You know it's strange because I usually find a boosted 6k-7k area quite harsh as well.
Yet for some weird reason the ToneKing T4 isn't sibilant at all.
Really my big fear with the T800 is that 3.5k bump will be way beyond my tolerances.
According to the graphs I've seen it's like 13db higher than the mids...
13db? Ouch!!
I guess I'll have to EQ it out, but can I pull it down enough without screwing with the signature too much??
Because I'm thinking at least -8db.
Early this year I purchased Toneking T4 from a friend, and that peak above 6 Khz made for a harsh treble, sometimes inducing me headaches; so not so much joy for me with T4. After a while, I gave up and decided to place it for sale, to help to finance a new IEM. Well, fortunately, inspired by audioreview.org´s modding 101 tips, a few days back decided to try to tame the beast by covering the nozzles with a piece of tea bag I had at hand.
Voila!!! I am so glad I did try it, that simple mod works for my ears, no more harsh treble, and now I can enjoy the fantastic clear midrange and a very linear and smooth transition from midrange to upper lows rendered by Toneking T4.
Switching from BGVP Dm6 to T4 feels like lifting a veil, showing a very transparent midrange, with fantastic vocals presentation.
Puzzled by Hawaiibadboy´s review on Toneking T4, I recently listened to some Led Zeppelin tracks (Kashmir, Over The Hills And Far Away, How Many More Times, Stairway To Heaven, etc.) and Robert Plant´s voice sounds upfront and crystal clear on T4, much more so than in DM6. Even tried some female vocals (London Grammar, Alison Moyet, St. Vincent, etc,) and all sound wonderful.
Either my T4 was tuned differently to Badboy´s or they belong to different versions.
The soundstage on T4 is intimate but the sound is so engaging that I really don’t care about soundstage on this set. Nevertheless, ambiance and reverberation info varies greatly from every recording.
Ah, bass on T4 is present when called upon, and the only thing I miss is the bass extension to the lowest octave from 20 to 40 Hz.
If T800 has a midrange as transparent as T4´s, bigger soundstage, and more powerful and extended bass, then T800 will be my next purchase. But no matter what, T4 is a keeper for me; more so than DM6
Sorry for sidetracking this fabulous thread, having so much fun reading about T800 and Sony M7, the 2 IEMs currently on my radar.
Exciting times in this Chifi world.
