Are Preamplifier’s Relevant Today or just a Hinderance with Digital Playback ?

The digital controls must be able to drive the amps you are using.  Some may sound very good but overall from my experience with the MSB and the Rockna DACs with digital volume controls, the preamp added much more dynamics, clarity, depth to the soundstage, better separation between vocals and instruments and faster more pronounced bass response.

Happy Listening.

@jond,
Yep, couldn't be expressed  any better.

My experience matches "bigkidz" but with different equipment. That said, IME a good preamp will enhance the listening experience (clarity, soundstage, etc.)

@charles1dad Thank you Charles, I still don't know why things are but sometimes I know how they are. :)

Also, cables between preamp and amp should be at least as good as on the source.
