The KillerDAC Audio forum

These are a consideration for output caps for a friends player, I'll head your advise and consider the paper one if it eventuates, the players he has now aren't really worth modding so he's on the eye out for something better.

Thanks, Steve.

Info from a seller of these caps .

But I have felt the tone of metalized polypropylene capacitors don’t have the natural warmth of human touch, and lacks the true naturalness of the hermetic seal oil-filled capacitor that is made of mainly Kraft paper as the dielectric. I suppose it might come from the fact that the frequency also has a level of characteristic vibration, and with polypropylene it would be higher because of the high Young’s modulus (hardness) and the small value of internal loss. I think the metalized electrode might emphasize the tendency.

As the title asks

Read a little about them on the net, and am curious if anyone has tried them here? 

They describe the sound of these caps with one word 'Real' apparently.

I would not go for the Mylar dielectric. In the past i have had ordinary results with that material. The Kraft paper dielectric model looks more interesting to me, paper is usually more natural sounding .

I have never heard of them, but i will read about them right now, always interested in a new capacitor

Yes sorry, forgot to mention the First Ultimates in the heading.

Weak bass  ..................hmmmmm, not so sure I agree with that Stevo, I have heard them with the Wilson Grand Slams and there certainly was no lack of either deep bass or bass slam.  I find that in the right system they do not lack dynamics at all but they are free from the usual 'glare' and false emphasis on leading edge notes that some lesser cables produce.  I take it you listened to them for more than a week to arrive at this conclusion?  I am guessing that a system rebalance was not looked at to accomodate them in such a highly tuned system.  OB bass is never going to dig too deep without huge eq and power.

I agree with the organic almost polite presentation but by not emphasisng any particualr octave pays off trumps in many systems.  I have the screened and unscreened versions and they reside in my top ten interconnects for a reasonable price category.  Pure silver cables I have a couple of different versions of and agree that detail is more obvious with this material but they lack the naturalness of the VDH Ultimates.  As usual it comes down to tuning your system around the final balance requied but worth a try for those with overly bright and agressive sounds, they demuddle with ease and allow more insight much like a good valve pre or KD output stage.

A very good summary. I find that they do vocals particularly well, giving them warmth and naturalness though some recordings are so bad they cant help those. Yes they can help make a system that is a a bit bright and edgy more livable as well. The Van den hul golds are very a good as well.

I have some tasty 6J5s here rare brown base. Half of a 6SN7. I find with most tubes there is no real set parameter, usually is just trial and error, and you are right there is a sweet spot. That is why a variable resistor is handy.

Yes thats what Paul Baker and I have found, its trial and error. Getting the sweet spot can make quite a difference with some valves.
