Guys I am kind of new to this hobby and currently have Philips 9500, HD600, Sony 7506 and just bought DT770 80ohm version. From what I read 80ohm has the deepest and most slamming bass, so I bought it. All my headphones have been burnt in 100hrs with Pan Sonic album. I am using Schiit Magni 2 amp out of my custom built PC soundcard (Realtek ALC889) as DAC. the sound is great. I don't like the toght clamp of the 770's compared to others, if I keep them I need to stratch them somehow if its possible, I know its a metal band.
The biggest issue I have with these DT770, same as I had with HD598 that I returned is that on some heavy and deep bass songs like J Cole - Nobody's Perfect and Akon - Soul Survivor when I have it 75% out of Schiit at low gain the bass is great, its deep, its impact-full, nice sound stage and all but 50sec into the song when bass is deeper it feels like 770s cannot separate vocals and bass and vocals become a bit robotic, speaking through the fan kind, if I can describe them as such, if I lower the volume its better, but when they break up the volume is not too loud, if I keep the volume and switch to less sensitive Sony 7506 the sound is a bit louder even than 770 and even more bass, 7506 reproduces bass very good and not boomy and just tight, but the vocals sound perfect now playing even louder than 770s?! Seperation is perfect! Same goes for HD600 and 9500, but obviuosly those have much less bass through them. Same thing happened with HD598 that I returned as they had more bass than HD600 but it was more distorted and muddier I thought and on a bit higher volumes voice would break up on heavy bass songs.
Now playing Metalica, Dire Straits, Alisson Kraus, Patricia Barber etc 770's have no issues and sound great.. Any thoughts or did anyone experience anything similar? I do not think its a bad driver or blown driver as so far I only noticed these issues on these two songs so far. If anyone of you have these songs and can test them on yours that would be a great test. Thank you all!
