Opamp Suggestion

post #1 of 5
Thread Starter 
Hello guys. I have an Audiotrak Prodigy ATM and opamp is changeable. Some say OPA2107AP is pretty good for its price but I thought I better ask you users first.
 
What do you suggest as an opamp? (dual and no more than $10 and I listen dubstep, rock and it's genres)

granted i have a hybrid amp so the tubes are influencing the sound as well but i like the lme49720

What's the op amp being used for?

 

How the op amp responds depends on the circuit and overall design, and that also has a large impact on what kind of effect (if any) it has on the sound.  It may not be a good idea to get something faster and pickier than the default, the OPA2134.  Unless you like tweaking for the sake of tweaking or experimentation, I wouldn't bother trying to outdo the default, which (I hope) was selected by somebody who knows what they're doing and designed the circuit in the first place.

Used for my Edifier R1900TII + Audiotrak Prodigy Cube

 

They might do the best or the optimum in the first place but the flavor I wanna hear is up to me right? Thus they allowed the opamps to change. Otherwise it would not be difficult to solder them to the PCB in the first place :)

I would definitely try AD8066. How it sounds on your circuit I have no idea, but it is superb as output buffer on Prodigy HD2 (togeher with 2xLT1358 as filter amps). See my post  http://www.head-fi.org/t/322497/audiotrak-prodigy-hd2-opamp-configurations-list/435#post_8626006
