Nothing wrong with the Cardas, I've used it for quite some time and it's worth the money, but... lately I found a .5 mm (diameter of the wire) alloy made of 60% solder, 38% lead and 2% copper, that costs much less and makes SMD soldering of opamps come out better...

It could be. Depends on how the buffer socket's connections are arranged. To use a (single) opamp as a buffer you must configure it as a unity gain follower, by either linking its pins 2 and 6 together or bridging them with a resistor, say 1K ohm. Maybe this is already done by the P3's...

If you want to use them as headphone drivers, the OPA1611/12 are much better than the OPA211/2211 since they have almost twice the output current. I want browndogs!

Hmm, nice, but the LT1028CS8 sounds better than the LT1057ACN8 for sure (as expected). My choice for the definitive opamp seems to be among LT1028 and OPA1611 ... unless I rediscover the LT1677 once again, LOL

Someone asked for a single version of the LT1057... well, that's easy. LT1056 (better) or LT1055.

Yes I loved the LT1028, but with all this talk about the LT1057 I wanted to hear it again... So I put it in, and at a first impression (after some time) it sounds very good. Like the expressive flowing mids, etc. It certainly has a different and probably more lifelike tonality than the...
