Parasound Zpre3 anyone?

I have the companion Zamp3 which is highly reviewed and acclaimed, it's all true. It's an amazing little amp for the money. I'm wondering if the pre is as good as the amp, not much info out there other than very positive reviews on AudioAdvisor. The picture of the insides makes it look like garbage but hey...you never know. Sometimes things just sound great...regardless of opamps ;)

This is for a second system.
