Looking for a 6SN7 preamp, any word on Space-Tech Laboratory?

Looks like the WP-1 is just what you’re looking for.  There is a member here that has some gear from Space Tech Labs. He speaks quite highly of them.  Hopefully he will jump in. 

I own a space tech labs QA112 preamp a super rectifier and an older model DAC. I'm very happy with the sound. I have the preamp paired to a Krell ksa 300s and apogee duetta 2 speakers. If you buy a space tech preamp get one with a tube rectifier, and the 6sn7 signal tubes. You can add a super rectifier later, they make a big difference, even though the preamp sounded great without it, it's much better with the super rectifier.
