Input: Update....bought two. Both died in a month sounded great then.....junk This is the best purchase of the year! It's a simple little tube pre-amp, but wow this thing opens up the soundstage and warms it up with a good headset. It's just plain fun. I didn't tube roll it or modify it , because it sounds great as is.... considering the price. Have fun.

Read the update..My favorite thing I purchased this year....
