Another vote for this upgrade. High end headphones enthusiasts community is now pretty large (and quickly growing).
Although I acknowledge that dCS has already covered a big chunk of this prospect customer base with Bartok and Lina, an upgrade (upsell) path to higher echelon dCS DACs would be very appreciated.
I, for one, would seriously consider a Rossini Apex if it had the Expanse feature implemented.
I was dead set on getting the Lina because of Expanse. I loved it when I auditioned the stack, but I felt it was a bit hit or miss. I also use my Dave’s Crossfeed (btw, I think I bought some dc-blocks from you earlier this year ). In the last second I got a Rossini instead of the Lina. The main reason is I was sure Expanse would not make up for the gap in performance. The second is, I ordered the Zaehl HM1, and the stereo base adjustment feature, which is apparently crazy good, wouldn’t work with any crossfeed implementation anyway. Food for thought.
