Those caps have been brought to my attention, and frankly, after reading the reviews I can't resist the urge to try them. I'm buying a pair today.;)

Wonder if they consider making larger values.
Could use 4 pieces, 33uF of those for a X-CCS-BosoZ:D :D
Steen. |
|
|
| Peter Daniel |
Those 4 pieces would probably cost more than the original Pass preamp ;)
I'm buying only 0.1u values (for high pass amp) as I can't justify 2u cap prices, no matter how good they are. |

Excactly what I mean. Those prices are outragous, to say the least;) 299usd for a 2uF filmcap,
those folks are not ashamed at all:D I sure hope those caps sound good!

| They come with a view that if the caps make bigger difference than power cord and interconnects, thay shouldn't be that much cheaper. In some way they are quite right and we should actually blame cable makers for elevating the prices ;) |

| Bill Fitzpatrick |
| New acronyms like VSQD (Variable Stage Quadrant Dielectric™) are pretty much a dead giveaway that it's just more audiophile thievery. |
|
|

| They should be, by all accounts, great. Still, if possible, i'd rather use a transformer as a coupling device. At these price levels there is a great choice of nice iron. |

Peter, be sure to report back, on your experiences with these caps, when you had a thorough listening session.

As a MSEE I'll summarize this for you: nonsense, this is in the same league as pure silver interlinks with silk dieelectric, 24K golden spikes and audio grade CD-R discs, don't buy into it. There's no substitute for a few smaller polyprop caps in parallel, and certainly not for the frequency range these caps will be used in.
Best regards,

Oh my. I think frequency range has little to do with what these capacitors do better than others.
As a long-time user of teflon capacitors, I can vouch that the V-Caps are excellent capacitors. Their price is quite reasonable considering the considerable cost of teflon. FWIW, V-Caps are cheaper, even, than comparably sized and rated RelCaps, CRC teflon caps, etc. |

| What's so expensive about Teflon? |
|
|
| serengetiplains |
| The manufacture of teflon film in thicknesses required for use in capacitors, and without pinholes, is simply an expensive process, and teflon, of itself, is not a cheap substance. I once ordered a quantity of teflon capacitors from Component Research, a military supplier. The order took 8 months to fill because the company had to reject two batches of teflon film. Winding teflon capacitors is also more labour intensive given that teflon film stretches easily and is so slippery. |
|
|
| SY |
| It's not a cheap material, but there are other polymers that are much worse. For comparison, the last time I priced them, PTFE was about $5-9 per pound ($0.35-0.70 per cubic inch), polypropylene was $0.80 per pound ($0.02 per cubic inch). Polysulfone ran about half of PTFE. PEEK is five times more expensive. |

Come on guys, 299USD for a 2uF cap:) And they even claim it is an introduction offer:bawling: Normal price being 369USD :hot: You could pay the monthly for a car with that:D I for one am not going to invest in those, I would rather have a new complete CD collection then:clown:

| To Peter Daniel : Best cap is no cap - whatabout to make some more sophisticated connection, where caps are not neccessary, than again and again copy LM's datasheet ?:cool: |

I need a cap at the output of my (1543) DAC. I prefer passive I/v over any active stage.
It has nothing to do with copying LM datasheets, but you probably already knew that. |

Like all serious audiophiles, there's nothing more exciting for me then finding a component that dramtically improves the performance of my system. It's that "excitement" and intense pleasure that makes us "audiophiles" in the first place, and is the reason why we are constantly on the look out for something "better", regardless of whether it is new, used, cheap, expensive and difficult to find and set-up. |

If you think that best cap is no cap I can't agree with you more, providing of course you use you 50 cents a piece caps variety.
A good cap in many cases is much better than complicated (and sophistcated) electrical circuit. |

Oh c'mon man, you don't really buy into that do you? Anybody with a highschool education and more than an F on his final physics exam can tell you that this is just another attempt to get some easy cash from the gullible.
Audio is governed by the laws of science, there's no magic involved, hence a magical component that'll dramAtically improve your system's 'audiophile' performance is like believing you can fly if you flap your arms real fast.
A cap is a cap, switching to teflon for the dieelectric will not help in the range where these caps are going to be used. The only way to improve on caps is by taking a few smaller ones in parallel, as I suggested you do with polyprop caps.

You've all heard the expression " A fool and his money are soon parted." ? I think this falls into that category, along with the $500 wooden knob.
There's no way to justify a price of $300 for a small cap like that. |
|
|
| RCBandwidth |
| I would like to see some O-Scope screen captures of your amplifier output with the 300$ capacitors versus a more reasonably priced poly cap.A square wave input to the chip amp with 1khz followed by 10 khz.If you claim to hear these sonic improvements they really should be able to be measured.I doubt that National is using teflon caps when they manufacture the chip,I remain skeptical of your claims. |

Another borg-infested thread.
Peter, the caps require a long so-called break-in time.
By the way, on the subject of good capacitors, I sent a note to Hans of Jensen Capacitors asking if he would wind me some paper-in-oil capacitors using Fluorinert as a dielectric liquid (dielectric constant of 1.7). He responded positively some while back, though I haven't heard from him lately. I'll let you know if anything transpires. |

Next amp I build, I should use stainless steel hookup wire (oxygen free? What's that?) and electrolytic coupling capacitors. Oh, and ceramics. If that doesn't get the audiophools buzzing, I don't know what will.

I'm actually using $2/pc electrolytics for coupling and prefer them over the caps costing 20 times more. |

If you must have PTFE, don't forget that you can get twenty Russian military surplus 0.1µF PTFE caps for the price of only four of these types.

You'll also need a pentode mode push-pull output stage, global negative feedback, class AB operation, no octals, no triodes, SS rectification... ;) |

Peter, I understand your saying. At some point we all end up there. This hobby (obsession:xeye: ) of our's is leading towards things like that. But we still have to consider an investment like that, and value if the outcome is worth the investment;) If some $-heavy guy thinks it is worth it, by all means go ahead. For the rest of us, I don't think so;) Say you need 2 (or 4) of those 2 uF caps, that would be 778$, (or 1556$) Normal pricing! I could find a better place to put that amount of money;)

Having russian military surplus parts in your amp makes it 10 times cooler. :yes:
btw for the people saying teflon is expensive, its nowhere near THAT expensive. They are obviously making a huge profit if they sell any of these caps. |

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
in the event you prefer those you might as well use those
i use caps from tvs lying off the side of the road and surplus
emporiums,prefering oil and paper.
so far $5 is the most i've paid so far
for a single cap (20uf@200v electrocube)
i was in a thrift store,and asked to listen to an "old' and large speaker.
when they played their,check the speakers amp, i could hear the electrolitic
cap grit rather well,indicating that this speaker from the early 50's was
well worth having,whereas their lo-fi recever was less so,to me anyway |

The V-Cap Teflon capacitor was just evaluated in a 21 capacitor "shootout"
by China's largest hi-fi journal, AV Front Line. Chris VenHaus was given permission by the author to

So how do they sound? I thought you were buying a pair a year back? |
|
|
| Peter Daniel |
| Yes, I bought a pair and was using them in my DAC. Recently bought few more, as I'm switching to V-Caps in all my projects now; they are simply the best sounding caps I had so far, very neutral, smooth, transparent with bass that is very well defined. |

My favorite bit from the review:
| quote: | | (M)y heart started racing while writing this section, accompanied by dry mouth, sweaty palms, dilated pupils, and so on... I was literally emotionally choked right after the silver capacitor was installed. |
It's a good thing he didn't try direct coupling or he might still be in Intensive Care.
I liked the bit about the 500 hour break-in time, too. |
