I had a Decware CSP3. It was a lot of fun tube rolling the input, output and rectifier tubes. It has potentiometers on the input and output tubes that further affect the character of the tube sound. You can make it lean or lush depending on your taste and your system. It has a lifetime warranty that can be transferred for a fee but the rig needs to be sent back and will be brought up to spec if needed. Look for a used one on the Decware site.
I am now on my second used Allnic Pre-amp but still miss the fun of the CSP3.
