I'm about ready to order some etys for use strictly with an amp, yet for some reason I'm thinking about the 4Bs
The Etymotic graph shows about a 5db drop in the 4S 10khz response. It doesn't make sense to me that a difference of 5 db would make the 4Bs so bright as to be unconsidered for well made stereo recordings.
I read the claims of audio studies that suggest a 4-10db boost in high-end response of recordings is needed to off set normal room colorations, and that:
"The ER-4S has been designed with a gradual rolloff in the high frequencies and is well suited for all types of stereo recording reproduction. "
All types of recordings? Alot of popular recordings are loud, compressed, and processed in the upper regions from what I've heard, so yes, you would probably want a roll-off if you listen to lousy recordings. But what if you listen to primarily, newer jazz and classical recordings -- Do engineers really boost the highs for this type of muisc? hmm
For the hell of it, I took my 7506s(which have pretty flat response) and played some test tones, sine sweeps, and what I believe to be well made CDs of mostly jazz music. I compared a flat response on Winamp to an approx. 5db. drop at 12kHz. To me, I thought the flatter response sounded better and more real.
Any one compared the 4B vs. 4S.?
