Melody SHW1688 anyone recommend it?

I'm looking for a good tube-preamp for two Nuforces 9 driving Apogee Duetta's Signatures. I want to put some musicality in the system as I feel with the Nuforces the system lacks in that departement. I've read some positive reviews of the Melody SHW1688 preamp and like the build of this product. However as it is a chinese brand I cannot audition it before buying so I would like some input from this auio society. Maybe other recommendations to put some sparkle into my sytem. I also thought about buying a DEQX unit also but I have the feel this wouldn't be what I'm looking for.
