I am curious now to get to the bottom of this .. has Sennheiser been contacted and asked to comment about this "problem", in their premium product, at any time? Any links to any discussion beyond just user impressions and conjecture?

Trouble is, there can be, as a way of simplifying the concept, two types of problems: obviously audible effects, little glitchy noise, buzzes, etc; or, that the sound just "doesn't sound right". Both are distortion, both could be measurable, but they are at different levels of intensity. One is easy to point the finger at and say, there it is!; the other just gives you a headache over some time, makes the sound dull, fatiguing - far harder to say in that case there's a problem with the build quality, far easier to claim that it's just "bad recordings" ...

i'm sure they have, they have a booth at RMAF and CANJAM every year. they arent going to change the tooling to suit the people who usually dont have the product any more.

very predictable of you, yeah conjecture, i'm sure Tyll would be happy with you labelling the several page technical article he wrote about a headphone hes owned for years, sold for years and his ability to interpret measurements made on a high end analyzer... conjecture. hes probably measured more headphones than sennhieser

measurements of stock, measurements with the damping removed altogether and measurements of various other damping materials and their effects, both positive and negative of a resonance in a specific frequency band around 6.5khz.

you can only be trolling, so i'm reporting you. feel free to argue that you simply dont understand the words and pictures so well. So quickly the love affair fades with the words you wield....

directly above this post you seem to be arguing my point again.... are you taking it in turns with someone else?

Some dear friends have been promising me a birthday party. It looks like as if, by the time it happens, I will be taken to be a Piscean. Or --- OMG Aries???

To be precise, the Tannerin. Named after - guess who? Similar sound and circuit, different technique. We've been trying to build one at work as the Theremin and all the hand waving had gotten tiresome.

glad you picked up on it it was a partial reminder to myself as well. thats sad news alright, I love a good Theremin, a friend of mine made himself a midi Theremin, one of the most bizarre instruments ever, taken to a whole new level of weird.

I thought it was "Dr. Lube"

One learns something new every day (if one is fortunate).

The obit suggested the Theremin so I leapt to that conclusion. And some other BB apochrypha evidently makes the same assumption.
