Please can I have a link or directions to the chart shown in thread [Review] InEar Stage Diver 3 - An experience - Page 49 Post 729.
Do you mean this?
Finally the Stage diver series is starting to spread to more ears. Joker has added both to his list, the SD2 and SD3 and ranks them highly. I do not have that much experience with iem`s but enough to know the SD3 is in a different league to the W4 in terms of quantity, impact and soundstage. I classed the SD3 more of an over ear rather than an iem in my findings/review.. My pair really have a wow factor now, zero sibilance and cannot make them distort. Serious performers.
The Ortofon tips are a revelation too. They help in exposing the whole sound spectrum with their open design/exit compared to the stock small outlet tips. Another advantage of these tips that I have found is that there seems to be less pressure created in your ear.
Listening last night after a fews days off and straight out of an Ipod they sounded excellent but showed they do really need amping. As my FiiO Alpen had run out of juice I had no option to listen straight out but the SD3 clearly benefits from a good amp/lod, they need a kick up the a*s*.
Bottom line - glad they are getting some exposure now, they more than deserve it.
The human ear is not a machine, meaning heard tones and loudness are not absolute. The human brain always compares in relation.
Even IF there is something like burn-in, the likelihood of not noticing it is extremely high, due to your brain adjusting and masking smallest details. This procedure will most likely happen every time but becomes smaller the more often your expectancy becomes closer to what you will perceive. This is HIGHLY subjective and can be anywhere from one second to hundred years. YMMV
I agree with Ultrazino`s post above which is mostly brain burn but I also believe that any electronic signal needs "bedding in" but there is not very much to back that up and certainly do not want to get into a debate!
I am more a believer of synergy, especially where portable devices are concerned i.e Ipod/LOD/AMP. This makes sense as the signal is being diverted through another circuit in the loop. With hifi this is source direct where you bypass the amp circuit but unless your portable amp has bypass circuit (bass boosts etc would not work) then you are modding the signal to a point.
Anyway... I would seriously advise an audition of either of these (only SD3 I have) and not only that try and get to listen to the SD3 amped too so you can A/B.
Happy new year.
Edit: Posting again the Ortofon? tip for reference.
