ok, I've rearranged my PC case and got rid of the dready extension leads...I still had to use two high-grade gold plated risers, though(as the red WIMA caps were getting in the way): http://img410.imageshack.us/img410/6924/hd2j.jpg
LT1124 is amazing, I'll put back the Earth later today...just to make sure I'm not imagining things ^^

Yeah, try that and report... I'm curious. Surely, the Burson has that nice looking 🙂 Mundorf cap, while the OPA-Earth has those two Evox MMK that probably aren't as nice (even if they're not fake)...
yeah SQ is really amazing, SS is so clear and natural....talk about euphonic sound 😛
the LT1124 was recommended by a chinese DAC builder that seems to really know what it's all about. I really don't recall getting this goosebump machine from Earth.

I would say the same about my DAC that's now playing the XTC's "Homespun". 😛
Nothing's out of place, everything sounds right and in proper balance with all the rest.

alright!! after many hours of "OMG THIS CAN'T BE" on the Burson+1124, it was time for an emergency crash landing on Earth...well, did I already kill the suspense altogether? 😀
it sounds terrible...you still have the uber-wide SS, but trebles are distorted and colored to death.
SS is much less natural, trebles are ugly to listen to, bass is also distorted...Earth is clearly killing the LT1124ACN8 grain, the burson was embelishing it like you wouldn't believe.
upgrades have that nasty side effect than any previous one is laughable at best 😀
sound is nice on Earth, especially considering the price...but it lacks the uber-transparency of the Burson, basically the new Burson is like an Earth, but much clearer/natural sounding w/ a much better stereo coherence..there's much less bloat between you and the music.
ok time to roll back! then tomorrow try OPA228P/LT1028ACN8/LT1363CN8, also AD797BN when I'll have them...and the quest will have pretty much reached its end for me(LT1630/1632 will be tried as well)
and don't tell me about 3 burson's, too damn pricey...and I'm not sure they'd sound good as AK4396 LPF, Slash47 told me that they'd give a more analog sound(digitalitis will be cured) but not necessarily more details......I just want one as final buffer to allow a very clean DAC output to blossom into some giant killer plant

okay, just put back the Burson after several hours of OPA-Earth suffering...OMG, the difference is literally night & day 😛
bass is tighter, SS is more natural and MUCH clearer, voices sound true to life, trebles are very clean..ouch, it hurts 😀
you could compare them as a 10€ cheapo entry-level Champagne bottle against a killer 500€ Veuve Clicquot "Vintage Reserve"...both will get you drunk, but the later will taste FAR better
now I'm thinking about putting three burson's, nasty upgraditis 🙄

Burson says that Audio-GD has been pirating their chip, Chinese copies...you know the deal, the same...just crappier.
Well, I spoke w/ Slash47 and he tells me that 3*Burson's will give high PRAT, but not necessarily more details..
the same way LM4562 likes to bring aloud very tiny details hidden the back, most IC's dig very deep to show you what's hidden...LM4562 is of course an extreme case!
he tells me that some AD797B would do pretty much the same job as DAC LPF, and putting 3 Bursons would require some cap pimping on the card itself to pimp things up.
I'm not convinced by the 4*OPA228P...I guess you read my post on head-fi 🙂
I'm getting desynchronized dual mono instead of stereo whenever I use single chips on adapters 🙁

It makes no sense that you would be getting strange effects from just using two singles instead of one dual... all the more so when the two browndogged singles serve the same channel! 🙂
What you're not convinced by must be the somehow awkward soundstage presented by the OPA228.
Regarding the LM4562 and the tiny details, I don't find it digs into them as much as an LT1028. I find it has a dryish sound that at a superficial listen may sound like very detailed (the OPA827 being kind of midway between LM4562 and LT1028 in giving such an impression). The LME49723 sounds better, retaining the detail and adding body and color where due.

And yes, 3 Burson's on a PC soundcard would be pretty kitsch, almost grotesque, wouldn't it

well, each time I've tried 4*singles on the DAC output, I've found the stereo coherence severaly foobar'ed...but my headphones are also single ended, so delay adds up in the end maybe.
ah well, 2*1124+Burson is great..I don't really care about how my soundcard looks like, when that rolling frenzy will be over(and I'm tellign you, it will! 😀), I'll do as usual...open the case once a month to remove dust 😛

Not only for how it looks... consider the proportions of cost... besides the fact that it's all stuck inside a PC, not the most audiophile of places on earth 😛
Also, I've heard that the Burson is not perfection in terms of coherence over the spectrum...so too many of them might steer you from a balanced and enjoyable sound more than you expect. Of course, I haven't heard it, but if it follows the Audio-gd's opamps tendency to suck out the midbass (OPA-Sun V2 excepted)...

I can get two Burson's for around 100 EUR, but then I need two more mundorfs caps and get an electronics shop to put them on for me.
anyway! LT1124ACN8 + Burson plays music exactly the way I want to hear it...both that shop around my place, you and burson advise to ditch sockets and solder directly to the PCB.
I might very well get the 2*LT1124ACN8 + Burson soldered(w/ cardas eutectic), and call it a day 😛
one of the legs of a 1124 was slightly bent and the left channel was popping and was softer than the right one...I had to bend it properly again to get proper stereo sound, sockets DO kill SQ 😱
top quality sockets(full thick gold plating) cost 0.3 EUR a pop if you buy 5000...manufacturers really go cheap on the wrong parts...the worst being Asus on their ST/STX, they're not even machined!

Metal Cans vs plastic
Have any of you compared (in your subjective listening tests) the metal can National parts (LME49710/20HA VFB or LME49713HA) to the various plastic parts that you like? To bad NONE of the most recent National parts will ever make it to metal cans with all us high end guys laid off to push for them!

hi audioman, nice to see you here!
well I've compared 720HA Vs 4562NA and 720NA.
49720NA has always been bass shy to death(the low end bass is just GONE), and the trebles are pretty whiney..SS width is also great but its depth is dumbed down...it seems to cut the SS in several layers but it doesn't sound natural, and it fetches tiny details to put them at the first row. very impressive for a little while, but gets boring rather quickly tbh.
4562NA was the same, but the trebles weren't so whiney..less refined maybe? I know they're supposed to be the same exact part, but I'm far from being the only one hearing them different.
and last (but not least 😀), the 49720HA, well...low end bass is back with a vengeance! I have a hard time believing it's the same exact piece of waffer as the NA..but SS is still artificial sounding and trebles are somewhat on the dark side.
to sum up, these parts are very impressive when you don't know them, but many ppl get bored rather quickly.
I think Andrea loves the 49723/725MA(and so do other ppl on head-fi), these two are supposed to be major improvements...I personally tried 722MA(the THD rate is very impressive) but it sounded like a 720NA to me basically, verrrrrrrry bright and artificial sounding 😱

Sure I have, I compared LME49710NA and HA in the Musiland SVDAC05 and LME49720NA and HA in the Super Pro.
Funnily in the SVDAC05 what I preferred was the LME49710NA for a slightly more real (if also a bit lightweight) sound.
Instead in the Super Pro I definitely preferred the LME49720HA, so much that it became one of my few favorites (see first post), and rivalled the LT1028CS8 as my final choice. Though eventually I chose the latter and I haven't regretted it. I loved the LME49720HA but I find that it's more colored than an LT1028CS8 or ACN8.
The LME49720HA had that groovy sound... but refined too, and endowed with very interesting tonal qualities. Yet it sometimes sounded coldly analytical in the mid-treble, for instance with the XTC.
Also, speaking of these TO99 variants, I find they have a kind of metallic glare to them that the plastic siblings don't. That's why the LME49723 is my favorite dual opamp, not the LME49720HA. Maybe (or maybe not) the LME49725 will equal or surpass the LME49723 when I get to try it.

The real deal among bipolars remains the LT1028 for me. 
Instead for the FET-inputs I believe the ADA4627-1 must be great... but this requires a confirmation 🙄
