essence stx - opa2107's I/V, LME49720HA buffer. is this good match for buffer?

[dlb0089]

so, ive got an essence stx with opa2107's in I/V, and a 49720HA in buffer currently. i'm wondering from an electronics standpoint mostly, is this a good combo? ive been listening for awhile and it sounds pretty good mostly, but i'm wondering what other buffer combinations you guys/gals have tried with the 2107's in I/V, or Burr Browns in I/V in general.

my collection currently consists of a few 49720HAs, a lme4562, and the 2 stock jrc2114's. at some point in the future i'd like to try out some opa2227's in I/V, but while i'm trying out the 2107's i'd like to experiment with buffer a bit. i've experienced the difference I/V changed can make, but i've yet to see how buffer affects sound much.

thanks alot folks!

The 2107's are really good opamps for audio and they make excellent converters.
You might want to post these questions in the STX threads as there are many that post in there that have tested with many opamps. Thre is also a opamp thread where peopel post impression based on their own testing. Great place to get ideas about what to try...etc

To note, the buffer only affects the sound for the line outs if your using headphones the buffer is not in the circuit at all.
Based on the testing I have done with the three opamp configuration, the I/V modify the sound the most and the buffers can be used to....enhance or hinder certain aspects fo the sound.
for example, your I/V opamps have great bass..mids..etc but their high range is a bit much for your gear. Use an opamp in the buffer that has a warmer sound and rolls off the highs. This combination should give you amost of the aspects of the I/V and roll of the highs for you. This is a simple explanation but that has been the way it has worked for me, more or less. You can get some really good combinations if you consider all three opamps in the equation.
Hope that helps.
