It's what he does, repeatedly. tweaker has created dozens of threads and they mostly follow the same pattern - ask a (sometimes stupid) question, act like he's clueless, then when people offer their opinions and/or suggestions, he knocks them down one way or another and reveals that he (thinks he) knows the proper answer all along. Once people twig onto this, he starts a new thread. For instance, see the new one about opamps?

Tox, Thanks for the informative reply. Given your electronic engineering background I and maybe we appreciate your detailed info on the RF characteristics of the high grade ceramics vs stacked film, your personal observation of how they sound in comparison to each other, how different brands of stacked film caps sound in comparison to each other and if there may have been any better caps developed for this purpose since the 2004 comments from JR and John Curl. Good, informative and useful reply for me and anyone else that might be interested in this subject matter. The advancement of this hobby is dependent on quality info like you have supplied. Thanks once again. Sincerely, Tweaker
You have quite a bit of info from different people here and what you read, YOU need to do the leg work now. It's your DAC you originally asked about the ceramic caps. So it's up you now to compare for yourself if you really need that info and what brand of stacked caps work best for you, Just like a lot of other have done.
We are here to help you out and if we have a link/s we can supply that but ultimately you have to do the research. Let us know what your results are. Tweak away!
Well Cougar , some B32529 stacked films are on the way. About the dual op amps a OPA2132 is on the way. Suggestions for OPA2604 and OPA2134 are both very good suggestions. These fets are way more musical... than a couple of bi polars I have listened to that people like,IMHO and the OPA2107. It's give and take between the 2134 and 2604. As in everything else opinions vary hugely. If a lot of others have compared different stacked film caps I am not aware of it and no one has responded as such. I'll put these in and hope for an improvement. As to these caps there is no reams of comparisons like in other caps for coupling and crossovers or for that matter any that I could find. Onward and hopefully upward. T
Some will like other types due to more upper end clarity. I like those two I.C's but prefer the OPA2604's. What resistors are you using in the signal path?
In my DIY preamp I used Mills throughout and have been very happy with them. When it was in the prototype faze I swapped out the mills for some Dales metal film. At first they sound better but after 75 hours they were irritating to me for some reason. The cymbals has a abnormal sizzle. I play drums so I know what real cymbal sound and decay are. So I put the Mills back in and everything I liked came back.
Are those stacked film Epcos? I will looking to this soon when I do my Pioneer Elite PD-59 CD player.
Another thing to consider are the Oscon caps for digital circuits. These work well too.
Let us know your results! Hopefully the B32529's are what you were looking for.
The number is an Epcos number . Epcos, TDK and Siemens are all the same it seems. Blue. No idea what crap resistors are in the V-Dac. If and when I get to changing resistors the Takman MF will be my first go to because of the great reviews. In the old days some form of Corning MF sounded better than any other MF we tried at the time. Dale is solid good but not excellent. It's likely that the Z foils are the best. They should be at what they cost. T
