Knopfy:
I just read the English translation of the Press Release and find it confused by the repeated use of the word "filigree". Using a word that refers to fine metallic decoration makes no sense in these instances........hence, we have NO idea of what is meant to be conveyed:
"It took an incredible effort by beyerdynamic's engineers to achieve those objectives using the extra-light 600-Ohm coils that the company prefers for their lightness yet perfect sound fidelity. Traditional extra-filigree drives tend to suffer from low efficiency rates. That prevents them from achieving real loudness when faced with underpowered headphone outputs, especially the popular 32 Ohm headphones that have become common in this age of the MP3. Yet the engineers didn't completely re-develop the driver just to increase its efficiency. They also achieved higher maximum volumes compared with previous 600 Ohm models – an impressive 7 decibels." .....filigree is also used in paragraph three and makes no sense.
Furthermore, just to be sure (this first reference from paragraph Two) "......features newly redesigned transducers that can produce an extremely high drive power of over one Tesla—making them the new top model at Heilbronn-based audio specialists beyerdynamic. That is roughly double the strength of normal headphone transducer systems. " Does this mean simply the ability to play louder at a given setting, ......or is this a reference to overall dynamic ability?
A question - when will Beyerdynamic act sensibly (and stop shooting themselves in the foot) by making the Gen. Leather Headband Covers, and Gen. Leather (with perforated backs) dt770 Earpads available as ordinary replacement parts instead of the nonsense of verifying and limiting their sale to specific prior Manufaktur purchases? This policy does NOT encourage further Manufaktur purchases and drives owners to aftermarket manufacturers.......which results in lost sales revenues to Beyerdynamic. I luv Beyer headphones - but, Beyerdynamic insists on doing things to their own detriment.
