Hello!
I also own an Xonar U7 DAC/AMP (classic edition) and i want to post here some of my impressions about this soundcard:
-very good upgrade from Realtek HD 898 (Carbon Based Lifeforms sounds a ton better now - big CBL fan here!
)
-my ROCCAT KAVE sound more defined,more bassy than before (i play BF4 online).
For music i have a pair of decent PHILIPS SHP 3000 cans and for gaming i use Roccat KAVE 5.1 headset. My OS is Windows 7 X64 SP1 and i have an desktop computer.
Despite the fact that i'm overall pleased with the quality of sound,i have few cons,though...
1) i heard some discrete white noise/harsh sometimes with DOLBY EQ on when i listen music,but when i switch off DOLBY that noise dissapear. The thing is that this ''noise'' is not present all the time,just to some melodys... I tested an audio file 24 bit/96 khz and sound is cristal and very pleasant with no interferences.
2) in BF4,when i set KAVE to 24 bit/192 khz/5.1 ch i hear a little cracklings/hiss noises sometimes in the end of the round and not at all when the match is activ. Also in movies i heard a few times some strange noises,but very very rare. Curious that this noise is not present anymore and everything is cristal clear if i use SHP 3000 with DOLBY vitualization set to max (sounds sick!).
The switch for USB 2.0 was ON by default (factory) so i just leave it like that.
My guess is that Win 7 X64 drivers for U7 are pretty bad (i have an D1 PCI before and OMG!
). Also mic work flawless with no interferences. As far as i remember,D1 act the same way like described in 2).
I like to hear some opinions about this 2 ''problems'' that i encountered with my U7. Please forgive my english,is not my native language.
Thanks for your opinions!
