V-Cap Odam or Miflix output caps In preamp

I understand this is an older thread but I wanted to provide some insight (as I know many folk find these threads via a Google search). I would have to honestly say that in my experience in dozens of amplifiers and preamps that I've tried them in, the Miflex beats the Odam in every category that is important to me- more organic tone, more transparency and a more natural midrange. I think the Odam lack good lower midrange/upper bass delineation and I simply cannot enjoy them over time- far beyond 300-500 hours, so burn in is not a concern. The Odams do seem more extended in the highs and deeper in the bass, but I have to try to convince myself that this is better. With the Miflex (once adequately burned in) everything simply sounds more right/real/correct to me. Of course, YMMV but I do not care for the Odams.

Hi all, Just to add some more "spice" to the conversation I wanted to add some additional impressions. I've found a variable which may be useful regarding these caps. 

In lower voltage first stage of a few amplifiers I've tried the Odams in, I found them rather extended on both extremes, but somewhat dark in the midband compared to many other caps I've tried. In this scenario the Miflex did the trick and we're very detailed and engaging without any perceived forwardness. 

However in a higher voltage stage where the B+ was closer to 400 volts, the Odams really shined! I found them to be more transparent and neutral here without any of the slight thickness or darkness down below. In this case, the Miflex sounded a tad unrefined in the upper midrange and lower treble. I've concluded that the type of circuit and working voltage make a profound difference over what sounds "best". 

My thoughts are that, since capacitors have two functions (to block DC and pass AC music signals), these may not be mutually exclusive functions and rather somewhat tied into what we hear. 

I've also found this to be true with the Audyn True Copper caps, and I love each of the three, albeit in different situations. 

 

All the best, Aric

@linnlp12  Could you please reference the article that you're referring to? The only one I could find was where Troels Gravesen upgraded an EAR 861 with the Miflex "KFPM" (not the oil-filled KPCU) and he makes no note of how the capacitors sound, just that a faulty tube caused some noises in the amp and he replaced the tubes. He states his friend could not tell whether it was the caps or the new tubes which made the amp sound better.

@sns I wasn't saying either about the True Coppers as I find them equally enjoyable in higher or lower voltage circuits. I'm mainly saying that each can have a different situation where I find them to sound best. I hope this helps, Aric
