I am interested to hear from any one who uses this above DAC. All the reviews seem positive about its build, features and sound quality. From my perspective currently I am using a Sony £20 headphone via my lap top, I want to improve the sound quality and I listen to many genres of music. I have finance to purchase this above DAC but would it improve the sound quality via my headphones or would I have to get more expensive headphones like the ones all used in various reviews? Also if I would get the above DAC I would need to use a headphone Jack adapter would this diminish sound quality?
