I am inclined to agree with Mambacfa--you will be happy with almost any high end phono stage. Many do sound good and are relatively similar as compared to the more widely varying sound of amplifiers; line stages lie somewhere between phono stages and amplifiers.
I haven't heard the VTL model you selected, but, the company has a solid reputation.
While many of my favorite phono setups do use step up transformers, I don't think it is a necessary approach. I've heard the Atmasphere preamps and they sound very good to me despite my general preference for a lot of iron in everything.
