Big sound in a small package!

The following review is for a previous version (C421).

After using this amp, and experiencing nothing short of "musical bliss", I would surely recommend it. Right out of the box, this little amp had my headphones rocking like never before. It feels really solid, looks really good, and sounds really great! The people who made this amp really put a lot of thought into it. It shows. You can charge it multiple ways, use it as a desk top or portable, and it let's you know through colorful LED lights its status. It can drive all headphones with ease. I have several and I'm a witness! I really have nothing negative to say about it! Do yourself a favor and get one!
