Just to share my experience. I originally use a Denon receiver, not happy with the sound. Then I follow the recommendation to go with pre-post route. I first try used Adcom and Rotel preamp, it is greatly improved over receiver, but still not satisfied. Then i switch to Audible Illusions L1 tube pre, much much better.
I cannot confirm if it is because of the tube, or with the design. After all, the AI is a more expensive unit than Adcom and Rotel. But I am happy with the tube pre + SS power amp combination. And I am not implying tube pre + SS power is better than all tube configuration, it's just I have kids, and the tube power amp is not safe with kids around.
