The Ultra is top of the line on everything vs the rest. Highly doubt there’s audible difference the Akm vs burr. The difference you will hear though, is the S/N. The ultra is way better than the rest, iirc only the zapco 16ch dsp has similar S/N. Requires high end everything to hit these stellar numbers.
