This is the best tool for removing any size chip that I've found that doesn't require a lot of force and doesn't damage the IC.  Stick under one side and lift up a bit, go the the other side and lift up a bit ... repeat until chip is free.

I do the exact same thing but with two of those on each side and gently push them down (left, right, left right).
It will look like this: (The "\" and "/" are the flat screwdrivers and the "-" being the opamp): \-/
It will plop right off with, most of the time and with no bending at all. Like you said.
If I try the IC-Clamp / tweezer in an upwards vertical motion way, like it's described in the manual or from you guys, the pins always tend to bend heavily. It is just too risky for me that way.

The smaller one should be better. However, you can do it just fine with a flat screwdriver or a good pincette.

I compared the 49720na and ha and i found that the ha was brighter but even with dark sounding instruments clarity and separation seemed better so it is probably not just the added brightness. I also listen to mostly acoustic recordings when testing sound quality. I am goin to try the 49710 once the adapters arrive.


The same for me, I use 49720ha  at headphone and XLR buffers. Looking for 49710.

Frequency response at 96 kHz sampling.
Blue = normal, Brown=upsampling
 

Frequency response at 44.1 kHz sampling.
Blue = normal, Brown=upsampling
 
Measured with Terratec EWX 24/96 souncard.
At lower picture phase response was not calibrated, but shows relation.

Thank you for sharing.
 
Appreciate your take on the measurements.

I have two different removal tools.
The OP-AMP Remover, and when i can't find it, i use a standard clamp.
It has to have the word "Durabuilt" on it, or else it's not built to be durable.
 

 
 
 
 
 
Please tell me you slowly rock it out of the socket and don't just yank. I think I may have had mini stroke when I saw this picture.
 
Edit: Didn't read further on after I saw this, as you already answered my question.

The best way I've found to remove ICs, both at home and in my former profession, is to use a small flat head screwdriver. Place it underneath the chip and twist a little. Swap to the other side and do the same, repeat until its almost out of the socket and you'll be able to remove it by hand.

Yep, thats a good method. I'll do that on hard to reach spots too. Just make sure not to scratch the socket or the bottom of the opamp too much.

I tried the srewdriver method the problem starts where it always comes out at one side only first and the other side is still in the socket pretty firmly.In this situation you won´t get it out without bending the legs.I am using [size=11.818181991577148px]combination pliers, it can grab the op-s pretty tight and then i can simply pull them straight out without bending any legs.[/size]

We  really could use a video demonstrating the best way for removing the opamps or similar , any volunteer?

I'll do it.
 
I'll show you 3 different methods.
 
Should i record on a Nikon D3200 or iPhone 4S? 
 
OH! Finally i can make use of my Blue Yeti Pro microphone.
Bought it years ago but never had any reason to use it.
 
I KNEW THIS DAY WOULD COME!

Did anyone find out if Asus has included the the gain switcher on all the Muses editions or was there an error somewhere and not all of them have it?  I am using the Denon D7000 with the Muses and never go about 8'oclock position.  It gets way to loud above that.

They probably didn't put gain switch on any of them.
 
And i noticed you're using Audioengine A5+!
 
High five brother!
