Thinking of changing my solid state pre amp

I use a C-J MF-2550 for my amp and Totem Winds for my speakers.
i listen to whatever my family will let me get away with as far as music goes, and nothing too loud unless someone wants to dance.
i can’t break 5 digits for my budget.

Thanks

I will never get rid of my C-J. They r champagne golden in my book.
i would like to play a little, and try some other brands out. 
But my amp, I think that’s my home run piece, really.

Changing the tube is a really nice idea. Another step in the audio journey...
everyone has been great with ideas. My 13 y/o son & I have been talking constantly about choices, thanks for all the input.

Decided to get a C-J ET-5.
have been really happy with it.  A bit better build quality and a bit better response from my system.
