Little Dot I+ 6CQ6 X2 Tube Upgrade Hybrid Headphone Tube Amplifier

I love it, especially for the price.

I was reluctant when I saw "Hybrid" in the product description. So I did my homework, looked into the internals by opening one up and looked at the build quality as well as the parts used on these items and found them to be good quality components. For sound quality the 3 is because like a lot of the tube equipment it comes with Chinese tubes and they really sound blah. After putting a pair of Riverstone Audio - Tested/Matched Pair of tubes in and then allowing for some burn in time this unit has really come to life and produces exceptional sound. If you buy this and change the tubes you cannot go wrong for the money. Hope this helped. Peace.
