no volume control was used, all at 100%, for me the volume control takes away dynamics.
They will not tell you about some things, like tonal equilibrium, subjective transparency, subjective dynamics in the upper bass area, weigth of femal voice, decay of string notes, etc. THD and noise floor are not enough to rank a source, imho but that is off topic. It is a subjective test with a friends grup. I am more in the Planet10 camp though the bass and upper bass area should be very correct with the Tannoy. That is still educative.

I know that Tannoys are often used as references as they tend to provide a stable point. The Westminsters i heard were so coloured i don’t know if i could listen thru that. One really needs to try a variety of electrical to acoustical transducers.

This was subjective listening comparison, right? Since you didn't specify it, I wanted to ask.
The absence of digital filtering has nothing to do with a preference for delta sigma. All your multibits are NOS which appeals to a very particular taste.
With dacs implementations matter a lot. You cant say the op and friends were listening to the chips themselves but rather the surrounding circuitry. From the pics one dac has cheap chinese output caps (the dreaded red ones) while 1541 is trafo output- thats already a big discrepency favoring the 1541 unit ect.
Yeah i'm torn here. Other than mentioning a fair test is not really possible here, as there is no way to implement all of them the same. Just using the same source is not enough to make this useful and certainly not objective... lol.
Possibly the closest you could get is to implement all IV stages as suited to each chip/device and power supplies of same caliber, but use the same voltage buffer for following all. Whether that would be audible? hmmm
as the IV stage is integrated into Andreas discrete, that is not possible.
(note that I dont favour the lego block approach, so I feel dacs should have integrated output stage designs on the same PCB. there are certainly better implementations of ESS dacs)

Partly. It works with current sources and current switches. An R-2R network is used for generating the scaled currents for the current sources for the lower bits. The current sources for the highest bits use a special DEM technique.
