DT-1990 Pro 250 Ohm : After a bit of tuning one of the best :)

DT1990 are simply great for its price, but have some downsides too. As many here I own also DT990 so will compare.

DT1990 have unbelievable nice build quality - the example of precision German craftmanship. They looks nice, handles nice, sounds nice and the moment you take them to your hands you have that premium feeling worth of every euro spent on these. Many Hi-end headphones, even those twice as priced as these, can have poisonously pronounced treble to bring in the clarity and this is that case. On the other hand those heights are very very very detailed with very low distortion, what makes it incredibly precise and analytical while listening. You have 2 pad options in case which is really nice, but none of these perform to tame the treble peak. To tweak this to absolute precision, tame the hights and increase comfort even further I strongly recommend buying another branded Velour pads for these as I did. I have found on one review including measurements that one (not sure I can say other brand name here in review) specific pads remove the poisonous 8khz peak and it is very true! These headphones with aftermarket pads are simply incredible listening experience I have never experienced before. As I used new pads, I moved the DT1990 pads to my old DT990 and it improved them too! with black pads they looks very nice and sounds a bit better too :)

Both DT990 and DT1990 sounds very good, however when listening to song with rice shaker with DT990 I have troubles to indentify hi-hat or shaker or whats goin on in there. However with DT1990 I can very confidently and clearly identify the rice shaker and the amount of rice being shaked :) it is remarkable in identifying the details and you immedietely knows if track is mastered good or wrong because with so low distortion and clear details you hear the difference in mastering of the tracks so much, that you will hate the wrongly recorded songs. Btw I think they are even better for gaming!

The sound dampening or acoustic chamber in DT1990 is also MUCH better than DT990. Both are open phones, however when you put DT1990 on your head it better filters the space and noise floor around you, the best to describe this is like you sit in very nice sound dampened and quiet cinema room.

The amplifier is a must for these. I have tried many options, started with TPA6120 but they wanted more as the loud peaks were not as nice as I would like to, so I ended with WCF E88CC OTL and that was it! I cannot imagine anything better for listening as this combo...

They are very good headphones but require some tweaks to become absolute best. As mentioned the pads. Also the cable... its nice, looks quality, but smells! smells like chinese shoes :( Hope that smell will come off eventually but instead of two cables in box I would like one better braided cable or something, so I think I will change the cable later too.
