you mean these LT1363CN8#PBF http://www.linear.com/pc/productDetail.jsp?navId=H0,C1,C1154,C1009,C1022,P1108
 
Are those singles or doubles? I think given the "PDIP" they should work as is, right?

more like 2*CS8 on an adapter:

ahh, so the CN8 chips need adapters? I don't know how to solder yet, but i plan on learning in a few weeks. In the mean time i'm looking to avoid ones that need adapters.
 
Also, that only looks like one chip? Where's the other one?
 

 

[leeperry]

the other chip is on the bottom side....two single opamps on an adapter will alway sound FAR better than a dual opamp, so I'd advise to learn how to solder and not waste your time: http://tangentsoft.net/elec/movies/
 
it's far easier than it seems, just get a 30W iron and some low melting point solder

Thanks. You know, i did have the thought "I wonder if a single opamp sounds better than a dual in the way that a single ended tube sound better than a push-pull"
 
Is it a similar situation?

 

[leeperry]

not sure, but dual mono always kills stereo in the audio world...even TI acknowledged the problem, but still failed blatantly as two OPA1611 do sound much better than one OPA1612: http://focus.ti.com/docs/prod/folders/print/opa1612.html
 

 The dual version features completely independent circuitry for lowest crosstalk and freedom from interactions between channels

Well i'm still confused by all this. When you recommend LT1363 (avail here  http://www.linear.com/pc/productDetail.jsp?navId=H0,C1,C1154,C1009,C1022,P1108 ) or someone else reccomends a AD797BRZ (avail here http://www.analog.com/en/other-products/militaryaerospace/ad797/products/product.html )  how do i read off those chip types and know which will need adaptors because they are singles and which won't?
 

 

[leeperry]

ad797/lt1363 are singles indeed, reading the datasheets helps when you're not sure

 

[bearcatsandor]

Um..yes..thanks. *looks embarrassed and hides in a corner*

 

[leeperry]

lol, no need to...just check the datasheet for the opamp pinout, if it says IN1/IN2/OUT1/OUT2 it's a dual.

 

[bearcatsandor]

Thanks. That makes a lot of sense actually. This thread has been full of so much awesome information
 
By the way, i've downloaded those videos on how-to solder and will be watching them soon. They should help when my friend teaches me how to do it myself.

I think i've settled my opamp little adventure by choosing LME49720HA on I/V with LT1364 on buffer. The sound is so clear with lot of musical detail and  bass has enough quantity as well.
With LM4562NA on buffer the sound was as clear as crystal but lack of bass extension i though.
With OPA2134 on buffer the sound was muddy, bass was to much and the high was dull. i don't know if it called warm but i didn't like it.
 
Someone has suggested LT1364 opamp somewhere on this thread to compensate the lack of bass quantity in LM4562. I thank you for that. To bad i can't continue my curious for other opamps variation because every little opamp here must be buy to get with high price as well.

Yes, common opamp information posted in the DIY opamps thread.  If you are looking for good opamp information, that woudl be the place to get it.  IIRC, the 1364 dual and 1363 singles weren't that popular using these cards.  Your tastes may vary.

Does the Xonar ST control center change upon connecting the H6 or do you need to reinstall the drivers in order for the sound card to recognize the H6 daughter board?

The drive just reconfigures itself.  You don't have to reinstall..etc.

Thanks for the info and the pointer!  *starts to read* There are almost 3k posts in that thread! wow.  *falls over dead*
 
It would be great if we had some sort of indexing system where a person could look up a chart of these opamps and see (on a score of  1 - 10) which what amount of highs, lows, soundstaging, grain, etc.
 
There seem to be hundreds of combonations and a person could spend lots of time and money doing this.
 
I know we can't really ask "What's the best?" as it all depends on one's system and hearing, but if we know our systems well enough we know that we'll want an opamp that's darker to tame a bright speaker or faster to improve a sludgy big woofer system.
