Sun v.2 at +-15V is the only complete discrete op-amp, with a touch of wooly-woody-something added. The OPA Earth is like a cleaner AD8397 but tonality is not 100% complete. The OPA-Moon is sweet but tonally even less complete.
Regarding the my "top three" - yes, the OPA211 is great. After listening with the RS1's I borrowed from my friend I have to admit LT1028ACN8 is the best in imaging and smoothness. Best for both GS1000 and RS1.
AD797ANZ is as worse as the BRZ series, as the LT1028CN8 is worse than ACN8 series. Both suffer slight dryness, while the ACN8 is British rich and smooth. I have to say that after further modifications of my DAC - BG added to power supply and analog multiplexer bypass, now it looks like this. The most analog sounding are LME49710NA but they exaggerrate in this to the level imaging is blurry, and soundstage slightly congested. The LT1028AN8 is perfect but with its own, very delicate timbre, less present than in other op-amps like OPA2228 or LM4562.
Regarding measurements - I can't do that and I don't care for their results actually. I am of course curious of listening to some new toys/
NelsonVandal, you're welcome.
Regarding IC's - I have to try out the LME49722, it's like decompensated LME49720. Sounds delicious.
My current recommendation list:
1. 2x LT1028ACN8
2. 2x OPA211ID (issues like in the review)
3. 2x AD797BRZ (finally I found slight imaging issues and timbral imbalance)
4. LME49720MA / 2x LME49710NA (I guess I like the former a bit more)
5. OPA-Sun v.2 (thick, flawless, likeable sound)
No more unconditial recommedations at the moment.
