Opinion on the Pro-Ject tube box 2

I was thing of getting the pro-Ject Tube box2, was wondering if anyone has one and what they think of it. How does it compare to others in the sub 500.00 range. And if you think it needs an upgraded power supply. Also i should note i am choosing this over the SE for two reasons i want to see the glass, and would like to use herbbies tube dampeners.
My brother owns one, and likes it very much in his system. He brought it up to my house a while back, and we compared it directly to my Bellari. In my system, the Bellari was better - bigger soundstage, better resolution of timbre.
