They’re not asking what product you want them to build. Sounds like they’re basically asking if they make another ZEN CAN Signature 6XX that has special hardware EQ made to pair with a single set of headphones, which headphone would you chose from the selection.
Edit: And note they’re all Drop headphones, indicating another Drop collaboration a la ZEN CAN Signature 6XX.
I can see that but I just can't see how using resources to cater to a limited audience helps when their last two products have been very focused as well and the range seems to be very scattershot. The Signature and the Diablo are too close for comfort and the iDSD has no replacement.
Both the new ones are too similar as portables and in a crowded market at their higher price points they have to also deal with desktop equipment.
The current big dogs such as the RME, Schiit, Topping and others have stellar offerings at the new price points when it comes to desktop equipment.
The Black Label I purchased at launch had an Audeze LCD2 bundled for $1000 all up which was probably the deal of that year.
