I used to enjoy the natural sound from Kevin's digital products and I owned several. High Resolution Technologies was Kevin's last company (that I have heard of) and they designed small DACs that they called streamers. Here is a review. The HRT website no longer seems to work. Hopefully, the telephone number below survived.
