Try the LT1355. 1 mA per channel of quiescent current and sounds better than two LME49710.

I'm tooo curious about the OPA2822 (just received 5 of them) in my 12V DAC. It might turn out as the ideal solution, even. Adapters pleaaase coooome...

Quote: Originally Posted by FallenAngel If you got the AD797, you're something special, it's a VERY hard opamp to get to work. OPA211 is no slouch either, also a terrible bipolar to stabilize. Since you're asking about TO99 package vs DIP8, hi Andrea The AD797 worked just...

Quote: Originally Posted by Pluto2 Hi hopeless, Decided to try out the LT1469 & LT1358 combination, and about to order a bunch of LT1469s for the filters (too bad only SOIC is available at digikey). Will swap around later with the LMEs I have. Thanks for the advice I...

Quote: Originally Posted by FallenAngel I also really have to say the LME49710 is nice, but certainly not "very good". It's a good chip when restricted to certain voltages (which is why I use it behind a buffer in my portable amp), but I definitely wouldn't drive headphones with it, nor...

Quote: Originally Posted by FallenAngel Yuk, hated the OPA228 at 9-32V, unbearable highs without buffer, just as bad behind one. Haven't tried LT1468 or AD827. Don't know much about all of these LT chips, not much info on them (except the insane ravings of andrea). Don't...

Quote: Originally Posted by FallenAngel Really should state the PURPOSE of the opamp you are recommending. I/V - I've heard great things of the OPA1632 for I/V - TwistedPearAudio uses it and I must admit, I love their stuff. For I/V it's much simpler to use the LT1468. I've...

Quote: Originally Posted by Bonthouse Very true. But with enough flux, a 225 degrees celsius soldering tip and a steady hand it's possible to do it enough times. But lets say I want to improve the bass just a little, but keep this opamp. Would different signal caps do the trick? I...

Quote: Originally Posted by BobMcN My CD player (an Ayre CX7e) uses the AD844's. Don't know if they can drive headphones either, but they do sound warm and inviting with plenty of detail. The music just flows. Very analogue like presentation with kick ass bass extension and drive...

Quote: Originally Posted by SpudHarris Er sorry...... but I'm using them in my P3+ driving headphones. I didn't pay too much attention to the SOIC in Sam's post as I did not understand why it would need to be SOIC? Doesn't the move use DIP sockets? Do you actually have the AD744's...

Quote: Originally Posted by Pluto2 Maybe it's all system dependent? I did replace a LM4562 with LT1358. I think LT1358 has better clarity and spatial resolution and sweeter voice.... I definitely don't disagree. BTW the LT1355 is wonderful also with Jolie Holland's latest...

Hey majkel, I've just put two OPA228P inside my evolved CMOY and it's working (sounding) great. Thanks for the suggestion. It's a little bit better than the AD845KN -- slightly smoother and heavier mids, slightly more neutral tonality. On the other hand, the AD843 was perhaps the best...

Quote: Originally Posted by 12Bass Although it has been some time since I listened to it, I seem to recall finding the LT1358 fairly clear yet somewhat thin sounding and preferring the perhaps more neutral LM/LME parts from National (and later preferring the OPA211). Haven't tried the...

Still finding the LT1355 to be transparent and unobtrusive - very important for me. I remember the OPA211 (in the other DAC, at +/- 15V) sounding a bit "peculiar", with a certain (often interesting BTW) coloration in the midbass, for instance.

Hm, with a single +5V power supply (and with the subsequent CMOS opamps) ... And with small power supply capacitance too ...

Quote: Originally Posted by Pluto2 Thanks hopeless, But what happened to your beloved LT1355? And you don't like lt1352, why? Is opa2211 good for filtering, I thought the input current was not low, yes? .. I'm listening to my DAC with the LT1355 still inside... Sounds great...

Hmm the LT1124 looks good; like a better (bipolar) LT1057. Try the LT1122 too - very good FET single opamp.

Ouch, wait, I guess the LT's are worth nothing to you.
