I wouldn't avoid it like the plague at all. For what the op wants to spend, this would be without a doubt one of the best options around. The are many threads backing this up. If the budget was $500, it would be different.
The Zero dac is also a great sounding dac/amp and sells for abut $130 on ebay. I would recommend that highly for the money. Powered my hd650's suprisingly well. Awesome bass too.
