I have received a segment from a copper teflon capacitor courtesy of V-Cap, and I have a foil copper segment from the Psvane. I will e-mail the photo to Grant Fidelity and if needed, mail the foil segments . I can say, the feel of both is not the same. If others want a photo e-mailed let me know or perhaps Grant Fidelity will post the photo...Jallen |
Greetings,
I received the test measurements from my friend and he stated similar findings. The 0.1 600V Psvane caps were measured using method F.T.I.R. Fourier Transformer Infrared Spectroscopy, and the material was determined to be polyester (ethylene terepthalate) and the D.F. test at 1Khz was .005, strongly suggesting mylar inside. When he exposed the material to a soldering iron and heat gun, it melted....doesn't sound like the teflon I know and love.
I will be anxiously awaiting your findings....jallen |
I am afraid some distributors have been deceived about this product, along with consumers. I would like to hear about what Grant Fidelity and Parts Connexion have to say on this matter at this point. Both have great reputations to protect. I wonder if competing entities have evaluated them...Sonicap, V-Cap, Rel, Audience, etc. I would love to hear their comments but understand the reluctance to avoid a net verbal brawl.
Great info. sniper9999, thanks, jallen |
Response to Grant Fidelity,
I will post pics when they arrive in the mail this week. They were not purchased from you, but pc in the last 6 mo. Thanks for your responses, jallen |
On the 1/20/2012 post, the comment from Grant Fidelity stated "I am no plastic expert, but the film does look like teflon". Why not at this time just tell us that the dielectric is BoPet/Polyester Film. It seems that at this time there was some understanding that the Psvane cap had some teflon property to the internal film.... Perhaps the caps are best identified as external copper teflon leads, internal copper polyester film. Consumer awareness in a time when many frauds permeate this industry is paramount to economic recovery in this industry. I appreciate all of your efforts in making the consumers aware of all beneficial information. |
I had hoped to hear from one or more of the other manufacturers as to what adequate product information should be expected. This information, without disclosure of intellectual property, can greatly assist purchasing decisions for consumers. Jallen |
Grant Fidelity, My reference was to the 1/20/2012 post. You clarified this in the 1/31/2012 post. My point was with the 1/20/2012 post, there seemed to be some confusion as the statement was made after cutting a cap open at Grant Fidelity and the appearance was that of "the film does look like teflon to my eyes" and not clarified until your recent post. My point being, there seemed to be some perception even in Canada there was more teflon present than in the leads. Perhaps more than one person there responding to the posts. Again thanks for your efforts, Jallen |
I am surprised to Parts Connexion is on radio silence for this discourse. Are they even aware? There are some good names, hard earned reputations at stake here. |
Have any of you had opportunity to compare the copper or tin caps(v-caps) with others? |
This is a sad day for audio. The quick dollar seems to trump long term market viability. One more reason for the consumer to feel duped and cynical. Kudos to Audiogon for allowing the discourse and exposure. Jallen |
I have heard good things about the REL's, but have read several reviews where the V-Caps were the preferred caps. What was your break-in time for both caps, and what technique did you do to break them if you did. I have used many caps in the past and some do sound much different with 500 hours on them of pink noise, and cycling every 12 hours. Thanks, Jallen |
I have tried the RTX and found them to be a bit compressed sounding, lacking space between instruments. The V-Caps were shrill out of the box, and then went dark at about 200 hours, and at somewhere between 400-500 hours, they became glorious, and all of a sudden everything in the system became suspect. My prior caps were adding a color to the system and removing a layer allowed me to find other weak links. The v-caps allowed the top end to extend like never before....sweet, extended and open. I want to try the CUTF ones, and saw the PSVANE ones, but you can read the story for yourselves. Every circuit may find a different favorite cap, but I believe break in is essential prior to serious evaluation. I have found teflon caps, wires, hookup wire, etc. take a lot of time to break in. I have tried solens and they are OK in a Xover, but not a coupling cap. I use v-Caps, teflon/tin and have trouble finding a description to how they sound. Every recording is so different, their feat is just to get out of the way of the music and let it flow. For a budget cap, I like the Theta polypropylene cap by REL, if you want a decent cap for little money. They are good, but no V-Cap. Arthur Salvatore did an extensive cap eval. and used the REL and V-caps. I have just not found much about the CUTF from V-CAP yet. They may give a mellower sound than the tinfoil ones. Jallen |
I have heard the V-caps in enough circuits and compared with many other caps to feel comfortable stating that they are very neutral, and I hear no edge (with the exception of the first 300 hrs.) And, any " bright sound" has been traced to other parts, tubes, etc. In fact, if they sound harsh, start checking for your weak link, its not the caps. We identified transformers, other caps, interconnects, etc. as adding to the "brightness" of the sound. If you clean the window and don't like the view, don't blame the glass.....jallen |
