Oldshoe99, I ask that YOU help the head-fi community.
Please present your testing gear and the tracks you chose to utilize for your conclusions. It would give people a chance to create some sort of reference and maybe put ourselves in a similar experience to better understand your specific subjective experience in your comparison.
I am not seeing many facts period, including from you.
Facts, being bits of information that have been proven to exist. Objective measures have a tendency to be facts for a particular sample set. Honestly, I am not entirely convinced the opinions of three people is enough of a sample size to deduce a solid conclusion, but the existence for a specific conclusion can be noted.
If you remember WAY back in this thread, baka made some OBJECTIVE observations on the driver assembly of the 940 and 840, and pointed out (while providing images) many similarities between the driver structures. He also noted that the enclosures behind the drivers seemed to be packed inconsistently. Is it unreasonable to assume that this inconsistency could lead to some acoustical impacts?
Baka also inferred the possibility (and I tread carefully here, Baka only pointed it out as a possibility and not an errorhoneous conclusion) that maybe Shure utilizes a similar technique as Grado, where the same drivers are used between the models, but the ones that measure better (first chance at potential variation in end result sonics) are put into the better model and then voiced or tuned different (another chance for variation).
Between the inconsistent enclosure and the possibility of re-tuning drivers that already measure with some variation is it unreasonable to think all these (at times massive) differences of opinion are a result of an actual quality control problem? That models that are being released ARE indeed inconsistent and have variation that is large enough for our ears to indeed detect? Have these problems been noted in Grados lines?
There was also that large recall and push back release date for the 940. Did some of the "old" 940s hit the market?
This is ALL A MENTION OF POSSIBILITY. I am not saying anything indefinitely, just giving a simple underhanded toss to a possible reason as to why opinions vary so much on this particular headphone.
The headphone could even be really picky with sources and amps, this hasn't hardly been addressed.
Accuse me of beating the dead horse, but there are just WAY too many variables to make a lot of blanket statements.
Oldshoe99, if you could share your gear with us it might HELP US to understand the root of your subjective experience with the HD800 and SRH940 and compare it to others. Is this not the type of information that could prove helpful? Or am I not worth your time because I ask questions and don't provide facts?
