A great simple pre-amp that sounds fantastic as a pre-amp or headphone amp. I have used this with various amps both tube and sold state and it always sounds great. I have always loved tube pre-amps and to find one with a remote at this price is unbelieveable. The remote is also first class and it all aluminum. The tubes are inexpensive and are fun to roll. One of my favorite pieces of gear and one that I will always keep.
