The very rare headphones in Russia Amfiton TDS-H25S. 

Everything is fitted into the original box.

Mod.   Elna Silmic 2 + Wima FKP-2. 4.7UF was used Panasonic BP. It sounds much better now.

wualta, I do not know how to put the sound in English. Lets i send you a pair of TDS 16. You will write something about it. I need your adress in private.

Faust2D, 3 pairs.

TDS 16 "Эхо".

Faust2D, Do not be cruel.

Faust2D, Do you have an old T-50? What is the difference?

fixt, I have many headphones but Denon 1001 (Creative Live) sounds very good. I like them.

QQQ, о.к. I will not write here.

As for first post. QQQ, Ah, no problem. I help you to understand: K601 has such frequency response. K701 has a little more of bass. It is very good. Why do you want to change it? Do you have any ideas to do k701 а little better? How to change total harmonic distortion? Аh?

It is a strange mod. K701....no need to improve the sound.

For information. Denon D1001 has the same drivers as Creative Aurvana Live! The drivers are made by Foster. Creative is cheeper....

Faust2D, I have the same version of T50RP. I think it is an ordinary version. Did you remove native damper? Fostex T-50RP has quite enough of mid-bass but not much of lower bass. Moreover T 50RP is not very detailed cans because of the pit in the upper mid-range. In general, it is an...

foreverzer0, I use STD and PK series. STD 16V 10uf STD 50V 220uf (as a power cap and headphones out) PK 25V 47uf 2*LM4562+ad8066 just a good variant.

GuyMe, There are two graphics of tds 5m in "The USSR" but they are not correct because that headphones was very old. The frequency response of the new tds 5m (from the box):

I modded my E-MU0404Usb-LM4562MA-line out, LM4562MA+AD8066AR-headphones out. All the caps are Black Gates. The sound card sounds much more interesting: rich, detailed, not so sharp as it was. Bass response became much better. Thanks to foreverzer0.

There is no any difference in hearing (according to the article).

I got a pair of Yamaha HP-3. The drivers of the headphones are small. There is a few of low-bass but mid-bass is more than enough. HP-3 sounds like «analog»: not very detailed, soft sound with good general macrodynamics. It is very good for old hard rock, for example Deep Purple, Black Sabbath...

K601 is better for me than K701-it is too bright.

Sansui SS-100 looks great! Frequency responce is very good too. It seems to me it is one of the best orthodynamic headphones.
