Don't be naive.
This coming from someone with 3 posts!

I'm trying to get the thread moving again, I suggest you deal with your paranoia buddy and move to another thread if you've nothing to say regarding the OP.

how about the OPA2111? I'm only reading raving reviews about it, they just popped in the mail...will try them later, even though I'm really in love w/ the 4562NA sound...more "hifi" than the 49720 as this site puts it :

This op-amp is essentially the same as the LM4562 but on A/B tests we have found the LME49720 is less “Hi-Fi” sounding.
PS: you complain about the mods in here? go to the hydrogen-audio forum, these ppl are nutcases..

I bought the single (OPA211) version so I could run them in Class A, it will be different in different circuits and with different phones but in my P3+ I struggled to tame the bass. That said, it was quality bass, just too much for my liking. As for it's other qualities? well as everyone says it's a fine OpAmp and not much to dislike really.

I've always been under the impression that the 4562NA would blow pretty much any other op-amp out of the water(except for the discrete ones of course)...can you get the same HUGE soundstage and distortion-free trebles on another chip? anyway, I'll be soon to find out

Ideally I'd like to have a 4562NA w/ a tad more low end bass...then I'd call it a day

OPA2211A is about to be tested. Based upon experience with OPA211, I suspect that I'll prefer it to LM4562/LME49720.

I understand that on occasions people disagree but it seems that the grudges people hold seem to bleed into other threads and that's when the rot sets in. I WAS enjoying hearing about other peoples experiences and thoughts regards this thread, don't agree with some of it, but as I always say what ever you hear is a person thing and always subjective. Can we just move along now?

What's the story with Majkel? He/She and I were having a great chat and now their posts are removed. My posts/replies don't make a great deal of sense since Majkels replies/posts were removed.
Here's who Andrea is:

His problem is he bleeds over into lots of threads and becomes disruptive. Very disruptive sometimes. He has been banned 100's of times in about 5 years and is a truly Pathetic individual. Don't encourage this pathetic lump.

So, perhaps not surprisingly, OPA2211A sounds very similar to 2 x OPA211 on a BrownDog 020302 adapter. Compared to LM4562, the OPA2211A sounds more open, yet not harsh, in the highs, with a nice, dare I say, "natural" roundness and warmth, while the LM4562 sounds more sterile and flat. Or maybe the OPA2211A is colored in euphonic way..... In any case, I like it.

Also gave the LT1358 a quick audition... and it didn't impress me particularly. Not bad, just not much different than the LM4562, and not as good as the OPA2211A, IMO, though my K702s are out of commission at the moment, which necessitates using my K240Ms, so that might obscure some of the nuances. I'll try to rig up 2 x AD797 in the near future.

Just tossed my NE5532 for a THS4032CD... I'm not even curious about other opamps now.

I just built 2 -211 modules (opamps and brown dogs) but have had little time to test them. what I heard though I liked. I may have to check the 2211's...so many surface mount chips.

Where was it? Sure it was stable (it's not a regular audio opamp, it's fast)?


That said, I do prefer the LT1355 to the LT1358. To me there's a slight muddiness in the latter that is not in the former.


Having said all that, the OPA211 is growing on me... But I still miss the vivid tonal color of the LT1355. It just gave Tom Waits or Lucinda Williams the right 'intensity'. I surey prefer it for my DAC to the LM4562, which to me is nice but not excellent in anything, neither resolution nor natural color.


Finally, the TLE2062 is making my 24V CMOY fly... Someone else should take advantage of it.
You've been reported...

I rate the LME49860 higher than the THS4032. They are similar but the last one simplifies tonality a small bit. I still think the LME49860 is my favorite dual op-amp. Not so thick and smeary as the LM4562 and not so bland as the LME49720.

While clear and authoritative sounding, I found the THS4032 missing some body in the midrange - it sounded a bit artificial to my ears. The OPA2211A, on the other hand, sounds clear, yet warm throughout the audio band, IMO.

interesting! I would indeed love a mix between the 4562 and 49720...w/ a tad more low end bass on top.

in my tests, the 49720NA had very clear top trebles, but the bass really lacked...and the 4562NA had very clear bass(not quite perfect though, but very much acceptable) but the top trebles sounded muffled...yet clear, but just not as clear the 49720NA.

the 49720HA had tons of bass, but the top trebles sounded muffled as well.

so now you tell me about the 49860? I thought these were the high voltage version of the 49720?

anyway, I will try the OPA2111 later today, hopefully it'll be my golden ticket...everyone praises it :

At the risk of repeating myself, I suggest trying the OPA2211A. Somehow I'm doubtful of older chips like the OPA2107, OPA2111, etc....
