It is opamp rollable...I don't see how it is soldered in....
care to share some pictures?
he didnt do anything...he mailed me the opamps and i swapped them myself. that was after i installed bybass buffers and different oamp. the picture you have is one of soldered bypassbuffers and a dual 2:1 opamp.
there arent that many good instructions online...but you can pop off all 3 of those chips, the 2 buffers on the left and the 1 opamp on the right. carefully lift them up and wiggle them out vertically. take the opamp off first since you can get leverage from the right as there isnt much blocking your way. get like a knife or something and slightly pry it up. be very gently. after a little work itll be coming right off and you should be able to pull them out like pulling out a nail from a wall.
you cannot have a soldered d4 unless you bought an aftermarket used one that someone soldered. online it advertises rollable opamps, and it should be rollable...
also i think it needs to be said that the opa1611 is a single channel opamp,the opa1612 is a dual, so you will need a dual soic to dip8 adapter with 2 x opa1611 soldered onto it to replace the stock opamp if there is only one socket for the gain stage (rather than 2 for the buffers)
Anyone know if its ok to plug the D4 into a usb hub? From what I understand a hub splits the current between different usb devices; will the D4 become underpowered and cause the SQ to degrade?
I think I have a problem with my D4, when I use the amp section it works fine, like when I use it out of my phone. But when I use it with my computer using the dac+amp, it makes the bass sound crackly, and overall worse than when using just the amp section. Could it be because my phone has a better dac than the D4? Or does it have to do with clipping and if so how is this solved besides selling it and buying something else?
