What are the consequences for not upgrading to pro?

[blair.athol]

I went for the Pro purely on the basis of what it offered with respect to improved sound quality.  If the streamer board or any currently unknown features prove to be useful to me in the future, this will be a bonus.  It has to be said that the relative cost of going Pro from a D800 is a lot lower than from a D200, so a very careful audition or home evaluation would be required to establish if sound quality alone is worth the money.  

Personally, I would not upgrade based on the promise of as yet unknown future features, I would upgrade based only on what is available and verifiable now.  In effect you have the option to upgrade at any time.  Why not wait a year?  Sit back and enjoy the D200.  If at some time in the future there is some new feature on the Pro that you feel you would like, sell or PX your D200 for a new or second-hand Pro, get the best deal you can.  This would most likely cost no more than the upgrade now, and at least you would be spending your cash knowing for certain what you are getting.

I tend to agree here. 

Devialet themselves just told me that the Devialet OS is currently intended for DLNA and Phantom compatibility. Anything else is currently not known and therefore also not clear in how far it will be applicablt to the "non-pro" devices.

The only disadvantage for upgrading next year is their "free Devialet OS card" saving me 1800€ if ordering the upgrade this year. Given however the currently intended features of the Devialet OS card, I can live with that. + if they offer it for free this year, I do not see y it keeps them from offering it for free next year. I mean silicone gets cheaper and not more expensive with time...

+1 from my point of sound.
As long as I have no opportunity for an in depth sound comparison (my dealer in Frankfurt has no information when to receive the first Pros although being one of the major High End stores in Germany), I will not consider to upgrade. For sure DNLA is not an argument for me at all. Air works perfectly in my setup and DNLA is not easily supported by my Mac as streaming source. I had tested it previosly an was not impressed.
