I've owned a 275 tube, 402 SS and C2300 preamp all at the same time. In my system the tube amp was more transparent than the solid state. Although the 402 had much better control over the speakers (Quads & Wilsons), it sounded a little veiled especially at the frequency extremes.
Regardless of the amp, the C2300 was excellent with a very good internal phono stage. The preamp was extremely quiet and transparent with no tube noise.
Overall my preference was for the tube amp, but it just couldn't drive my new speakers appropriately.
Once you break in the C2300, try rolling the tubes. If you are not using vinyl, you only need to change out the 2 line stage tubes. If you will use the built in phono stage, you will want to change those tubes as well. I particularly like Telefunken.
