I have just received mine, and I can say the sound is very good!!
But it really tire my ears..I think it is to harsh and grainy.
Well I would love to mod then ( everything its possible), anybody could give me a hand on what could I change? or where to start?
i found it grainy & harsh too at 1st but it did calm down significantly after a few days of cooking - prolly atleast 100hrs or so. so just keep it playing no matter & it gets much better. as far as modding goes, there are other gurus here that can chime in. i only recently changed the output coupling caps & am also using a battery as power source. i found the battery gave a darker background & a slight expanded soundstage. the film caps gave it an even larger soundstage. goodluck & go for it. its seriouly fun & theres no beating the rush from the 1st mod! goodstuff!!
TDA1543 +--Cap-- - RCA-Output
I tested using RMAA.
From left to right.
Film Capacitors 4.7uF, Nichicon MUSE-ES 10uF (BP), Nichicon KW 33uF, Nichicon FG 10uF
CEC CD3300R play the test signal, MINI DAC in the DA conversion.
CEC CD3300R - COAX -> MINI DAC - RCA -> EDIROL UA-3FX -> WindowsPC (RMAA)
thxs for the freq response graph IIZUKA. so the slight attenuation of bass slam isnt just a figment of my imagination. luckily i dont have bass lite cans in either the HD650 or HE5-LEs so it actually ballances the sound pretty well. i also use vintage amps to drive my cans & all of them have hardware tone controlls to boost bass & treble at the very least. sometime i even like using the 'loudness' control for full impact on r&b/techno genres. LOL. strangely i find the tone controls or even the loudness do not affect the over sound quality except boosting the affected freqs.
i woulda matched the original 10uf if i could find any that fitted & these were the only ones at the EE store that even came close. as it is, it just makes it after some funny wire hookup routing. i must say that these caps do bring an "organic" feel to the sound & the much enlarged soundstage is most endearing. however i do hear some vocal sibilancessssss (& its only on vocals) that i didnt when stock but only on the HE5-LE as the smoother & less resolving HD650 glosses over it.
but its still early days yet & the sound mite still change some as the caps burn-in.
