Question. If I have DAC(one RCA output) and active speakers. Can my dac input signal to789 Amplifier from RCA and use SE PASS bypass to active speakers? I hope you understand what I mean....

Yeah, you'll need a preamp to control the volume if your speakers don't have a volume control.

Yes, that's a typical example of why the bypass is there. That way your source (DAC) can be used by 2 different amps, even simultaneously.

I think that rca out is bypassing the amp so it won't impart any of it's sound signature onto it. But whether it's enhanced or not, that's up to the listener.

A unit that is designed as a preamp might alter the sound, but this unit wont act as a preamp so no change should be detectable. It just passes the input along so it can be used by additional pieces of gear.

I see. So this would be pretty useless to my LSR30X's :P

You can use this, you just have to either:
1. Use the volume control on the back of the speakers (PITA). 2. Put a "passive attenuator" between this amp and the speakers. That will give you volume control on your desktop. Some would say this is actually the best way to go because it eliminates the extra volume circuity inside the amp. If you are using the RCA's, here is one example of many that are available:
