I am in the market for a headphone amp. The headphones I would be using with it are HD600 and SR325. The amp needs to be something I can use at home and be portable that I can take to work to use on my breaks. I was thinking something up to $400 new or used. Cheaper the better.

I'm thinking a SR-71 would serve you well for both portable use and for home usage.

I'll second the recomendation of the SR-71. Great amp!
