not my experience - I was "lawyered" out of a technical response to another poster's question in an "impressions" thread on the technical grounds that I may not own the product - when I never impled the answer was specific to the product   as far I could tell a significant fraction of the...

26 gage for iem?   no one ever heard mechanical stiffness, microphonics from the wire weighting, tugging the iem in your ear?   or the silly flex catching dragging on clothes, sending vibrations up the wire?   might as well try one of the paralleled CAT 5 diy speaker cable formulas for...

I hoped you would find it more useful - at the very least it should show the methods needed to make repeatable, usable hearing discrimination's that can inform Psychoacoustics models at the level serious professional researchers fare currently engaged with   Quote:   again you do seem to...

didn't read the reference yet did you?  

actually "you're wrong, but I don't have to provide any reasoning" is pretty much antithetical to this forum, and so far you sound like you are arguing from your personal "authority" since you don't expand on your objections   a few of us have used DSP, written algorithms, implemented filters...

some equalizers distort phase - its helpful to understand the linear systems terms well and use them unambiguously   "minimum phase" linear systems have a fixed relation between frequency response slope and phase   use a minimum phase EQ with a system that has minimum phase frequency...

I don't know if this might help johncarm www.davidgriesinger.com/intermod.ppt   hmm linking weird/broken, but the top level is a great plce to start anyway   Slides from the AES convention in Banff on intermodulation distortion in loudspeakers and its relationship to "high definition" audio.

big touring Rock bands are another case - standing, playing in front of literally deafening speaker stacks everyone on stage has isolating iem with their own monitoring feeds from the mixing board - and those aren't what's being sent to the speakers, audience   and neither is what is used to...

Orchestras definitely have to provide ear protection per OSHA, EU workplace safety sandards

are you sure you are familiar with modern audio consumerism?   stories sell, bling sells, quality??

and it has been checked by real world application   digital analog signal theory is one of the most powerful and thoroughly tested applications of math to technology, with "real world results" - its always fun reading of how it can't work over internet DSL connection sending Mbaud of data in...

I've mentioned some "EQ" options a few times: http://www.head-fi.org/t/677809/the-stax-thread-iii/3225#post_10869915

there are a few published reports - but as far as I know not replicated, not generally accepted   Kunchur, Oohashi both claim it required a minute or so for their subjects to respond to some "conventionally ultrasonic" content   https://en.wikipedia.org/wiki/Hypersonic_effect   there...

long phono cartridge wiring could be problematic with moving magnet/moving iron cartridges also having audibly significant inductance   MM cartridges often spec an optimum load capacitance and actually use the LC peaking to hit the target response   again added/differing cable capacitance...

there's a lot known about the electronics, recording, playback from the EE, "Signals and Systems" perspective - only a little bit of the Psychoacoustic limits are needed to determine that the objective, technical performance of many analog audio electronics are better than relevant demonstrated...
