1000+ Head-Fier
Each HD 800 has a unique serial number, each one has a slightly unique frequency response. There is baseline response all HD 800s need to meet, however they all vary slightly from it. Some people have noticed a difference between different ones.
In addition, apparently the early HD 800s sounded slightly different from the ones made currently. I'm sure someone else can expand on this...
How could that be?
Can anyone tell me anything about the 29xxx serial?
dunno with the 800's but i know it's true from experience with 3 different hd800 pairs
. it is also true fro some other cans. the mfgs are reluctant to call small improvement (which might be a minor "fix") to attention is what happens in some cases. so they deny it when asked.
