The buffer is not used when in headphones mode. When using the line output, you can use the buffer to tune the sound produced by the I/V.
In line out mode, all three opamps are used. In headphone mode the buffer opamp is replaced by the can amplifier chip.

Thanks!

Will be back with some impressions as soon as I get my opamps!

Well they are great for music too, the reason I liked them more for games is because they gave me a wider soundstage in comparison to any other Opamp I have tried till this moment.

The LM4562NA and LME49720NA are said to be the exact same amplifier with the only differences being the label. That information was suggested to me by the manufacturers of the chip. they also said they would have di-continued the LM lineup but the chip won many awards and is well known. No that being said some suggest they hear differences. We are only talking about the DIP8 versions as TO-99 would be of higher quality.

I could certainly hear the differences right away, even with such an "untrained" ear.

A quick update guys, I've just ordered 5 „free” LME49720NA samples from NS and I'm eagerly awaiting their arrival... How long do you guys think it may take them to ship the opamps to Romania? I payed like 8$ for handling and shipping using my credit card, I hope they didn't rip me off...

 

[ROBSCIX]

You'll get them. The LM49720NA are the same as the LM4562NA...
If you use these for I/V they should give you a noticable improvement on your soudn quality.

 

[Steve-o27]

That's good to hear!

I basically only need two (or three if I use one in the buffer spot) so I'll give the rest away for free for the ones in need.

Can't wait to really hear the difference these boys make... I'll keep you posted as soon as these puppies arrive!

it seems like LME49860NA beats them all. So, ppl, don't waste your time and money for LM49720NA, LM4562NA anymore.

..it seems like that is an opinion and nothing more.

If you are using the headphones then yes, you would onlt use the two opamps that are side by side. If you are using the line outs then you would use three but as I said the stock opamp is the same as the units you are ordering. You may not like the signature produces by using three of the same opamp int eh IV and single end buffer.

I just ordered a AD797BRZ to test on the buffer, lets see how that goes

It's based on another... yes, opinions. Need link to russian forum? :wink_face:

Another quick question: Can I use one of the stock I/Vs from the card in the buffer spot after the new opamps have arrived? I read that the LME49720NA in the I/V spot + the JRC2114D make a pretty good team.

 

[shimm]

IMO, there is no place for 2114 in this card. You better stay with LM4562 in LPF.

you certainly can. i used to be running on 2xLME49720HA + JRC2114D @ buffer. while sound was ok in many areas, especially the tonality, JRC2114D has tendency to put a veil on music. other way around you will get more transparent sound, while keeping most of the tonality of the former.

a little reminder, 49720HA has slightly different character than 49720NA, so i wouldn't be surprised if you got same results with stock op-amps setup and the 2xJRC + 720NA setup.

Point being you cannot say one is just the best and ignore the others.
Many tried those awhile back in this thread and didn't really like them so they moved on.
