I wouldn't hesitate. You can hear the sound it produces and you like it. For that price it's great deal. Follow your instincts.
The amp sounds great for a reason. 2 - 200 watt toroidal transformers connected to 200000 uf of capacitance. The punch and dynamics are there for a reason. You already heard what it can do. (I prefer class AB amps)
You'd have to spend WAY more $ to get close to this kind of performance. It's an incredibly good deal. Top of my list also!
