us know how it sounds. What is your main source you listen to? Happy Listening, Chris.

Several years ago I put my CSP3 in front of my old Cambridge Audio 30 watt integrated--plugged it into the CD inputs--and our family room system sounded far better than it ever did with the little integrated on its own.  I had it there for a few days; the difference in sound quality was remarkable!

Come to think about it, my main system is wired the same way currently.  The CSP3 is plugged into the CD inputs of a Cary Audio 300SEI and a LFD NCSE.  The 300SEI has a full blown preamp, as does your Sansui unit, so volume settings should probably be started out low.  And as hrider pointed out, an amp-in input would be even better.

Of course all of this applies to your NODE as the source.....your turntable is a different can of worms.

Good luck!
