Regarding the Linear Technology duals, I believe the LT1358 and the LT1469 could be considered the best overall, with the possible addition of the LT1124 that I have yet to try.

The LT1358 can sound excellent, more enjoyable and with a better transient response than the LM4562, give it a try...

I prefer AD8599 to LME49720. I has a more appealing sound. It's not on par with eg OPA827, but I think it's a damned good opamp. I'm sorry I haven't heard any LT chips, but quite a lot of the AD, and some of theTI and National chips, and amongst them I think it's the best dual opamp.

Have you tried the LME49723 and the LME49720HA ? I think the LME49720HA in particular sounds superior to the OPA827.

The LME49720NA is indeed not too appealing... that's why I prefer the two above.


Edit: It's a bit contradictory to me that you should find the LME49720NA not appealing enough when you seem to like the OPA827 that much. I find that the latter has an even duller tonal character.

The LME49725 should be more appealing than the LME49720NA, as well.

I guess I have to make a Digikey order after the holidays. So many opamps to try.

Hmm, which of these LTs have you listened to?

The OPA2228 is pretty good; but the OPA2227P too isn't nearly as bad as certain people claim.

The AD8620 and (even worse) AD8066 don't sound natural to my ears. The same for the AD746 (without external biasing), but here it's just because it's quite cold sounding. The OPA2111 is OK, but nothing extraordinary. The OPA2211 has tonal issues (tonally it's limited, plainly; like the OPA827) just like the single version; my hope is that the OPA1611/1612 would have fixed this (I won't know until I try).


At present most universally good sounding dual opamps are those I mentioned from National... LME49723, LME49720HA, probably LME49725 when I try it too.
