They largely look at measurements and ignore how it sounds. Most people on ASR seem to be only “measurement objectivists”. The measurements are flawed. They are not standardized for all reviews, and Amir seems to cherry-pick measurements. Also most people cannot interpret these measurements and what they mean and can only look at evaluation statement and for many its automatically “if it measures bad, its bad, it if it measures good, its good”.
As for subjective reviewers on other forums, I have not seen anybody complain about pairing Sundara with Zen CAN. For price and footprint, $150 it seemed clear winner to me that could be paired with zen dac or Magni3+ using SE (its fully balanced amp) until they raised it to $190 and its no longer price competitive against Asgard3 which only downside is backorder waiting time but it comes with 5 year warranty and has a lot more power, better and bigger volume knob. Obviously due to its larger footprint size, it almost makes you want to spend extra on Modius instead of Modi3+ just to match stack, even though as ProFalkin pointed out there is probably no reason to shop for Modius instead of modi3+. Before 3+ release, it probably made sense just for Unisom USB alone even if still going with SE. Some say Modius sound better than modi3+ but I am skeptical of it and its probably sounds at most 10% better. In that case, I think it would probably still best to stick with purchasing modi3+ and go with third party slightly longer high quality 1ft Mogami RCA cables instead of StraightWire 6" ones.
