REVIEW: Fischer Audio FA-011 - OFF THE DEEP END!! - Page 136

Im using an Fiio E10 with the bass boost set to on with certain songs... what can i say i like to feel my bass :-) im still blown away how much difference the pads made to sound quality... I am enjoying them quite a lot, maybe later today ill recompare them to my other two, pretty sure ill like them more then the grado sr80s now.

I do find them brighter than my Grados, but much less mid-centric.  I use a 75-ohm impedance adaptor to tame the highs just a bit.  It may be because I listen to mostly metal though.  Oh, and mine are the original dark red wood with the coiled cable.  Although I've been drooling over the new look...

 

Impedance adapter???

I can't listen to my FA-011 anymore without an impedance adapter. I have bought 3 off ebay.

It takes the edge off the highs. My ears are sensitive to excessive (IMO) highs. BTW I have the original dark red ones with the coiled cable.

I bought this one, http://www.ebay.com/itm/290372905689  Same thing though.  I tried a 75ohm and a 120ohm.  The 120ohm was too much.

 

I like sparkly highs, but there's just a touch too much on these FA-011's for me.  I can listen to them w/o the adapter, but I prefer not to.

Hmm... And why this instead of EQ?

Some of my sources don't have adequate EQ (CD Player, Pandora, Soundcloud)

Not sure if there is any real technical reason, but I did it because I didn't want to keep fiddling with the EQ, and also as an experiment to see what it did to the sound.

ive fiddled with software EQs a lot, and it seems like the entire sound quality is diminished when i do so even though i am able to fix one part of the frequency the overall affect is generally negative.

I'm in way over my head here, but I think a filter like this should be much more destructive to the sound wave forms than a digital filter. Need some engineer geeks to weigh in here. I know back in analog days, the general goal was to have as little filtering as possible.

I don't think a resistor adaptor can be considered a filter as such. It will affect the impedance as seen by the [power] source (amplifier in this case) and therefore will affect the way the headphones behave, most notably probably the damping factor.

I'm not an engineer, however I am a student doing an EE degree... that said I can't say I totally connect the material in the classroom to the world of headphones, at least yet.

You actually pretty much nailed it. The damping factor will cause anomaly behaviour with the treble and highs mainly. One thing I'm trying to experiment is by increasing these to 600ohm's driven from a source with adequate power it should tame the highs a bit and bring the treble out slightly making it controlled. I can't find 600ohm resistors though.

Hey, cool! very happy about that :-)


 

Would 600 Ohms increase the voltage requirement tremendously?

 

Another thing I don't get is the mix between electrical damping and mechanical damping: I'm guessing the phones are designed in a way those two work together and by altering the electrical damping factor wouldn't you possibly get into a situation where they interfere with each other?

 

Also wanted to ask: for the peeps that changed the pads to HiFiMan pads - how do you secure them? I find that they fall of really easily....

600ohm wouldn't increase the current needed by a large amount, but it'd definitely put the 011 into the category of using a good desktop amp to drive them to do it justice. 

 

I'm guessing you're referring mechanical dampening to things such as baffle, dynamat dampening made to the interior of the driver housing and drivers itself to adjust change in sound?
