Yes, Carlos. I know that too much filtering is a bad thing.
The AKM dac has switched capacitors filter inside, some 6dB/oct filtering. So your advice is good.
I think that IÂ´ll do some experiments with opa602 and some minimal filtering.
Is a nice opamp that opa602; I reccomend it very much: not so overwhelming on paper, but when you note that all the specs are measured with 500pF and 1k at the output, the device makes more sense.
Well suited to drive capacitive cables, low impedances, etc.
Is very good on vocals, with a smooth quality difficult to describe.
I prefer it to opa627 -even with heavy decoupling, etc-
I know that this is a entirelly subjective appreciation, but the difference is very noticeable. Maybe IÂ´m pursuing this kind of sound...
How many times did I come back to my bench, because what I thought was "technically" a better solution didn't sound good?
Yes, is common...
IÂ´m thinking seriously in obtain some oscilloscope to do more measurements, and to avoid Â¨tocar de ouvidoÂ¨ (playing by ear, an expression to signify Â¨improvisationÂ¨).
You make me laugh a lot with that Â¨Thick as a BrickÂ¨ joke...
ItÂ´s difficult to express some very technical things in a forum, more so for the amateur. And I`m new here, so I donÂ´t know whether express myself in some decontractÃ¨ way -you know, telling jokes and so-, or in a more solemn manner
. For what I have seen, the tone of the postings here is not very stiff; more the other way around: funny.
Alas, sorry for my rawness.
Obrigado, and cheers.
