This is the series 1. I am the second owner. I have had it for about 6 months. It was purchased from the UK. The original owner bought it from a dealer in Switzerland and had them set the unit to 240 volts. It can be set to 110/120 volts with a switch inside the box. This is according to Berkeley. There is no need to send it back to have this done. This unit is in excellent condition and was used in a smoke-free, pet-free environment.
One Audiogon poster noted the following about the series 2 Berkeley Alpha DAC that he recently purchased: it offers "subtle changes rather than anything major." Sometimes reviews exaggerate for the sake of being up-beat. The series 1 is a great DAC.
