Must be an epidemic - mine is also at the Chord battery clinic for its 2nd visit. Hope to have it back next week, but can see now that there is a queue so maybe not. Still a great DAC and agree with Simon that the SQ out weighs the inconvenience. Simon is correct that Rob Watts has improved the battery performance for Hugo 2 - I posted the below in the Hugo 2 thread some time ago:
"It would appear that Rob Watts has taken on board the battery issues from Hugo 1 and users penchants for keeping the Hugo permanently plugged in for use in a main system in his design of the Hugo 2. Detail on page 131 of the Head-Fi Hugo 2 thread .
In brief, he has put in a desktop mode for when the charger is connected for more than 24 hours, which reduces the battery voltage for longer life. He claims that in this mode, the battery doesn't use up the charge/discharge cycles - so it should last practically indefinitely.
Time will tell."
