You guys need to get yourself two 2137P's... I've tried all the LME and they were all lacking in some sense.

By using 24bit, you negate the loss incurred by lowering the volume. Just don't push the volume over 76%, and set the gain to what ever works best, so for IEMs - low gain.

 

Thanks. I've followed the wiki and I have a couple of questions. 

 

Point 2 says "Set windows output to 2channel 24bit/48kHz" , then in point 7 it says "(Only for WASAPI - not ASIO) right click the Sound/Speaker icon in the taskbar, go to "Playback Devices", double click on "Speakers/Headphones", go to the "Advanced" Tab, set the default format to 24bit, 48kHz." Doesn't this make point 2 redundant? Or am I supposed to set these settings in two separate places?       

 

"control volume via system volume (76% maximum to avoid dynamic limiting)."  but ASIO prevents me from using system volume, and seems to just pump the sound out at 100%!?

 

Should I set to 48kHz in the Xonar audio controls too?

 

Thanks again!

It is redundant, with some versions of the drivers system volume control acts like a global control, changing the player volume too.

 

And its just a further explanation of how to set windows output.

Hello everyone! I'm interested in having a go at swapping OPamps in my STX and while I know how to, from past experience, I don't know what works. I've had some rather bad experiences at choosing OPamps, so bad that I almost baked a card. I think I put a AD797 or LME4910NA in a place that it didn't agree with... =(

 

Now, I want to know what works before I get stuck into it again. Can anyone suggest me OPamps and the best place to put them, assume that I've only using the headphone out? Would it be in the I/V stage?

If you only need the headphone out, then you will need 2 OpAmps for the buffer slots. For my past experience, the LME49860NA worked best so far. But i'm waiting for two AD8620BR which i expect to be better...

Okay, so I assume that the OPAmps that go in the buffer slots need to be the same? I need to ask this just in case I do something stupid. Also, how on earth are you running a T1 on and STX? I heard that wasn't possible.

Exactly, I/V's have to be the same, buffer may differ (or be the same also).

 

The Beyer T1 with my STX is a really damn hot combination. why should't that be possible?

STX supports headphones with max. 600 Ohms, so no Problem there at all :)

 

...still i'm looking hardly forward to my WA2 :)

Six LME49990 SOIC chips mounted on to 3 Dual SOIC to DIP-8 adapters.

Presoldered and ready to install, cost about $60, seller on eBay is Frugalphile.

 

Six AD797BR SOIC chip also mounted.

Ebay sellers name is China Jade, or Cha_jade, something like that.

Price around $35.

Just a question PurpleAngel, why do I need six of each? I thought the STX only had 3 swappable OPamps? If it's for the Essence One, I can understand as that thing has lots and lots replaceable slots.

The three op-amps used in the STX/ST are dual channel op-amps.

The LME49990 and AD797BR are single channel op-amps.

Oh! Is that so? I had no idea. Okay, now that makes sense.

But since he will be using the headphone out, he only needs 4 of them (for I/V) since buffer isn't used.

Very true, I just like the idea of having all op-amps match on the STX/ST,

Never know if in the future the card might be used with speakers.
