Ah okay.. if it can fit with adapters, then definitely will be doing that

 

[ROBSCIX]

I just tested 3 with adapters for your guys and they allow you to put the sheilding back on and there is no contact with the sheild.

These ones are not that hard to find and they are very coomon. The models that are very hard to find are dual TO99 to DIP8.
Here is a link for the company that makes the To-99 to Dip8 adapters.->LINK
They do require soldering skills though.

you mean soldering skills are required to make that adapter or for TO99 chips when attaching them to adapter? i hope its not the latter.

Somebody just told me that I don't need to solder a TO-88 to DIP-8 pin a few hours ago?!
He said that you just need to solder it if you find it loose
Is it just the problem of this product or all adapters?

You need to solder the TO-99 ONTO the Dip8-adapter.. then you can just push the whole thing into the Dip-8 socket on the Essence.

If you do NOT want to use the adapter, you can just clip the pins on the TO-99 chip and bend them and try and fit them inside the DIP-8 socket. This is not recommended though.

Here is a pic of the adapter

And with a TO-99 soldered on,

I put three into a STX and there is more then enough clearance so you can use the adapter/opamp modules and replace your sheild.

I suspect, as ROBSCIX said, that the adapter would still allow installation of the EMI shield. If it doesn't though, there is no harm (IME) in removing the shield. I've tried listening with it on and off and I could not notice a difference in noise/interference, though it would depend on your specific case components. I recommend trying both ways to see if you can even hear a difference. The improved ventilation (of the opamps) may be worth more than the minuscule protection gained from the EMI shield.

 

[Bojamijams]

Yeah ROBSCIX is looking into the heating issue on the TO-99 opamps to see if its normal or oscillation induced.. but you're right, a little extra air going around there couldn't hurt

However he has confirmed that the shield will indeed fit even with adapter, so its just a choice thing now

Maybe he are thinking of a socket or something different. Most adapters I have seen that go from one foot print ot another E.g TO-99 to Dip8 -They require soldering.
The soldering produces solid physical and electrical joints between the opamps and the new pin footprint. There may be some type of adapters that don't require soldering but I have never seen them, or heard of them for that matter.

i tried to clip the pins but wasn't able to do it. like i said, i'm anything but handy. my soldering skills are nonexistent, so i guess 49720HA will have to stay in the cabinet. at least i didn't have to pay for them

out of curiosity - when soldering TO-99 chip onto that adapter, people cut the pins shorter? they seem to be too long for that purpose.

 

[ROBSCIX]

Yes I installed thre LME's in browndoag adapters and re-instaleld the sheilding. Ther is enough room. Atleast a few mm between the top of the opamp and the sheild.

As for the TO-99, yes your trim the pins short so they are just a bit longer then the bottom of the adapter. Atleast that is the way I have always built them.

So what's the final verdict on volume settings? I keep the speaker line-outs at 75% in Windows going to my amp, and the Essence Control Panel settings at the default 76% but it still bugs me.. At 100% it seems to have a little more bass and lose dynamic range but I could be wrong.

 

[leeperry]

ok I've just taken out the STX, the 49720HA were not hot AT ALL. I guess having a 25cm fan blowing at 1000rpm in the side door of my case took care of the problem.

I'm trying it w/ the NA atm, as I will be selling it w/ these....and sound is definitely different, more distant?

If they are oscillating, putting a fan on them or a heatsink will not help as they are malfunctioning. If they are indeed malfunctioning and it is not fixed you will have much larger issues then just hot opamps.
