upgrade is back

[RebelMan]

Regarding the upgrade, I disagree with the above statement by @RebelMan regarding sound quality. 

That's okay, but the sobering truth is it just doesn't matter.  There is no disputing that the Pro series has seen an improvement over the previous generation but unless you have a near perfect environment from which to listen the infinitesimal benefits to sound quality are inconsequential.  

From the outset the Devialet engineers were tasked with only two key criteria when developing the brand's image.  The first was to produce a product that approaches, closer than what has ever been realized before, the "theoretically" ideal amplified signal.  The second was to produce a product that was capable of producing 1000 watts in a pizza-sized box.  Unorthodoxically, Devialet has refused to voice (tune) their product by ear.  In fact, they do not even employ a listening room for that purpose.  Instead they have let the principles of science be their only guide.

Since the engineers had already achieved their first goal, with the introduction of the D-Premier, in their minds, they didn't set out to produce a better sounding product with the Pro series. They did, however, set out to make it far more efficient in an effort to achieve their second goal, which again in their minds they had succeeded in doing with the introduction of the Expert 1000 Pro.

Regardless of anyone's stature in society the cost benefit to upgrade from the 120 to the 140 Pro on the basis of sound quality alone is misguided thinking at best and delusional at worst.  Anyone that undertakes the task to upgrade for sound's sake alone will be kidding themselves and will eventually be left wanting or sorely disappointed.  The 120 is already that good (sounding) it's just not as capable.   Keep in mind these comments come from someone that has a technical background and the resources to own a Devialet Expert 1000 Pro.

As has already been mentioned, one will be far better served using their upgrade funds elsewhere in their system if they are simply looking to improve sound quality.
