I received the following email yesterday from Devialet about the end of the possibility of upgrading an Expert unit to an Expert Pro unit:
The Expert Pro upgrade is is a major hardware and software Upgrade pushing the boundaries of audiophile pleasure, improving performance at all power levels.
- New motherboard with all Devialet key-technology components.
- New Class-A amp.
- New Magic WireŽ (Digital-Analog conversion).
- New power supply.
- New Class-D amp.
- New architecture, Devialet OS ready.
- New firmware.
- New Devialet OS board, which will be offered to you for free as soon as it is this year.
On 15th May 2017, the Expert Pro Upgrade will come to an end.
I bought a Devialet 120 approximately a month before the upgrade program was announced, and I'm a little annoyed to be asked for another ~$4,000 to upgrade the unit. An odd element of the upgrade is that, though the upgrade program ends May 15, the new digital board is not ready and will be provided later.
Do any members have a view about the improvement in moving from Expert to Expert Pro? I am, admittedly, skeptical, given my bad experiences with the AIR driver and the fact that the upgrade will include the new digital board at an undetermined time in the future.
