Upgrade details

[RebelMan]

Whether you consider it innovation or optimization is just a matter of definition. I would say that having a three-year old product that has, or will be, upgraded twice is innovative, absolutely. Cost of the upgrade completely aside, I can't think of any other company that has produced a line of products that are all upgradeable. Ask Von Schweikert or Sonore or JL Audio if they will be offering upgrades for their past products in three years.

Even if it is 'only' design optimization, that too represents years of design and prototypes and testing; remarkable especially for a company that clearly has some organizational challenges. And yes, communication clarity is not among their strengths. 

And finally, I'd say that the Devialet has clearly inspired imitation (or any term of flattery) products. Again, more so than any other audio product I can think of. No doubt many of these products are excellent, but without a doubt, they are following in the path cleared by Devialet. Sounds and looks and feels and smells like innovation to me.

But to the upgrade details (thread topic), I am interested and curious, certainly, but I bought a D120 rather than a D200, because the extra cost did not buy anything I needed or wanted- sound quality included. So I'll be interested to see what falls out when they shake the upgrade tree, but like Womaz and others, I'm still in love with the sound I have.

I concur, especially with the final point made regarding the D120.  Although I suspected you were referring to the firmware updates as one of the upgrades, strictly speaking of hardware upgrades, it appears that the D-Premier was eligible in 2013.  That being the case two hardware upgrades would also have suited your point regarding the 3 year time frame.
