Ok, I have clarified the one thing that didn't make sense to me. For Concero HD:
V2.7
-Added Non-Volatile Filter settings.
-Correct the Volume control bug for Audio Class 1.0 for Full Speed.
-Updated USB descriptors to just Audio Class 1.0 for Full Speed, and Audio Class 2.0 for High Speed.
-Scale volume range from 0dB to -63.5dB (Used to be 0 to –127dB)
-Fixed a bug where clipping DSD signal caused audio dropouts
-Updated to support both ES9018K2M-W and ES9018K2M-V silicon (THD coefficients are updated)
-Allow pass data through SPDIF decoder when "Consumer mode" and "Data" and "176.4k"is set
-Allow SPDIF to be decoded even if the "DATA" flag is set.
For Concero HP (SPDIF input version):
V2.7
-Added Non-Volatile Filter settings.
-Correct the Volume control bug for Audio Class 1.0 for Full Speed
-Updated USB descriptors to just Audio Class 1.0 for Full Speed, and Audio Class 2.0 for High Speed
-Scale volume range from 0dB to -63.5dB (Used to be 0 to –127dB)
-Fixed a bug where clipping DSD signal caused audio dropouts
-Added USB initial volume level to be -40dB
-Updated to support both ES9018K2M-W and ES9018K2M-V silicon (THD coefficients are updated)
-Added Non_Volatile Volume settings for SPDIF input modes
-Change initial volume to be -40dB for SPDIF mode. (from -50dB)
-Allow pass data through SPDIF decoder when "Consumer mode" and "Data" and "176.4k"is set
-Allow SPDIF to be decoded even if the "DATA" flag is set.
-Made the SPDIF input volume be 0dB if not previously programmed, else it keep that last volume set.
-Updated the Rotary decoder for better CW/CCW detection
For Concero HP (SPDIF output version):
V2.7
-Added Non-Volatile Filter settings.
-Correct the Volume control bug for Audio Class 1.0 for Full Speed
-Updated USB descriptors to just Audio Class 1.0 for Full Speed, and Audio Class 2.0 for High Speed
-Scale volume range from 0dB to -63.5dB (Used to be 0 to –127dB)
-Fixed a bug where clipping DSD signal caused audio dropouts
-Added USB initial volume level to be -40dB
-Updated to support both ES9018K2M-W and ES9018K2M-V silicon (THD coefficients are updated)
-Updated the Rotary decoder for better CW/CCW detection
For original Concero:
V2.7
-Added Non-Volatile Filter settings.
-Updated USB descriptors to just Audio Class 1.0 for Full Speed, and Audio Class 2.0 for High Speed
-Improved SPDIF decoder to have less glitches with power supply spikes.
-Allow SPDIF to be decoded even if the "DATA" flag is set.
So as you can see, lots of little things. The main one that is most noticeable is the volume control on the HD and HP. It now covers a smaller range which means each "step" is more of a fine adjustment. The trade off on this is higher volume in general. Apparently they had people asking for this for more ease in dialing in exact levels.
Seeing as they increased the volume and all... Does it play better with Harder to drive headphones on the higher end of the volume control..?? Ive yet to actually try my HP with a pair of HD600's etc, so im wondering how it fairs now.
