MHDT Orchid or Lampizator Amber 3?

Bill and Chris, thanks for providing all the info on these 3 wonderful (by all accounts) DACs.   I'm thinking seriously about giving one of these three a try before the end of the year.  

I've read that R2R chips tend to handle complex musical passages better (less congestion) than Delta-Sigma chips, and since I listen to a lot of orchestral music, that is a big issue for me.   I'd be especially interested in any thoughts either of you might have regarding how the Delta/Sigma Amber stacks up vs either the Orchid or the AM, which both use R2R chips, as far as handling complex passages.
 
Thoughts on this issue?

@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).

I don't have either DAC, but wonder if your assessment of the Amber might have been different had you had the ability to get it to the 200+ breakin hours given comments grannyring has made about its sound has he has gotten closer to those hours

Certainly possible, although I also felt that the two dacs sounded very different from one another. Obviously Lampizator thinks you can get a pretty good idea of what the Amber offers within 7 days. And as Bill pointed out, everyone's impression is so totally system dependent.  If there were one single best answer, this forum wouldn't even exist.

Chris, you are absolutely correct in observing that implementation is key.  Also, there is never going to be a single DAC that is unequivocally better in every attribute.  It is enough for most of us that it checks most of our personal boxes, and mates well within the context of our systems.  In my case, my ModWright Sony lacks only in one respect, that being how it handles complex musical passages.   Tonal correctness, imaging, vocal articulation, air, liquidity, dynamics, virtually every other attribute that I value, is very satisfactory.    Hence, any DAC that becomes congested when asked to process a Mahler full orchestral onslaught is not going to find a home here.  The AM that you are keeping is still a serious contender for a mid to late 2020 purchase.  So anything that you can offer in that respect would be extremely useful information.
