No soldering required, it's a very simple drop-in procedure, there are even pictures and instructions somewhere in this thread.

Which version of the Fun did you get? New? Old? A? B?

It was easy to put the Earth in, but removing the original op-amp was rageface inducing without the right tools. Tweezers just about did the job.

It was shipped on 7.19.2011 so I think it's the newest possible. And "A" maybe. Nothing was mentioned about "A" or "B" in the offer, "A" is by default.
I'll be glad to explain me what's de difference between the old and the new version.

Mine came out very easily with a sharp nose plier.

the new one and version B doesn't have the wm8741 by default... and it sounded like you were describing the old ad dac chip, but even the old dac chip had good dynamics and was very 3D. How many hours do you have on the unit? Also are you using as a dac/amp combo? or just dac? or just amp?
 
Plus you need to get that opamp out of there. It is seriously a place holder for one of the audio-gd opa's.... and the opas are discrete so they need burn in also.

hmmm...... now I see the what was written in the offer in my e-mail box: "FUN Version A (WM8805)". But this is the S/PDIF interface.
What is the DAC chip then?? It their site audio-gd still mention wm8741 as DAC.

 

[2real]

I think there really isn't a "B Version" anymore.

The DAC chip is really the wm8741, unless you asked for a different one.

Nice CD, thanks for sharing.

Unfortunately the FUN + Shure SRH-840 combo is a disaster

A terrible peak in the upper mids is combined with a drop in the bass and the result is an unnatural thin and squeaky sound. If I turn the volume up more than 10 o'clock it becomes unlistenable. Terrible combination... sorry to say that. I doubt any further burn-in will change this. I think any of the two components are not that bad but have their own pecularities, which are superimposed one over another.

 

[sphinxvc]

That's unfortunate.  You could try rolling some op-amps to see if that alleviates the issue.  Actually, do you have any other headphones handy to rule out a faulty unit?

I doubt it's an amp's malfunction.
I'll try the Earth OPA... If I can install it properly

 

[brat]

well, the Earth solved the problems with bass and mids almost completely.

This OPA2134 must be an absolute crap.
Now the FR is more flat except a new emphasis in highs but I know the 840s are supposed to have a problem in this area according to the graphs.
