It certainly must be worth a try David , It does sound as though the opamps may be fried , perhaps the STX is on the way out . Examine the opamp sockets for damage when you swap out the opamps . If you don't have or can't loan any replacement opamps the cheapest route may be NE5532 , just to...- fredeb

Are you overclocking ? This could cause problems . Try updating the motherboard Bios ( even if you over-write with same version ) , bios could be corrupt .

The Xonar Essence STX Q/A, tweaking, impressions thread
From the first page of this thread : Q: What's the deal with interchangeable opamps? A: The card has 3 swappable 8-pin dual opamps. The two matched I/V opamps impact the headphone out alone, while the 3rd "buffer" opamp impacts the RCA out. If you are only using the headphone out you only have...- fredeb

I'd start with 1x LM6172IN in the buffer position and 2x OPA1612AID in the I/V section , and try all the rest in the I/V section and see which sound you prefer . We all have our own ears , and one man's meat is anothers poison . Play with them - there's a time and a place for everything . Try...- fredeb

Somehow I think 2x OPA1612 in the I/V section is what you're looking for if you want more dynamics , a more refined sound . Look at link provided two or three posts back .- fredeb

Why not use the headphones with the STX 2 first , for a while , that way you will at least appreciate the difference when changing opamps or using an external amplifier .
