Hey all,
As kskwerl already mentioned, the design of the Asgard was changed a year ago to add an output muting relay with delayed turn-on and fast turn-off. In addition, all Asgard owners were offered the option of having the relay retrofitted into their products at no charge.
We fully understand the need for the convenience of a relay mute now, and have built relevant protection into all of our amps. For example, with Mjolnir, the chance that someone would try to adapt single-ended headphones into its balanced outputs was high enough (despite the full page warning in the owner's manual) that we built what's arguably one of the most sophisticated protection systems in any headphone amp: it constantly monitors DC level and current output, and mutes the output if any of the parameters are exceeded. This is in addition to the standard time-delay start-up and fast mute on shutdown.
Bottom line, if you like our stuff, that's great. If you like another amp or DAC, that's great too. Just wanted to clear up that one point. Now, I'll return you to your regularly scheduled thread.
All the best,
Jason
