I have been intrigued by the tube sound for a while (I remember what they sound like from my childhood years), but I only upgraded to a Musical Fidelity amp driven by a Rotel pre-amp a couple of years ago. On the whole, I'm happy with this set up, but for some types of music, ie classical vocal, violin etc, I wonder if I would get a warmer sound if I introduced tubes? I don't have the money to change the whole set up, or to set up an alternative system, but thought I might experiment with a tubed pre-amp just for certain uses.

Has anybody else mated a ss amp with a tube pre-amp? Is this a successful comination?

Thanks.
