I thought so...
This means they listenend to you, but not to my efforts with the list. So totally useless what I'm doing.
I'm sure that's not true. My guess is that they're absorbing user feedback and bug reports, which is obviously now coming fast and furious now that so many users (both head-fi and "professional") now finally have an A16 in their hands and are actually trying to use it. And they're dealing with everything in some priority order, as they see it.
You see how quickly they addressed genuine major show-stopper bugs and problems, such as "the buzz" and the "stutter" related to navigating CD audio fed through HDMI. And now with 1.75 they've made some very useful user-interface enhancements that they probably never realized were so important before our feedback.
It's one thing for developers to use the device in a lab or on a programmer's desk, or for occasional demos, and another thing to see how a real user uses it in a house or theater or bedroom environment. The screen is small, and close-up it's readable but from five feet away or more it's essentially impossible to read menu items. So being able to use the remote "in the dark" through finger-memory, and not have to depend on reading tiny characters on a screen... it clearly becomes much more fundamental and important when you have "ordinary civilians" (including family members) try to use the device and get frustrated with the amount of tech-savvy required.
So (a) not being able to have INPUT implicit in a preset, and (b) not being able to select a preset "in the dark" with a fixed single button (like the P1-P4 of the A8 remote)... these now are BIG DEALS, just as big as "the buzz". If you can't just pick a preset "blind, single-click" and have its default INPUT automatically likewise selected, well I guess they just never realized how important that would be until they left it out and users began complaining.
(I suppose the SVS Bass will still be flawed and produces strange distortions. But seems that I'm totally alone with this, no one else even bothers to test this at least.

)
As the user community really begins to grow, I'm sure there will be lots of "exotic" features that surely will be very important to some but not to others. And this will definitely influence the intensity with which you experiment.
For example, my own focus is on USING the A16 (with my pre-existing A8 PRIR's). I have never actually "created" a PRIR myself (since Lorr "engineered" mine at AIX), and even today have zero knowledge of the steps involved. Hence my focus on good and bad points about the user-interface, for USING the device.
I'm sure Smyth will continue to respond to all of our inputs, over time, in reasonable priority order. Pretty remarkable what "biggies" they've already managed to successfully address. And I'm sure tweaks and improvements will continue to come out, even when a first step was good but not quite right.
