Well there are a few decent sound cards out there. If analogue is a must for you and you’re on a budget then maybe the Corsair Vengeance 1300 & Asus Xonar DGX would suit you. Which you should be able to get all tolled for about $140.
What I currently have is a Razer Megaladon 7.1 USB headset.
I freakin love these puppies (laptop user). Uber comfortable for long sessions, and I wear glasses too. I only really feel a little discomfort from the glasses after about 5 hours. Five minute break and it’s good to go again.
Game sound is fantastic (I don’t use the 7.1 emulation much as I’ve found cuts a lot of the body of the sound out - though it does work well), midrange is probably the warmest most clearly punctuated area of it’s soundscape. And the volume scales well - these headphones go really LOUD, but still preserve a ton of detail.
Bass is imho purrrfect for music with the standard fabric ear cushions (I have the bass level set to maximum) and I wouldn’t even consider getting the leather replacements.
I listen to the DJ Channel on TRANS-FM most of the time. Sometimes the delivery of more subtle ques in the tracks sounds so real that I actually go “Wtf was that!?” pull off the headphones, look at the door to my room and continue, “oh yeah, it’s the headset.”
