I'm definitely going to purchase a pair of Beyerdynamic DT 990's, it's just a matter of which one to get. I'll be using these strictly for my desktop computer. The problem is, I only have an on-board soundcard. So there's no way it will be able to work the 600's or even 250's. However, I WILL be getting ASUS Xonar Essence STX card eventually (probably months down the line though), which can run up to 600 ohms.
I'm just wondering if I'll still be able to enjoy the 600's with my computer right now? Or will the volume be too low/not enough punch/etc? Even with volume maxed/using an equalizer?
IF it's basically unusable without an amp/sound card, how do the 250's fare?
Even if the 600's are a little weak, will it be worth it over the 250 in the end (once I get the soundcard)?
