Its all the fun and its easy to forget yourself:lol: I guess I could add the tried and tested stuff to the first post just so things don't get too spread out again:)

Regarding the op-amps, THS4032 was a little ringy in the highs without ML5/6, you can see this on the scope, it'll be ok ish one minute and then go touchy

Quite a few other op-amps will work with these caps removed, its mainly the fast high bandwidth types you have to be careful with

I currently use metal can LM4562HA with ML5/6 removed, it sounds really refined with a classA amp, nice bass, tight but full.
With a classA/B it sounded more lean, gives the impression of less body
Sounds great with both amps but I understand why some maybe finding some slight lack of weight using LM4562
Best thing to do is compare a few types and see what matches best with your kit.

BTW, I found the metal can LM4562HA better than plastic LM4562NA, the improvement is only small though so if you don't like LM4562NA upgrading to LM4562HA isn't going to be worth doing imo

I share your opinion on this, but I only tested it in the Caiman prototype layout.

:doh:. I just realized, so did you.

Alright then.

So has anyone been tinkering about with the 7520? Any experimental mods that they want to let us have our hands on?

Plenty of experimental mods, I think its wise to be cautious whats suggested on a public forum though , some idea's could be harder for the causual fiddler to perform on the dac.
I tend to post things I think is easiest for most folks to try

Not sure if the condescending tone is intentional but I'd still like to hear what's brewing in the minds of our top mad DIY scientists.

What condescending tone and which mad scientists :confused:? With that kind of thinkng you aren't going to get any further on AoS. I thought you mentioned you didn't like me the more you knew me. Now you take offense to to straight forward logical advise. Did you land on the wrong forum by mistake?

I'm sure you would, but you think thats a nice way to ask someone to help you?
:)

Guys help out here because they want to, not because they have to.
Its a good bunch on here, but maybe its bad form after only 11 posts to come on here and try to be a cunny funt?
Play nice....
