MHDT Orchid or Lampizator Amber 3?

@gestalt, thanks for making your presence known.  I live within 3 hours of Nashville and have a strong interest in the Amber and possibly the GA.  I may get in touch after the holidays.  I'd love to hear both of the Lampi Dacs.

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?

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. 

kalali and rx8man,  Congestion during complex musical passages can be caused by a lot of different things, and I can't know with any certainty what is causing it until I make a change that mitigates the problem. For all I know, the problem may be a function of the recordings and not my system.   Complex orchestral passages are as challenging to record as they are to reproduce.

In my case, I'm using the excellent Coincident CSL line stage, so I'm dubious about the preamp being the culprit.  Also, my amplifiers are Atma-Sphere M-60's which drive my 92.5 dB efficient speakers without breaking a sweat, so I'm not inclined to implicate the amps.  It may well be my speakers that are the problem.  But I've put a lot of effort and money into rebuilding the crossovers and treating the room, so a decision to change speakers with no guarantee that they are the offenders could prove to be an expensive and painful experiment.   What is left as most likely (in my opinion) is the Sony.  It is 2014 vintage technology, which is ancient given the rapid rate of change in digital playback technology. 

I recently read an interesting article (or advertisement) that discussed R2R vs Delta-Sigma with respect to congestion during complex passages in some detail.  Unfortunately, I can't find it.  

My current system is very good, and I'm not going to spend 10's of thousands chasing down a minor issue.  But if I get a promising lead on one of these very good DACs, I might just roll the dice. 

Uberwaltz, I agree it is difficult to know how to proceed, but in a sense, it is a nice problem to have.   One really could buy all three, either sequentially or concurrently, because all have their advocates, and therefore the resale market should be good.
