Thank you. That implies existence of multiple filter banks. Would you be able to look a bit closer and report back?
Quickly done.
Yes, EKIO can have multiple configuration settings at once (each config has ".ekio" suffix when saved in EKIO folder), and within EKIO we can Name each like "sample config1", "sample config2", "sample config3", and so on.
After launching ABX comparator, we can assign any of them to Config A and Config B for ABX comparison;
Even we can assign same one for Config A and Config B, of course.
Very simple (and rather traditional?) but well designed ABX comparator, I assume.
Consequently, EKIO has "
Unlimited Numbers of filter banks" and "
Yes ABX comparator".
BTW, within EKIO, we can quickly change/select the "internally named" configurations,
i.e. "filter banks" you mean, but not seamlessly on-the-fly while listening to music; when I change the "filter bank" while playing music, EKIO stops playing, and I need to push "play" again under the new "filter bank"; I assume this was so designed for safety concerns.
Even I do not know about what do you mean by "
ISO226 volume control", EKIO does have "volume control" of 0.1 dB granularity in
Input Channel gain control; I usually use JRiver MC (or DAC8PRO) as my master volume controller, though.
