Need a preamp?


Hi all, 

I have an older Cary tube preamp and a Bob Latino ST70 with a built in attenuator driving a pair of Proac D30R. The combo seems to be a tad too warm so I tried using the amp without the preamp and it seems to sound better with a wider soundstage and more extended highs. I have a phono amp also so I can also listen to LPs and cds. Is there a reason I need a preamp other than the convenience of switching between the two?  Would a ss preamp or passive preamp add to the sound?  I presume any preamp would only degrade the quality and can't make it better than it is.

I was thinking of using the Schiit sys and leaving it on full volume and use the amp volume control. Would that function as a switch box or is a dedicated switch box better? If so, what's a good switch box?
After a few months, the feel of the schiit controls does not inspire confidence
jaferd, I’d say for $49 and the option to return, the Sys is a no brainer. My comment regarding the quality of the volume control was meant after extensive use. Otherwise it’s well built and functions as it should.
I am with Atmasphere on this one, having gone passive ( permanently ) 2 years ago, and having a few units.
