Bonddam,

Do you set Chord Hugo TT2 as Dac or as Amp ?
I find it, if i set as Dac the volume on the WA33 to TC is already loud on 8 o'clock.

The TT2 as a dac. The highest I go is close to noon. On my setup it’s enjoyable at 8. My Empyrean is only enjoyable at higher volumes where TC has a full sound at all levels.

Thanks,
i can not do it as Dac as the volume on woo is to loud , and chord output is 5v on xlr.
Woo suggest to lower the output, so i set as amp and lower the volume.

I never have volume issues. Only headphone that has an issue is my Fostex 909 where anything past 8 is too loud.

Has anyone tried the ECP DSHA3F amp with the 1266?

Will not properly drive the 1266.

You will have to wait for the DSHA4F which is in limbo due to Doug's supplier issues. At that, you might want to investigate his Copenhagen as an alternative.

Just came back to the TC after a 3 week rotation with the diana phi and susvara, and the TC is still the king in terms of an overall hp. Enjoy everyone!

I feel that changing the earpads and arm position influence the bass and soundstage a lot, but not much for the brightness... I should say, it is sibilance for some instruments and some vocals bother me a lot(a lot of pain for my eardrum.....). I played Brahms and Beethoven violin concerto and the violin sounds perfect with no sibilance at all.

Except for this annoying issue, I would say I love everything about TC lol

Trying to figure it out now....
1. Anyone tried to DSP or EQ the 1266 phi TC? I'm thinking to -3db @ 9khz or 11khz
2. I saw a mod from https://www.superbestaudiofriends.org/index.php?threads/new-abyss-ab-1266-v2-incoming.4163/page-4


I'm very surprised that looks like I am the only one who has this issue...... Maybe something wrong with my system...? Surface pro6(fidilized)->mscaler->dave->formula s+powerman ...

Thanks guys!

I found the issue last night.... Surprisingly, The brightness / sibilant or hardness that I mentioned, actually from 1-1.5 khz..... ( ???? probably my ears need surgery) I found out by listening to the 500hz all the way to 20khz sine wave.

Simply EQ -3db, Q value 3, @ 1khz or 1.5khz, problem solved. Even some mp3 tracks are totally fine now.

I'm very happy and totally satisfied with the TC sound now : )

Nice you found a fix, it seems that it would make thr mids even more recessed

Abyss (both Phi and TC) have a marked peak around 1-1.5KHz:

Right, and based on the measurement from this forum: http://www.tellementnomade.org/forum/viewtopic.php?f=92&t=21753&start=930#p759802

(The measurement is Phi not TC)

and compare with the TC measurement you shared:

Maybe should EQ @1250hz, -3db, Q value 3 to be more precise.

The 1KHz peak was my biggest concern with these headphones, as it is found not in the harmonics, but in the register of many (if not most) acoustics instruments, and therefore it affects their timbre. I sold my Phi CC headphones some weeks ago, but I used to EQ the 1KHz peak with a -6dB point and also added a +3dB eq point around 5KHz, as I found those two spots as the most problematic.

My goal is to reduce the brightness without touching too much of the original sound... As you said, that would affect the timbre of the instrument...
1/2 Octave Bandwidth: Q = 2.871
1/3 Octave Bandwidth: Q = 4.36
1/4 Octave Bandwidth: Q = 5.76
1/8 Octave Bandwidth: Q = 11.54

maybe I have to find the exact note that caused the brightness, then increase the Q value, thus minimize the influence.

I would just apply a -4dB EQ point at 1KHz or 1.5KHz and tried different Q settings until you find your prefered sound. In my opinion, anything below 1.5KHz does not make a headphone sound more or less bright, it directly affects the timbre in a more obvious way, in the case of that peak I think it makes the instrument sound more nasal, it was very obvious to me specially with grand piano recordings. If you want to make it sound less bright then you need to EQ higher, somewhere in the 4-8KHz spectrum.

I got my new O-rings. I got a multipack of different sizes. The size right above the stock O-ring works perfectly. Everything fits like it did with the old headband.
