Hello everyone, first time poster here! I've had the Essence STX for a long time now and I am not satisfied with the sound I'm getting through my HD595's. It's decent, but I feel like it could be better. The bass feels lacking and muddled while the highs seem too harsh. I had a very ghetto setup dedicated to my headphones, including an old Sony receiver and it seemed a bit better. That being said, I am content with what I'm getting out of my speakers but there's always room for improvement! Can someone please recommend some Op Amps that are best matched with my setup? Thanks a ton!
Xonar Essence STX --> custom RCA cables -> NAD C730 Stereo Receiver -> Polk TSi 500 towers and Polk 8" sub
--> Sennheiser HD 595 w/ soundstage mod
LME49720 are a low cost (under $10) way of improving the Essence STX's audio quality.
I use three AD797BRs op-amps in my STX, LME49990 have gotten good reviews.
both cost around $50 for three.
Technically with the LME49990 and AD797BRs you need to use 6 op-amps (cost $50) as they have to be added in pairs to the three DIP-8 slots on the STX
Have you compared the audio quality of the HD595 plugged into the Essence STX and the NAD?
Did you disable the motherboard's on-board audio when you installed the Essence STX?
