Entry level tube amps?

Thanks all for the suggestions. Please keep in mind that my goal is to get more texture in the midrange compared to my current amp, First Watt F5, which is rather good one in terms of midrange performance. I don't need a lot of power, as my current amp is 25Wpc only and it's plenty enough. I did hear Cary V12, although not in my system, and the characteristics is close to what I'm after.

I have CJ 16LS v2 for pre. I've always used SS power amps. I've used Theta, Proceed, Mark Levinson, and currently First Watt amp. All the gears in my system are listed in the link that says "System" next to my user id.

I like the sound of my system. The sound can be characterised as dynamic, clear, detailed, well extended to both freq extremes. The midrange is smooth, realistic, and life like. I really like the realistic harmonics of the piano, thanks to the amp from Nelson Pass.

The one thing I miss from the sound is the texture in the midrange. As I have expressed in the original post, I would like to hear more resin in the bow of cello, and reed of the sax. I'm not sure if that's all possible with the change in the power amp alone. That's why I am calling it as a trial.

The plasma is mounted ok. It was crooked camera angle. It has been updated with better and more recent picture showing current equipments. :)
