OK - I have morphed Hifi_swlon's good work into my own list, see below. (it has lost a bit of formatting having been cut and paste from Word) I have sent a copy to Alasdair, hopefully he will chime in an let us know what he has done with it! (other than hit delete and proceed to the pub)
Expert Pro / General.
1) What is replacing the current Expert iOS volume control, and when’s it due for release? Also, please consider keeping and updating the current one, the design is great and just needs updating for current iOS, iPads, and add a few extra controls (like tone, SAM).
2) What are the plans for the web based configurator onboard the CI? Will it evolve to replace the current internet configurator, and ultimately remove the need for SD card configuration? Please share as much detail as you can.
3) What is the signal path for AIR on the CI, compared to AES/EBU and USB? Or in other words, is there an optimum way to feed and Expert Pro with respect to ultimate performance / sound quality?
4) Are there any technical reasons why the beta and latest versions of the firmware can influence sound quality? Have any changes to the beta and latest versions of the firmware been specifically intended to improve sound quality performance?
5) With respect to the master companion link, are there any plans for to implement an alternative link method? For example, Dante or Ravenna protocol, or are any other options like Ethernet being considered? (To mitigate issues such as XLR cable length).
6) Are there any plans to increase playback resolution (or is the Pro-CI or Phantom physically capable of):
• Present - PCM to 24-bit/192 kHz and DoP / DSD64
• Future - PCM to 32bit/768kHz and DoP to DSD512, Native DSD to DSD512?
• Or anything above 192/DSD64?
7) What is the input impedance of the MM phono input? Has this been changed since Stereophile measured 14K on the D-Premier?
8) Is it technically possible to increase the power output of the 250Pro? Similarly, is there any scope for power increases for the 220, 440 & 1000 Pro models?
Legacy Expert Models:
9) What is the future for the “non-Pro” Expert models? What happened to the twice yearly firmware updates that were meant to make the EVO platform unique in its ability to constantly evolve and remove obsolescence? The computational power of the Expert range in use was specified as only 20% utilized from the fw10. This means that there is room for software improvements also in the old range. If not been abandoned completely, what can “legacy Expert” owners expect in the future?
10) Will the upgrade program restart? If so, when?
Phantom questions:
11) Is it possible to have a switch in Spark that selects "normal", "zero latency" or "time-coincident" for Phantom?
12) Any plans to include Phantoms in the RoonReady program after the Experts are certified?
Communication
13) Is the infamous pledge to make a better communication area on the website for engaging with customers still a reality? The Infinity Core log seemed to fade, with limited Devialet posting, and nothing for the latest final release software. Can they reconsider engaging with Devialetchat?
