The Shindo is a more musical preamp with a richer sound then the Red Wine, however, you have to way if the system is going the right direction, the Devores are not exactly bright sounding speakers either.
I am really surprised that so many audiophile here do not know that there is an American made, modern preamp which has remote volume which offers the same sonic qualities of the Shindo, and it is less expensive to boot! The Manley 300b preamp which I would urge you to hear, I have one and it rocks!
