Yes, you sure can. You understand that the JRC2114D's and the LME49720NA is the stock configuration right?

As LME49720NA is exactly the same chip as the LM4562NA.

Yes I understand what you are saying... I am thinking of replacing the STOCK JRC2114Ds with the new LME49720NAs and inserting one JRC2114D in the buffer spot so it would replace the stock LM4562NA. Basically the RCA output would be like this: 2 X LME49720NA (I/V) + JRC2114D (buffer). I dunno which person did this because I read it on the forum and said it was a nice setup. I would've gone for the LM6172IN for the buffer opamp but I can't get my hand on any of those here in audio ****hole Romania...

LE: Here it is.

LM4562 has bright warmer sound, harsh in the high and lack of bass.
while LME49720HA has a serious vocal laid back compare to LME49720NA which has slightly laid back on vocal only.
49720 is better for movie because of its better 2D sound but it is worse for certain music because of its unnatural high and sound fake for some instruments.
 
I prefer 3 opa2111kp in the xonar although it has some mixed up above the middle-high.
Some of the opamp cannot pair with LM4562, it will filter out the bass. I'm not sure whether because of its own LM4562 low bass characteristic or different soundstage between I/V and buffer opamp.

Well i believe this opamp really is a opinion thing. I dont find the 720HA to be lacking in the vocal at all.

with headphone? I tried with my cheap philips SHP2500 and the laid back not so serious.
720HA and NA have obvious laid back with my modified altec lansing mx5021, klipsch pro-media gmx a 2.1, logitech z5500 and sony hometheater. hopefully mine isnt degraded batch.

Most likely because it's oscillating like hell, I've heard LM4562MA in the new Firestone Spitfire...I still don't like it, but it's very bassy and not harsh at all. Quite honestly, I'd stay far away from the 4562/49720 as I/V on the STX.

i'm using 720HA in the buffer and i'm too experiencing somewhat laid-back vocals with headphones. i actually prefer it that way, i don't like vocals to stick out and mask the nearby freq. spectrum (it depends on recordings too, some recordings have vocals accentuated to the point where they sound raspy and unnatural). 
 
720HA has a balanced midrange presentation imo, at least through my amp and headphones.i noticed a small and narrow dip at about 500Hz with headphones and pretty much no dips with my speakers. but again, my speakers are far from neutral. it depends on so many factors that it is very hard to objectively describe a sound character of an op-amp. such description is often valid only for people with same or very similar gears.

I am using my MTPC to get the impression. But also pairing it with MX5021 too! But i have to say mx5021 is not a very good speaker to begin with, it has laid back vocal by the speaker itself. I need to up the treble to 4.5 lights to sound normal. One thing for sure is, Essence ST > cowon i9 + Fiio E5

I just installed my Essence STX last night. After playing with the drivers for a bit, something awesome happened. I was playing music and turned on the Dolby Headphone setting, and suddenly it felt like I wasn't wearing headphones anymore and the music was coming from the whole room. I had to take my headphones off to make sure I wasn't crazy! Just an awesome, massive soundstage.

Amazing quality, haven't found a single complaint about this card yet.
