Can you define too mellow sounding, please?
Well, I.rolled opamps in a cmoy, the burr brown opa2134, and it was slow and mellow with tubby bass, then I had the LME 49720 and that was fast, lively with details a lot easier to pick out.
Burr brown was not for me. The mids are smooth and warm, tubby bass with fairly good highs. I prefer lively, a little bright, fast and detailed.
Oh, then you're earning your name as being the random kid! You're comparing totally different opamps in a different amp and using those to make judgements about the sound of the two C421 options. Somehow, I don't think it works that way. Just because you found the OPA2134 to sound a certain way doesn't mean the OPA2227 will sound similar; likewise with the LME 49720 and the 8620.
no mean to offend, look here, the AD8620 is know to be fast and detailed, and a little bright just like the LME49720, and i have had both as you know.
also the OPA2134 is very similar to the 2227:

Read please
How tight is the headphone jack on your C421? Mine allows some wiggling of the headphone cable and the sound cuts in and out and makes some popping, static noise when the cord is moved. JDS Labs was super cool about it and I sent it back. They will take care of me so I'm not worried, but I wondered if it was just me. They were very nice about it.
That is true. All cool now. But the general consensus us that burr brow have a laid back smooth sound, whereas AD have a more detailed agressive sound
No problems on mine and I haven't heard much regarding this. So maybe it's an isolated thing!?
