Hello, I am your typical newbie who does not know much about amps in general. So I have researching, asking questions, etc... on here and other forums for advice. So here is my dilemma: I currently have a pair of DT-990s 250 Ohm Pro that I use for gaming/movies. Now I am interested in pairing them with an amp (since the SoundBlaster Z is not strong enough to run them for my standards). I have read that they pair best with tube amps, and a couple of my choices are the Schiit Vali & Schiit Valhalla. I have read that the Vali has some technical issues but the Valhalla receives rave reviews. I emailed Schiit and they stated they will drive the DT-990s very well. Unfortunately, they are quite expensive for me. I am also interested in purchasing another pair of headphones for orchestra music and for when I need to hear relaxing sounds (the DT-990s are fun but sometimes I can use a break from their intense sounds). The AKG series of headphones look appealing because their description sounds like what I am looking for in a pair for orchestra music, and their headphones look comfortable for bald/shaved heads (except the Q701). Particularly, the AKG k712 are very interesting to me at the moment. They look to be the most comfortable of the AKGs, which is very important to me, and their SQ is said to be better than the other K7xx and Q7xx series headphones. However, like the Valhalla, they are quite expensive. A representative of Schiit also stated that the Valhalla will not drive these as well as the DT-990s. So, in my situation, what would you do with a limited budget: Buy the Valhalla, and save $$$ for several months/sell stuff online until I can afford the AKG k712, or buy a cheaper amp and get the AKG k712 much sooner? There are not very many tube amps made in the USA around my price range, and I am not sure if I want to risk buying a cheaper tube amp without great customer service. Buying the Vali may be the best choice but with all the technical issues I have read about it online and its shorter warranty (2 years vs 5 years for other amps), I would be a bit worried if I bought it. I could buy a SS amp but tube amps are recommended for the DT-990s to provide a more warmer sound and reduce the harshness of the sibilance. Thank you.
