@brownsfan Unfortunately the closest I get to classical on a regular basis (or during my auditioning) is electronica, so I don't really have much to say. Hopefully Bill has some thoughts. I started to write about the imaging/soundstaging of the two dacs (Amber = wider, AM = deeper), but I don't know that that really relates. As you've seen in my comments, I did find the Amber to be more incisive and could imagine that relates to a better delineation of many instruments playing at once. Wish I'd given some classical (or maybe some complex instrumental rock like Battles) a listen.
I will note that across the DACs I've experienced in my system, I've heard Wolfson, DS, ESS, Analogue Devices R2R, a FPGA, Brown-Burr, and Shiit's multi-bit implementation of two AD chips. Unfortunately there's not much overlap there, but I did find the two AD chip based units sounded very different from one another (more so than the AD R2R - Audio Mirror - vs. Brown-Burr - iFi iDSD Pro- for example). Much like amplifiers, I suspect there's more to the implementation than the chip specifics. I know Lampizator doesn't want your DS prejudices to color judgments of their products (and hence are hesitant to even note what chip they use).
