That is interesting. A fault in the documentation I'd guess. When I had the VAmp, it operated exactly like the Go-DAP 4.0. The only differences were the pre-fixed EQ tweak (the Go-DAP's ASR vs VQ mode or whatever that's called in the VAmp).

I want a portable DAC to pair with my C5 and the only options are the CLAS and the DD afaik. I want to get a DD but that functionality quirk may be a deal-breaker. Why would they implement the DD in this weird way?
This is -entirely- speculation 'cos VentureCraft has had this since the 4.0 - whether it was rushed out the door to compete with the then HP-P1 or original CLAS, or some weird circuit design that got into production and too late to back out, only they know. Presumably instead of redesigning with their subsequent models, they stuck to their fundamental design and just tweaked for each product.
This is where the Typhoon could be interesting since it's using a different DAC chip which means they do need to do quite a bit of redesign.
