Some other parts which might be worth listening to are THS4032 for I/V and OPA211 x 2 for output (both SOIC).

yes, I did try the 49720...but I was using the ASIO drivers in foobar, and they stink big time! so at point, I put back the stock op-amps and was about it to call it a game and sell the card...when I remembered that KS was said to sound better, and it does! so I'll let the 4562 burn in for a few days, and I might very well try the 49720 again

the other op-amps are mostly SOIC8, I want something that just fits...w/o the huge markups from ppl who solder them on DIP8 adapters on ebay(and what if they mess up? I really don't wanna fry the card

)

one thing I'm curious about is that the TO99 metal versions are known to sound even better! but I thought the length of the legs was most critical?!

some ppl solder them on DIP8 adapters for lot of $$$(still on ebay) and some other ppl just fit them somehow in the DIP8 holders

anyway, once I'll have made up my mind on 4562 or 49720, I might fancy some metal versions

PS: AHMAGAD, the 4562 is mind blowing on Ed Rush's DNB...such a wide soundstage and detailed sound

Here's an example of an SOIC on a DIP socket.... best I could find with a short search.

it's true that the 4562 is "dry"(it's only a few hours old, though), but the 2114 sounded distorted anyway...and all the micro-details that float "above the surface" are just very impressive(together w/ the HUGE soundstage

)

I personally like to wear correction glasses made of thick 1.5 mineral glass, because their resolution(Optical transfer function - Wikipedia, the free encyclopedia) is higher than my eyes..I can't stand plastic glasses, they feel blurry.

it's the same thing, the 4562 sounds more detailed than my ears...love the feeling

I could listen several times to the same track and hear different stuff, it sounds so highly refined

it's funny when ppl tell you that every disc you listen to has gone through hundreds of 5532/2068 anyway, so there wouldn't be any point to use something better

PS1: I thought this saturation test was pointless because the sample were lofi to begin w/....but w/ a proper soundcard/op-amps, it's a lot more manageable :



PS2: the Babel OST finally gives! w/ all these spanish guitars

I've used Browndog SOIC/DIP adapters in the past for duals (and still do for dual single SOIC to DIP). However, these days usually I just carefully splay out the SOIC pins and solder a dual SOIC device directly to a DIP socket. The inner four pins (2, 3, 6, 7) should be right on the edge of the DIP socket's inner holes, while you might need a small resistor lead or other piece of wire for the outer pins (1, 4, 5, 8). Just be careful with heat so the socket doesn't melt!

I have to order a few of those this week and finish up my opamps modules I have been wanting to build. You reminded me I have to put a order in at brown dog.

It's a case of synergy.... you are using the K702 and it's 'dry' by nature. Had you been using the AD2000 like me you'll certainly prefer the LME49720.

isn´t lm4562 stock or?

same for me.

so nobody is experiencing a popping sound when switching from HP to 2 speakers in drivers?

Not sure what you mean by popping, but I hear a short, high frequency tick.

 

[dex85]

thats what i meant, my english can be sloppy sometimes

i'm concerned about how loud it is though, that it could affect the drivers in headphones after hundreds of switches. but i guess im just being a paranoid like i said earlier

 

[Cynips]

It's not loud enough to make me worry the least even though the hf energy certainly is subsantial. Also, it seems independent of my Win volume setting.

Wow that was creative...
But if not careful enough, those pins might break...

There are three opamps on the STX. Two are JRC2114D's and the other is a LM4562NA.

He is changing the 2114D's to LM4562NA...

ebay isnt your only choice for pre mounted op-amps,Cimarron technology sells pre mounted OPA827's and what not for 49 dollars.

edit: Robscix is the OPA211 like the OPA2134 or some what diffent?

 

[dex85]

does anybody knows what is the headphone output impedance? i don't see it anywhere on the asus website. and does it change with different gains or remains constant?
