So I have use my headphones primarily for gaming and music supplied by my desktop computer. I currently have a Soundblaster ZXR soundcard and running to an my darkvoice 336se amp. I just got a new Klipsch Heritage Amp and I was wondering if running a 3.5 cable to the Y splitter to allow me to have both amps plugged in at the same time would degrade the sound quality. The reason I want to do this is because I don't want to have to unplug one amp then plug in a new one when I want a different sound. It sound silly/lazy to do this but the way my layout is makes it annoying. Obviously I wouldn't have both amps on at the same time, just the one I'm currently listening to. Also as a side question, the Klipsch Heritage has a built in Dac. When I run the Klipsch Heritage plugged in with usb to the computer the sound is much thinner and seems less full than when I use the sound card as my dac. Is the soundblaster just a better dac or could there be other factors involved? It also seems to be the same case with a much cheaper Aune T1 amp/dac I have. Running it in usb with the Aune T1 acting as the amp/dac from my pc has the audio sounding much less full than if I use the soundblaster. Any help would greatly be appreciated. Thank you in advance, and if this isn't the right place for this post please let me know and I will repost in the proper forum.
