Ok, this is a different model than I thought you were talking about. This is clearly an active preamp, and does indeed have vacuum tubes. And yes, it is not passive. They would do well to get someone with stronger language skills to write these up.
It might be ok, but one thing I do know. The vast majority of the finest tube preamps and amplifiers operate on very high voltages. This is one of the aspects of tube audio that makes it what it is. This one however only has an 18V power supply. It is cheap though. MC preamps are usually in the hundreds if not thousands.
