I hate having to purchase something as subjective as hifi products without auditioning, but in this case I don't have a choice. I'm looking for a DAC that can do duty both as a main system one and as a portable device. The Chord Mojo seems to fit the bill and gets rave reviews from the UK press. However, other non-UK reviews seem less enthusiastic. I'm in Tanzania for the next 18 months, hence the dilemma. Any better options? TIA.
